				Safety Rules   
					& Information   
					Read these safety rules and follow them closely. Failure to obey these rules could result in loss of con-   
					trol of unit, severe personal injury or death to you, or bystanders, or damage to property or equipment.   
					This mowing deck is capable of amputating hands and feet and throwing objects. The triangle in   
					text signifies important cautions or warnings which must be followed.   
					TRAINING   
					• Read, understand, and follow all instructions in the   
					manual and on the unit before starting. If the opera-   
					tor(s) or mechanic(s) can not read English it is the   
					owner’s responsibility to explain this material to them.   
					• The owner/user can prevent and is responsible for   
					accidents or injuries occurring to themselves, other   
					people or property.   
					• Data indicates that operators, age 60 years and   
					above, are involved in a large percentage of riding   
					mower-related injuries. These operators should eval-   
					uate their ability to operate the riding mower safely   
					enough to protect themselves and others from seri-   
					ous injury.   
					• Become familiar with the safe operation of the equip-   
					ment, operator controls, and safety signs.   
					• All operators and mechanics should be trained. The   
					owner is responsible for training the users.   
					• Only allow responsible adults, who are familiar with   
					the instructions, to operate the unit.   
					• Never let children or untrained people operate or   
					service the equipment. Local regulations may   
					restrict the age of the operator.   
					PREPARATION   
					• Evaluate the terrain to determine what accessories   
					and attachments are needed to properly and safely   
					perform the job. Use only accessories and attach-   
					ments approved by the manufacturer.   
					• Wear appropriate clothing including safety shoes,   
					safety glasses and ear protection. Long hair, loose   
					clothing or jewelry may get tangled in moving parts.   
					• Inspect the area where the equipment is to be used   
					and remove all objects such as rocks, toys and wire,   
					which can be thrown by the machine.   
					• Use extra care when handling gasoline and other   
					fuels. They are flammable and vapors are explosive.   
					a) Use only an approved container.   
					b) Never remove fuel cap or add fuel with the engine   
					running. Allow engine to cool before refueling. Do   
					not smoke.   
					c) Never refuel or drain the machine indoors.   
					• Check that operator’s presence controls, safety   
					switches and shields are attached and functioning   
					properly. Do not operate unless they are functioning   
					properly.

				Safety Rules & Information   
					OPERATION   
					• Never run an engine in an enclosed area.   
					• Mow only in the daylight or with good artificial light,   
					keeping away from holes and hidden hazards.   
					• Never operate with guards not securely in place. Be   
					sure all interlocks are attached, adjusted properly   
					and functioning properly.   
					• Be sure all drives are in neutral and parking brake is   
					engaged before starting engine. Only start engine   
					from the operator’s position. Use seat belts if provid-   
					ed.   
					• Be sure of your footing while using pedestrian con-   
					trolled equipment, especially when backing up. Walk,   
					don't run.   
					• Do not mow in reverse unless absolutely necessary.   
					Always look down and behind before and while trav-   
					eling in reverse.   
					• Be aware of the mower discharge direction and do   
					not point it at anyone. Do not operate the mower   
					without either the entire grass catcher or the deflec-   
					tor in place.   
					• Never operate with the discharge deflector raised,   
					removed or altered, unless using a grass catcher.   
					• Do not change the engine governor setting or over-   
					speed the engine.   
					• Stop on level ground, lower implements, disengage   
					drives, engage parking brake, shut off engine before   
					leaving the operator’s position for any reason includ-   
					ing emptying the grass catchers or unclogging the   
					chute.   
					• Stop equipment and inspect blades after striking   
					objects or abnormal vibration occurs. Make neces-   
					sary repairs before resuming operations.   
					• Keep hands and feet away from the cutting units.   
					• Never carry passengers and keep pets and   
					bystanders away.   
					• Do not operate the unit while under the influence of   
					alcohol or drugs.   
					• Slow down and use caution when making turns and   
					when changing directions on slopes.   
					• Never raise deck with the blades running.   
					• Never leave a running unit unattended. Always disen-   
					gage the PTO, set parking brake, stop engine, and   
					remove keys before dismounting. Keep hands and   
					feet away from the cutting units.   
					• Turn off the PTO switch to disengage the blades   
					when not mowing.   
					• Slow down and use caution when making turns and   
					crossing roads and sidewalks. Stop blades if not   
					mowing.   
					• Use care when loading or unloading the machine   
					into a trailer or truck.   
					• Use care when approaching blind corners, shrubs,   
					trees or other objects that may obscure vision.   
					SLOPE OPERATION   
					WARNING   
					Slopes are a major factor related to loss-of-control and tip-   
					over accidents, which can result in severe injury or death.   
					All slopes require extra caution. If you cannot back up the   
					slope or if you feel uneasy on it, do not drive on it.   
					Never operate on slopes greater than 20°   
					(36.4 percent) which is a rise of 7-1/4 feet (220 cm)   
					vertically in 20 feet (607 cm) horizontally.   
					Select slow ground speed before driving onto slope.   
					In addition to front and rear weights, use extra caution   
					when operating on slopes with rear-mounted grass   
					catcher.   
					Mow ACROSS the slope, never up and down the   
					face, use caution when changing directions and DO   
					NOT START OR STOP ON SLOPE.   
					Do   
					Do Not   
					• Mow across the face of slopes; never up and down.   
					• Remove obstacles such as rocks, tree limbs, etc.   
					• Watch for holes, ruts, or bumps. Uneven terrain   
					could overturn the unit. Tall grass can hide obsta-   
					cles.   
					• Do not start or stop on a slope. If tires lose traction,   
					disengage the blade(s) and proceed slowly straight   
					down the slope.   
					• Do not turn on slopes unless necessary, and then,   
					turn slowly and gradually downhill, if possible.   
					• Do not mow near drop-offs, ditches, or embank-   
					ments. The operator could lose footing or balance or   
					mower could suddenly turn over if a wheel is over   
					the edge of a cliff or ditch, or if an edge caves in.   
					• Do not mow on wet grass. Reduced footing or trac-   
					tion could cause sliding.   
					• Do not try to stabilize the unit by putting your foot on   
					the ground.   
					• Do not mow excessively steep slopes.   
					• Use slow speed. Choose a slow speed so that you   
					will not have to stop or change speed while on the   
					slope.   
					• Use extra care with grass catchers or other attach-   
					ments. These can change the stability of the unit.   
					• Keep all movement on the slopes slow and gradual.   
					Do not make sudden changes in speed or direction.   
					• See your authorized dealer for recommendations of   
					available weights to improve stability.   
					• Do not use grass catcher on steep slopes.

				Features & Controls   
					D. Parking Brake Handle   
					SAFETY INTERLOCK   
					SYSTEM   
					The parking brake is applied by pushing DOWN on the   
					parking brake handle until it stops. To release the park-   
					ing brake, pull UP on the handle until it locks over cen-   
					ter.   
					This unit is equipped with safety interlock switches.   
					These safety systems are present for your safety, do not   
					attempt to bypass safety switches, and never tamper   
					with safety devices. Check their operation regularly.   
					E. PTO (Power Take Off) Switch   
					The PTO switch engages and disengages the mower.   
					Pull UP on the switch to engage, and push DOWN to   
					disengage.   
					Operational SAFETY Checks   
					Test 1 — Engine should NOT crank if:   
					F. Operator Presence Handles   
					• PTO switch is engaged, OR   
					These handles are a major factor in the safety interlock   
					system of the mower. Both handles are tied together so   
					depressing one handle depresses both. The operator   
					must depress the handles in order to disengage the   
					parking brake and engage the PTO switch.   
					• Parking brake is not engaged, OR   
					• Motion control handle is not in the NEUTRAL posi-   
					tion   
					Test 2 — Engine SHOULD crank if:   
					G & H. Throttle / Choke Control   
					• PTO switch is NOT engaged, AND   
					• Parking brake is engaged, AND   
					Pulling the round choke control knob (H) out fully chokes   
					the engine for cold starts. (A warm engine may not   
					require choking.) Moving the throttle control (G) fully   
					towards the right is FULL throttle position. Always oper-   
					ate the unit at FULL throttle when mowing.   
					• Motion control handle is in the NEUTRAL position   
					Test 3 — Engine should SHUT OFF if:   
					• Operator releases the operator presence handles   
					with PTO engaged, OR   
					I. Neutral Return Pedal   
					• Operator releases the operator presence handles   
					with parking brake disengaged.   
					The neutral return pedal provides a hands-free return to   
					neutral. This is used in conjunction with the Reverse   
					Speed Control Levers (B) to properly stop the machine.   
					Test 4 — Blade Brake Check   
					Mower blades and mower drive belt should come to a   
					complete stop within seven seconds after electric PTO   
					switch is turned off (or operator releases the operator   
					presence handles). If mower drive belt does not stop   
					within seven seconds, see your dealer.   
					See the Operating the Dual Drive Walk-Behind Mower   
					section for steering instructions.   
					J. Fuel Shut Off Valve (not shown)   
					The fuel shut off valve is located under the fuel tank.   
					Turning the handle until it is VERTICAL will allow fuel to   
					be supplied to the engine. Turning the handle until it is   
					HORIZONTAL shuts off the fuel supply to the engine.   
					NOTE: Once the engine has stopped, PTO switch must   
					be turned off, parking brake must be engaged, and the   
					motion control handle must be returned to the NEU-   
					TRAL position in order to start the engine.   
					WARNING   
					If the unit does not pass a safety test, do not   
					operate it. See your authorized dealer. Under no   
					circumstance should you attempt to defeat the

					DRIVING THE MOWER   
					WARNING   
					The hydrostatic transmission has an infinite number of   
					speeds between full speed forward and reverse, with the   
					faster speeds being achieved by moving the speed con-   
					trol lever and steering control levers farthest in the direc-   
					tion of travel.   
					If you do not understand how a specific control   
					functions, or have not yet thoroughly read the   
					FEATURES & CONTROLS section, do so now.   
					Do NOT attempt to operate the tractor without   
					first becoming familiar with the location and   
					function of ALL controls.   
					TO MOVE FORWARD   
					1. Disengage the parking brake.   
					2. Gently move the speed control lever forward until   
					desired speed is achieved.   
					STARTING THE ENGINE

					STORAGE   
					WARNING   
					Never store the unit, with gasoline in engine or   
					fuel tank, in a heated shelter or in enclosed,   
					poorly ventilated enclosures. Gasoline fumes may   
					reach an open flame, spark or pilot light (such as   
					a furnace, water heater, clothes dryer, etc.) and   
					cause an explosion.   
					Temporary Storage (30 Days Or Less)   
					Remember, the fuel tank will still contain some gasoline,   
					so never store the unit indoors or in any other area   
					where fuel vapor could travel to any ignition source. Fuel   
					vapor is also toxic if inhaled, so never store the unit in   
					any structure used for human or animal habitation.   
					Handle gasoline carefully. It is highly flammable   
					and careless use could result in serious fire   
					damage to your person or property.   
					Here is a checklist of things to do when storing your unit   
					temporarily or in between uses:   
					• Keep the unit in an area away from where children   
					may come into contact with it. If there’s any chance   
					of unauthorized use, remove the spark plug (s) and   
					put in a safe place. Be sure the spark plug opening is   
					protected from foreign objects with a suitable cover.   
					Drain fuel into an approved container outdoors   
					away from open flame or sparks.   
					10. Drain fuel system completely or add a gasoline stabi-   
					lizer to the fuel system. If you have chosen to use a   
					fuel stabilizer and have not drained the fuel system,   
					follow all safety instructions and storage precautions   
					in this manual to prevent the possibility of fire from   
					the ignition of gasoline fumes. Remember, gasoline   
					fumes can travel to distant sources of ignition and   
					ignite, causing risk of explosion and fire.   
					• If the unit can’t be stored on a reasonable level sur-   
					face, chock the wheels.   
					• Clean all grass and dirt from the mower.   
					Long Term Storage (Longer Than 30 Days)   
					Before you store your unit for the off-season, read the   
					Maintenance and Storage instructions in the Safety   
					Rules section, then perform the following steps:   
					NOTE: Gasoline, if permitted to stand unused for   
					extended periods (30 days or more), may develop   
					gummy deposits which can adversely affect the engine   
					carburetor and cause engine malfunction. To avoid this   
					condition, add a gasoline stabilizer to the fuel tank and   
					run the engine a few minutes, or drain all fuel from the   
					unit before placing it in storage.   
					1. Drain crankcase oil while engine is hot and refill with   
					a grade of oil that will be required when unit is used   
					again.   
					2. Prepare the mower deck for storage as follows:   
					a. Remove mower deck from the unit.   
					b. Clean underside of mower deck.   
					STARTING AFTER LONG TERM   
					STORAGE   
					Before starting the unit after it has been stored for a long   
					period of time, perform the following steps.   
					c. Coat all bare metal surfaces with paint or light coat   
					of oil to prevent rusting.

					DECK LEVELING ADJUSTMENT   
					(DDSH Models only)   
					1. Make sure there is one spacer above and below the   
					frame on the front caster shafts and place hairpin   
					clips in the 2” cutting height position (see Figure 17).   
					B 
					2. Rotate the blade on the RIGHT-HAND side (dis-   
					charge side) until the tip faces the front of the   
					machine.

					3. Loosen the jam nuts (A, Figure 18) located on the   
					front deck hanger shafts (B, Figure 18). Turn the   
					right side shaft until a cutting height of 2” is obtained   
					at the very tip of the blade towards the front of the   
					machine.   
					B 
					A 
					Figure 18. Front Hanger Shaft Adjustment

					B. Front Hanger Shaft   
					4. Now place a straight edge on top of the cutter deck   
					approximately 1” to the outside of the front deck   
					mount on the right side and measure to the floor   
					(see Figure 19). Record your measurement.   
					5. Repeat the measuring procedure listed in Step 4 for   
					the left-hand side of the mower deck.   
					Straight Edge   
					Measure Here   
					6. Compare the measurements taken in Step 4 & 5. If   
					they differ by more than 1/16”, the front deck hanger   
					shaft on the LEFT side (non-discharge side) must be   
					adjusted.   
					7. Adjust the two front hanger shafts as needed until   
					the tip of the blade is 2” from the floor and the meas-   
					urements taken from the top of the deck to the floor   
					are within 1/16" of each other.   
					Figure 19. Mowing Height Measurement   
					8. Once the level of the deck has been adjusted, there   
					should be no slack in the front hanger shafts. If one   
					shaft moves, a shim (P/N 20928) is required.

				Troubleshooting, Adjustment & Service   
					Shimming the Hanger Shafts   
					B 
					Once it has been determined that a shim (P/N 20928) is   
					required, you first must determine which rear hanger   
					shaft requires the shim.   
					A 
					The shim (A, Figure 20) must be placed in between the   
					spacer (B, Figure 20) and the retaining collar (C, Figure   
					20) on the OPPOSITE side from which the front shaft   
					has movement or slack (see Figure 21).   
					C 
					Once the shim has been assembled in the proper loca-   
					tion, repeat Step 2 - 8 in the DECK LEVELING   
					ADJUSTMENT section. This adjustment may need to   
					be repeated more than once until the proper number of   
					shims has been installed to obtain the proper cutting   
					height, equal measurements from side to side and no   
					movement of the front hanger shafts.

				Troubleshooting, Adjustment & Service   
					TRANSMISSION MAINTENANCE   
					AND SERVICE   
					B 
					The hydrostatic transmissions are sealed units that   
					require no maintenance other than the following.   
					• Keep the grass screen and transmission cooling fins   
					clear or grass, leaves and debris.   
					• Keep oil level in the reservoirs (A, Figure 30) at the   
					“FULL” line (B, Figure 30). Extra oil in the reservoir   
					will not benefit the machine.   
					C 
					• If it is necessary to add oil to the reservoirs, use SAE   
					straight 20 or 30 weight motor oil. DO NOT use a   
					multi-grade oils. Make sure the area around the oil   
					reservoirs is free from dust, dirt and debris before   
					opening the reservoirs.   
					Figure 30. Oil Reservoirs   
					A. Oil Reservoirs   
					B. “FULL” Line   
					• Make sure the oil reservoirs caps are tight.   
					• Keep water, dirt and debris from entering the oil   
					reservoirs. A small amount of a contaminant could   
					damage the transmissions.   
					Changing Oil & Filters   
					Make sure transmissions and imme-   
					diate surrounding areas are free from   
					dirt and debris before changing the   
					oil and filters. Cleanliness while per-   
					forming this operation is extremely   
					important.   
					1. Park the machine on a smooth, level surface such as   
					a concrete floor. Disengage the PTO, engage the   
					parking brake, turn off the engine, and remove the   
					ignition key.   
					Figure 31. Transmission Oil Filter Location   
					(left-hand side shown)   
					2. Place a drain pan under each transmission and   
					remove the filters to drain the oil. See Figure 31.   
					3. Once oil has drained from transmissions, replace   
					with new filters (P/N 21068-1), placing a light film on   
					the seal of the filter before installing. Hand-tighten   
					filter only.   
					4. Fill oil reservoirs 3/4 full with SAE straight 20 or 30   
					weight motor oil.   
					To Bleed Air From Transmissions   
					3. Run engine for 15 minutes. Watch the oil level in the   
					reservoirs. Add oil to the “FULL” line (B, Figure 30)   
					as necessary.   
					1. Locate the machine in a secure area, away from   
					bystanders and preferably facing a wall. Raise the   
					drive tires off the ground and secure with jackstands.   
					4. Watch oil levels for the next few days and add oil to   
					the reservoirs as necessary.   
					2. Start the engine and adjust throttle control to FULL   
					(highest setting). See the STARTING THE ENGINE   
					section for proper starting instructions.

					WARNING   
					Check the PTO clutch adjustment after the initial 50 hour   
					break-in period and then after every 250 hours of opera-   
					tion. Also perform the following procedure if the clutch is   
					slipping or will not engage, or if a new clutch has been   
					installed.   
					To avoid serious injury, perform adjustments only   
					with engine stopped, key removed and machine   
					on level ground.   
					Blade Brake Check   
					1. Remove key from ignition switch and disconnect   
					spark plug wires to prevent the possibility of acciden-   
					tal starting while the PTO is being adjusted.   
					Mower blades and mower drive belts should come to a   
					complete stop within seven seconds after electric PTO   
					switch is turned off.   
					2. See Figure 32. Note the position of the 3 adjustment   
					windows (A) in the side of the brake plate and the   
					nylock adjustment nuts (B).   
					1. Remove deck guard(s) for checking blade brake stop   
					time ONLY. NEVER OPERATE the machine without   
					guard(s) in place.   
					3. Insert a .012”-.018” (0,30-0,45mm) feeler gauge (C)   
					through each window, positioning the gauge between   
					the rotor face and the armature face as shown in   
					Figure 33.   
					1. With parking brake engaged and PTO disengage,   
					start the engine engine.   
					2. Observe the mower drive belt. Engage the PTO and   
					wait several seconds. Disengage the PTO and check   
					the amount of time it takes for the mower drive belt   
					to stop.   
					4. Alternately tighten the adjustment nuts (B, Figure 32)   
					until the rotor face and armature face just contacts   
					the gauge.   
					3. If the mower drive belt does not stop within seven   
					seconds, perform the PTO Clutch Adjustment. If the   
					belt still does not stop within seven seconds, see

					5. Check the windows for an equal amount of tension   
					when the gauge is inserted and removed, and make   
					any necessary adjustments by tightening or loosen-   
					ing the adjustment nuts.   
					NOTE: The actual air gap between the rotor and arma-   
					ture may vary even after performing the adjustment pro-   
					cedure. This is due to dimensional variations on compo-   
					nent parts, and is an acceptable condition.   
					6. Check the mower blade stopping time. The mower   
					blades and mower drive belt should come to a com-   
					plete stop within seven seconds after the electric   
					PTO switch is turned off.

					Jump Starting With Auxiliary (Booster)   
					Battery   
					BATTERY SERVICE   
					WARNING   
					Keep open flames and sparks away from the   
					battery; the gasses coming from it are highly   
					explosive. Ventilate the battery well during   
					charging.   
					Jump starting is not recommended. However, if it must   
					be done, follow these directions. Both booster and dis-   
					charged batteries should be treated carefully when using   
					jumper cables. Follow the steps below EXACTLY, being   
					careful not to cause sparks. Refer to Figure 34.   
					1. Both batteries must be of the same voltage.   
					2. Position the vehicle with the booster battery adjacent   
					to the vehicle with the discharged battery so that   
					booster cables can be connected easily to the batter-   
					ies in both vehicles. Make certain vehicles do not   
					touch each other.   
					Checking Battery Voltage   
					A voltmeter can be used to determine condition of bat-   
					tery. When engine is off, the voltmeter shows battery   
					voltage, which should be 12 volts. When engine is run-   
					ning, the voltmeter shows voltage of charging circuit   
					which normally is 13 to 14 volts.   
					3. Wear safety glasses and shield eyes and face from   
					batteries at all times. Be sure vent caps are tight.   
					Place damp cloth over vent caps on both batteries.   
					A dead battery or one too weak to start the engine may   
					not mean the battery needs to be replaced. For exam-   
					ple, it may mean that the alternator is not charging the   
					battery properly. If there is any doubt about the cause of   
					the problem, see your dealer. If you need to replace the   
					battery, follow the steps under Cleaning the Battery &   
					Cables in the Regular Maintenance Section.   
					4. Connect positive (+) cable to positive post of dis-   
					charged battery (wired to starter or solenoid).   
					5. Connect the other end of same cable to same post   
					marked positive (+) on booster battery.   
					6. Connect the second cable negative (-) to other post   
					of booster battery.   
					7. Make final connection on engine block of stalled   
					vehicle away from battery. Do not lean over batter-   
					ies.   
					Charging a Completely Discharged Battery   
					1. Be aware of all the safety precautions you should   
					observe during the charging operation. If you are   
					unfamiliar with the use of a battery charger and   
					hydrometer, have the battery serviced by your dealer.   
					8. Start the engine of the vehicle with the booster bat-   
					tery. Wait a few minutes, then attempt to start the   
					engine of the vehicle with the discharged battery.   
					2. Add distilled water sufficient to cover the plate (fill to   
					the proper level near the end of the charge). If the   
					battery is extremely cold, allow it to warm before   
					adding water because the water level will rise as it   
					warms. Also, an extremely cold battery will not   
					accept a normal charge until it becomes warm.   
					9. If the vehicle does not start after cranking for thirty   
					seconds, STOP PROCEDURE. More than thirty sec-   
					onds seldom starts the engine unless some mechan-   
					ical adjustment is made.   
					10. After starting, allow the engine to return to idle   
					speed. Remove the cable connection at the engine   
					or frame. Then remove the other end of the same   
					cable from the booster battery.   
					3. Always unplug or turn the charger off before attach-   
					ing or removing the clamp connections.   
					4. Carefully attach the clamps to the battery in proper   
					polarity (usually red to [+] positive and black to [-]   
					negative).   
					11. Remove the other cable by disconnecting at the dis-   
					charged battery first and then disconnect the oppo-   
					site end from the booster battery.   
					5. While charging, periodically measure the tempera-   
					ture of the electrolyte. If the temperature exceeds   
					125° F (51.6° C), or if violent gassing or spewing of   
					electrolyte occurs, the charging rate must be reduced   
					or temporarily halted to prevent battery damage.   
					12. Discard the damp cloths that were placed over the   
					battery vent caps.   
					6. Charge the battery until fully charged (until the spe-   
					cific gravity of the electrolyte is 1.250 or higher and   
					the electrolyte temperature is at least 60° F). The   
					best method of making certain a battery is fully   
					charged, but not over charged, is to measure the   
					specific gravity of a cell once per hour. The battery   
					is fully charged when the cells are gassing freely at   
					low charging rate and less than 0.003 change in spe-   
					cific gravity occurs over a three hour period.

					WARNING   
					Any procedure other than the preceding could   
					result in:   
					For your personal safety, use extreme care when   
					jump starting. Never expose battery to open flame   
					or electric spark – battery action generates   
					hydrogen gas which is flammable and explosive.   
					Do not allow battery acid to contact skin, eyes,   
					fabrics, or painted surfaces. Batteries contain a   
					sulfuric acid solution which can cause serious   
					personal injury or property damage.   
					(1) personal injury caused by electrolyte   
					squirting out the battery vents,   
					(2) personal injury or property damage due to   
					battery explosion,   
					(3) damage to the charging system of the   
					booster vehicle or of the immobilized   
					vehicle.   
					When removing or installing battery cables,   
					disconnect the negative cable FIRST and   
					reconnect it LAST. If not done in this order, the   
					positive terminal can be shorted to the frame by a   
					tool.   
					Do not attempt to jump start a vehicle having a   
					frozen battery because the battery may rupture or   
					explode. If a frozen battery is suspected, examine   
					all fill vents on the battery. If ice can be seen or if   
					the electrolyte fluid cannot be seen, do not   
					attempt to start with jumper cables as long as the   
					battery remains frozen.   
					To avoid engine damage, do not disconnect   
					battery while engine is running. Be sure terminal   
					connections are tight before starting.

					• How and When to Water, Fertilize & Aerate   
					• How High to Mow the Grass   
					• When and How Often to Mow   
					• What Mowing Patterns to Use   
					GENERAL INFORMATION   
					Proper mowing is an important part of maintaining your   
					lawn in the best possible condition. A healthy and well   
					maintained lawn is better able to resist drought, weeds,   
					and other stresses. But too much maintenance is as   
					detrimental to your lawn as neglect. Proper care for your   
					lawn involves more than just “cutting the grass.” To have   
					a healthy lawn, you need to know:   
					• Proper Mowing Methods   
					• How to Solve Common Mowing Problems   
					TYPES OF GRASS, CLIMATE AND   
					CONDITIONS   
					A variety of grasses are commonly grown in household   
					lawns, but two main groups known as cool-season   
					grasses (varieties of bluegrass, ryegrass, and fescue),   
					and warm-season grasses (typically bermuda, buffalo   
					grass, and zoysia varieties) are the most common.   
					The cool-season grasses are better suited to cooler cli-   
					mates, and do not endure hot and dry weather as well as   
					warm-season grasses, but conversely, the warm-season   
					grasses do not grow as well in cooler climates. Most resi-   
					dential lawns are typically seeded with a mixture of these   
					grasses. (A local nursery or lawn center may help you to   
					identify what kind of grass your lawn contains from a   
					sample.)   
					HOW TO WATER YOUR LAWN   
					Knowing your climate and conditions is also important to   
					proper lawn care. Drier climates or conditions will require   
					additional watering, while wetter climates may require   
					more frequent mowing.   
					The best method of watering a lawn is to imitate a slow,   
					soaking rain, applying about 1 inch of water. A method   
					of verifying the amount that you have watered, is to place   
					several empty tin cans (low shallow cans work best) in   
					various spots around the lawn, and check the depth of   
					water in the can during the watering process.   
					HOW AND WHEN TO WATER,   
					FERTILIZE & AERATE   
					HOW TO FERTILIZE YOUR LAWN   
					Fertilizing with a slow-release fertilizer provides missing   
					nutrients which help create slow, even growth. While   
					opinions vary on the need for fertilizing, when and how   
					much to fertilize will be more a factor of the condition of   
					the lawn and soil than any routine. Remember that over-   
					fertilizing can cause harm, and that most fertilizing   
					should be applied in the spring so that it will release into   
					the lawn through the summer. For more information,   
					check with a local nursery or lawn care specialist, and   
					read and follow the fertilizer manufacturer’s instructions.   
					Every lawn’s watering needs are unique and are depen-   
					dent upon the type of grass and soil, the amount of local   
					rainfall, and other conditions. Most lawns are watered   
					too often, but with too little water. However too much   
					water can allow development of diseases with your lawn.   
					It is best to water the lawn only when necessary, and   
					then to water it slowly, evenly, and deeply—imitating   
					a slow, soaking rain.   
					WHEN TO WATER YOUR LAWN   
					AERATING YOUR LAWN   
					When the lawn begins to wilt, the grass’s color dulls, or   
					footprints stay compressed for more than a few seconds,   
					the lawn is beginning to dry out, and needs additional   
					moisture. The best time to water is early morning to allow   
					the water to soak deeply into the lawn and reduce the   
					amount that evaporates in the hot afternoon sun.   
					Consider aerating your lawn in spring. Using an aerator   
					to remove cores of soil from the lawn increases the   
					speed of clipping decomposition and encourages deeper   
					root growth by opening up the soil and permitting greater   
					movement of water, fertilizer and air.

					HOW HIGH TO   
					Cut less than   
					MOW THE GRASS   
					1/3   
					Often cutting height is a   
					matter of personal prefer-   
					ence. Typically, you should   
					mow the grass when it is is   
					between three and five   
					Optimal   
					cutting point   
					at less than   
					1/3 from top   
					of grass blade   
					inches high. The proper   
					cutting height range for a   
					specific lawn will depend   
					upon several factors,   
					including the type of grass,   
					the amount of rainfall, the   
					prevailing temperature, and   
					the lawn’s overall condition.   
					Cutting down to this   
					area contributes to   
					thatch problems   
					Cutting the grass too short   
					causes weak, thin grass   
					plants, which are easily   
					damaged by dry periods   
					and pests. Cutting too short   
					is often more damaging   
					than allowing the grass to be slightly higher.   
					Letting grass grow a bit longer—especially when it is hot and   
					dry—reduces heat build-up, preserves needed moisture and   
					protects the grass from heat damage and other problems.   
					However, allowing grass to grow too high can cause thin turf   
					and additional problems.   
					1/3   
					Cutting off too much at one time shocks the plant’s growth   
					system and weakens the grass plants. A good rule of   
					thumb is the 1/3 rule: to cut no more than one third of   
					the grass height, and never more than 1 inch at a time.   
					The amount of grass you are able to cut in one pass is also   
					effected by the type of mowing system you are using (for   
					example, broadcasting with side discharge decks can   
					process a much larger volume of grass than mulching does).   
					1 inch   
					NOTE: We cover some specific mowing instructions for   
					mulching and broadcasting later in this Lawn Care section.   
					Proper Cutting Height

					First Pass   
					Cut   
					Tall Grass Requires Incremental Cutting   
					Here On   
					Second   
					Pass   
					For extremely tall grass, set the cutting height at maxi-   
					mum for the first pass, and then reset it to the desired   
					height and mow a second or third time.   
					Don’t cover the grass surface with a heavy layer of   
					clippings. Consider using a grass collection system   
					and starting a compost pile.

				Lawn Care & Mowing Information   
					WHEN AND HOW OFTEN TO MOW   
					The time of day and condition of the grass greatly affect   
					the results you’ll get when mowing. For the best results,   
					follow these guidelines:   
					l Mow when the grass is between three and five inches   
					high.   
					l Mow with sharp blades. Short clippings of grass one   
					inch or shorter decompose more quickly than longer   
					blades. Sharp mower blades cut grass cleanly and   
					efficiently, preventing frayed edges which harm the   
					grass.   
					l Mow at time of day when the grass is cool and dry.   
					Late afternoon or early evening often provide these   
					ideal mowing conditions.   
					l Avoid mowing after rain or even heavy dew, and   
					never mulch when the grass is wet (moist grass does   
					not mulch well, and clumps beneath the mower   
					deck).   
					WHAT MOWING PATTERNS TO USE   
					Always start mowing on a smooth, level area.   
					Where possible, make one or two passes around the   
					outside of the area discharging the grass INTO the lawn   
					to keep the cut grass off fences and walks.   
					The size and type of area to be mowed will determine   
					the best mowing pattern to use. Obstructions such as   
					trees, fences and buildings, and conditions such as   
					slopes and grades must also be considered.   
					l Cut long straight strips overlapping slightly.   
					l Where possible, change patterns occasionally to   
					eliminate matting, graining or a corrugated appear-   
					ance.   
					l For a truly professional cut, mow across the lawn in   
					one direction, then recut the lawn by mowing perpen-   
					dicular to the previous cut.   
					Note: Always operate the engine at full throttle when   
					mowing.   
					If you hear the engine slowing down, you are mowing too   
					fast—using a slower ground speed will improve the cut-   
					ting efficiency of the blades and prevents many common   
					cutting problems. Use an appropriate ground speed for   
					the thickness and height of the grass you are cutting (3rd   
					gear or slower for manual gear models). If you hear the   
					engine slowing down you are mowing too fast, use a   
					slower ground speed.   
					The remainder of the mowing should be done in the   
					opposite direction so that the clippings are dispersed   
					OUT onto the area of lawn previously cut.

				Lawn Care & Mowing Information   
					MOWING METHODS   
					Proper Broadcast Mowing   
					Broadcasting, or side-discharging, disperses fine clip-   
					pings evenly over the entire lawn. Many golf courses use   
					this method. Your mower has a deep dish deck to allow   
					freer circulation of clippings so they are broadcast evenly   
					over the lawn.   
					ENGINE SPEED & GROUND SPEED FOR BROADCASTING   
					Always operate the engine at full throttle when mowing.   
					If you hear the engine slowing down, you are mowing too   
					fast—using a slower ground speed will improve the cut-   
					ting efficiency of the blades and prevents many common   
					cutting problems.   
					slowing down you are mowing too fast, use a slower   
					ground speed.   
					HOW MUCH GRASS TO CUT OFF WHEN BROADCASTING   
					ALWAYS use an appropriate ground speed for the thick-   
					ness and height of the grass you are cutting (3rd gear or   
					slower for manual gear models). If you hear the engine   
					Mow when the grass is 3-5 inches long. Do not cut the   
					grass shorter than 2 to 2-1/2 inches. Do not cut off more   
					that 1 inch of grass in a single pass.   
					Proper Mulching   
					Mulching consists of a mower   
					deck which cuts and recuts clip-   
					pings into tiny particles and   
					HOW MUCH GRASS TO MULCH   
					Mulching Action   
					The best mulching action typical-   
					ly results from cutting only the   
					which then blows them down   
					top 1/2 inch to 3/4 inch of grass   
					INTO the lawn. These tiny parti-   
					cles decompose rapidly into by-   
					products your lawn can use.   
					blade. This provides short clip-   
					pings which decompose properly   
					(much more quickly than longer   
					UNDER PROPER CONDI-   
					clippings). The ideal cutting   
					TIONS, your mulching mower will virtually eliminate   
					noticeable clippings on the lawn surface.   
					height will vary with climate, time of year, and quality of   
					your lawn. We recommend that you experiment with both   
					the cutting height and ground speed until you achieve   
					the best cut. Start with a high cutting height and using   
					progressively lower settings until you find a cutting height   
					that is matched to your mowing conditions and prefer-   
					ences.   
					NOTE: When mulching under heavy cutting conditions, a   
					rumbling sound may be present and is normal.   
					MULCHING REQUIRES EXCELLENT MOWING   
					CONDITIONS   
					Mulching mowers cannot function properly if the grass is   
					wet, or if the grass is simply to high to cut. Even more   
					than normal mowing, mulching requires that the grass be   
					dry and the the appropriate amount is cut.   
					Do not use the mower as a mulching mower during the   
					first two or three mowings in the spring. The long grass   
					blades, quick growth, and often wetter conditions are   
					more suitable for broadcasting (side-discharging) or   
					grass bagging operation.   
					ENGINE SPEED & GROUND SPEED FOR BROADCASTING   
					Use full engine throttle matched with a slow ground   
					speed so that clippings will be finely cut. Ground speed   
					while mulching should be HALF of the speed that would   
					be used when broadcasting (side discharging) under   
					similar conditions. Since mulching requires more horse-   
					power than broadcasting, using a slower ground speed is   
					vitally important for proper mulching operation.

					• Reduce the evaporation of water from your lawn.   
					• Provide a cushioning layer to reduce lawn wear.   
					• Moderate soil temperature.   
					TIPS On Dealing With Clippings   
					Clippings are beneficial to your lawn. A common mis-   
					conception about clippings is that they automatically   
					lead to thatch—this is untrue. Short clippings produced   
					by broadcasting and clippings produced by mulching   
					methods actually contribute to a healthy lawn   
					because they:   
					• Clippings act as a safe, non-polluting and inexpen-   
					sive fertilizer that nourishes your lawn. Fresh cut   
					grass blades are 85% water, and are a rich source   
					of nitrogen which is essential to lush growth. And   
					one garbage bag of clippings contains about 1/4 lb.   
					of usable organic nitrogen.   
					COMPOSTING   
					The best way to recycle excess clippings and leave your   
					lawn looking immaculate is to collect them with an effi-   
					cient collection system and deposit them in a compost   
					pile. A compost pile is a collection of grass, leaves, and   
					other organic wastes which—when properly tended—   
					decompose into an odorless, topsoil material. This   
					material, in turn, acts as an inexpensive fertilizer for your   
					lawn and garden.   
					How to start a healthy compost pile:   
					1 Build a bin using bricks, fencing, cement blocks, etc. or pur-   
					chase a prefabricated bin from a garden store. The bin   
					should also have venting on each side and from the bottom   
					to the top.   
					2 Fill the bin with alternating layers of yard waste. Follow this   
					recipe:   
					First layer: 3-4 inches of chopped brush or other coarse   
					material.   
					Second layer: 6-8 inches of mixed leaves, grass clippings,   
					sawdust, etc. Materials should be "sponge damp."   
					Third layer: 1 inch of soil to add micro-organisms that help   
					break down organic matter.   
					Fourth layer: 1-2 inches of manure to provide the nitrogen   
					needed by micro-organisms.   
					Keep adding layers until the bin is almost full. Top off with   
					a 4-6 inch layer of straw and scoop out a "basin" to catch   
					rain water.   
					3 Four or five days later the pile will reach temperatures of   
					140-160 degrees. At this time you'll notice it settling, a   
					good sign your compost is working properly.   
					4 After 5-6 weeks, fork materials into a new pile, turning the   
					outside of the old heap into the center of the new one. Add   
					water if necessary. The compost should be ready to use   
					within three to four months when dark brown, crumbly, and   
					earthy-smelling.
