instructions to operate the machine. Know controls  
and how to stop the machine quickly.  
• Watch for traffic when operating near or crossing  
roadways.  
• Do not put hands or feet under mower deck or near  
rotating parts.  
• Use extra care when loading or unloading the  
machine into a trailer or truck. This unit should not  
be driven up or down a ramp onto a trailer or truck  
under power, because the unit could tip over,  
causing serious personal injury. The unit must be  
pushed manually on a ramp to load or unload  
properly.  
• Clear the area of objects such as rocks, toys, wire,  
etc., which could be picked up and thrown by the  
blade. A small object may have been overlooked  
and could be accidentally thrown by the mower in  
any direction and cause injury to you or a  
bystander. To help avoid a thrown objects injury,  
keep children, bystanders and helpers at least 75  
feet from the mower while it is in operation. Always  
wear safety glasses or safety goggles during  
operation or while performing an adjustment or  
repair, to protect eyes from foreign objects. Stop  
the blade(s) when crossing gravel drives, walks or  
roads.  
• Never make a cutting height adjustment while  
engine is running if operator must dismount to do  
so.  
• Wear sturdy, rough-soled work shoes and close-  
fitting slacks and shirts. Do not wear loose fitting  
clothes or jewelry. They can be caught in moving  
parts. Never operate a unit in bare feet, sandals, or  
sneakers.  
• Be sure the area is clear of other people before  
mowing. Stop machine if anyone enters the area.  
• Check overhead clearance carefully before driving  
under power lines, wires, bridges or low hanging  
tree branches, before entering or leaving buildings,  
or in any other situation where the operator may be  
struck or pulled from the unit, which could result in  
serious injury.  
• Never carry passengers.  
• Disengage blade(s) before shifting into reverse and  
backing up. Always look down and behind before  
and while backing.  
• Be aware of the mower and attachment discharge  
direction and do not point it at anyone. Do not  
operate the mower without either the entire grass  
catcher or the chute guard in place.  
• Disengage all attachment clutches, thoroughly  
depress the brake pedal, and shift into neutral  
before attempting to start engine.  
• Your mower is designed to cut normal residential  
grass of a height no more than 10". Do not attempt  
to mow through unusually tall, dry grass (e.g.,  
pasture) or piles of dry leaves. Debris may build up  
on the mower deck or contact the engine exhaust  
presenting a potential fire hazard.  
• Slow down before turning. Operate the machine  
smoothly. Avoid erratic operation and excessive  
speed.  
• Never leave a running machine unattended. Always  
turn off blade(s), place transmission in neutral, set  
park brake, stop engine and remove key before  
dismounting.  
• Turn off blade(s) when not mowing.

• Keep children out of the mowing area and in  
watchful care of an adult other than the operator.  
2. SLOPE OPERATION  
• 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 mow it.  
• Be alert and turn machine off if children enter the  
area.  
• Before and when backing, look behind and down  
for small children.  
• For your safety, use the slope gauge included as  
part of this manual to measure slopes before  
operating this unit on a sloped or hilly area. If the  
slope is greater than 15° as shown on the slope  
gauge, do not operate this unit on that area or  
serious injury could result.  
• Never carry children. They may fall off and be  
seriously injured or interfere with the safe machine  
operation.  
• Never allow children under 14 years old to operate  
the machine. Children 14 years and over should  
only operate machine under close parental  
supervision and proper instruction.  
DO:  
• Use extra care when approaching blind corners,  
shrubs, trees or other objects that may obscure  
your vision of a child or other hazard.  
• Mow up and down slopes, not across.  
• Remove obstacles such as rocks, limbs, etc.  
• Remove key when machine is unattended to  
prevent unauthorized operation.  
• Watch for holes, ruts or bumps. Uneven terrain  
could overturn the machine. Tall grass can hide  
obstacles.  
4. SERVICE  
• Use slow speed. Choose a low enough gear so that  
you will not have to stop or shift while on the slope.  
Always keep machine in gear when going down  
slopes to take advantage of engine braking action.  
• Use extreme care in handling gasoline and other  
fuels. They are extremely flammable and the  
vapors are explosive.  
• Use only an approved container.  
• Follow the manufacturer’s recommendations for  
wheel weights or counterweights to improve  
stability.  
• Never remove fuel cap or add fuel with the engine  
running. Allow engine to cool at least two minutes  
before refueling.  
• Use extra care with grass catchers or other  
attachments. These can change the stability of the  
machine.  
• Replace fuel cap securely and wipe off any spilled  
fuel before starting the engine as it may cause a  
fire or explosion.  
• Keep all movement on the slopes slow and  
gradual. Do not make sudden changes in speed or  
direction. Rapid engagement or braking could  
cause the front of the machine to lift and rapidly flip  
over backwards which could cause serious injury.  
• Extinguish all cigarettes, cigars, pipes and other  
sources of ignition.  
• Never refuel the machine indoors because fuel  
vapors will accumulate in the area.  
• Avoid starting or stopping on a slope. If tires lose  
traction, disengage the blade(s) and proceed slowly  
straight down the slope.  
• Never store the fuel container or machine inside  
where there is an open flame or spark, such as a  
gas hot water heater, space heater or furnace.  
• Never run a machine inside a closed area.  
DO NOT:  
• To reduce fire hazard, keep the machine free of  
grass, leaves or other debris build-up. Clean up oil  
or fuel spillage. Allow machine to cool at least 5  
minutes before storing.  
• Do not turn on slopes unless necessary; then, turn  
slowly and gradually downhill, if possible.  
• Do not mow near drop-offs, ditches or  
embankments.The mower could suddenly turn over  
if a wheel is over the edge of a cliff or ditch, or if an  
edge caves in.  
• Before cleaning, repairing or inspecting, make  
certain the blade and all moving parts have  
stopped. Disconnect the spark plug wire, and keep  
the wire away from the spark plug to prevent  
accidental starting.  
• Do not mow on wet grass. Reduced traction could  
cause sliding.  
• Check the blade and engine mounting bolts at  
frequent intervals for proper tightness. Also,  
visually inspect blade for damage (e.g., excessive  
wear, bent, cracked). Replace with blade which  
meets original equipment specifications.  
• Do not try to stabilize the machine by putting your  
foot on the ground.  
• Do not use grass catcher on steep slopes.  
3. CHILDREN  
• Keep all nuts, bolts and screws tight to be sure the  
equipment is in safe working condition.  
Tragic accidents can occur if the operator is not alert to the  
presence of children. Children are often attracted to the  
machine and the mowing activity. Never assume that chil-  
dren will remain where you last saw them.

• Never tamper with safety devices. Check their proper  
operation regularly. Use all guards as instructed in  
this manual.  
• Do not change the engine governor settings or  
overspeed the engine. Excessive engine speeds are  
dangerous.  
• After striking a foreign object, stop the engine,  
remove the wire from the spark plug and thoroughly  
inspect the mower for any damage. Repair the  
damage before restarting and operating the mower.  
• Observe proper disposal laws and regulations.  
Improper disposal of fluids and materials can harm  
the environment and the ecology.  
• Prior to disposal, determine the proper method to  
dispose of waste from your local Environmental  
Protection Agency. Recycling centers are established  
to properly dispose of materials in an environmentally  
safe fashion.  
• Grass catcher components are subject to wear,  
damage and deterioration, which could expose  
moving parts or allow objects to be thrown. For your  
safety protection, frequently check components and  
replace with manufacturer’s recommended parts  
when necessary.  
• Use proper containers when draining fluids. Do not  
use food or beverage containers that may mislead  
someone into drinking from them. Properly dispose of  
the containers immediately following the draining of  
fluids.  
• Mower blades are sharp and can cut. Wrap the  
blade(s) or wear gloves and use extra caution when  
servicing blade(s).  
• Check brake operation frequently. Adjust and service  
as required.  
• DO NOT pour oil or other fluids into the ground, down  
a drain or into a stream, pond, lake or other body of  
water. Observe Environmental Protection Agency  
regulations when disposing of oil, fuel, coolant, brake  
fluid, filters, batteries, tires and other harmful waste.  
• Muffler, engine and belt guards become hot during  
operation and can cause a burn. Allow to cool down  
before touching.  
WARNING - YOUR RESPONSIBILITY: Restrict the use of this power machine to persons who  
read, understand and follow the warnings and instructions in this manual and on the machine.

DRIVE HANDLES  
The Drive Handles (Left and Right) are located at the top of the Control Tower. (See Figure 8) The drive handles  
are used to move, (propel) steer and stop the Z-series. The drive handles will return toward the neutral position  
without driver input. However, the driver should place the Drive Handles in the neutral position. Unless the Drive  
Handles are placed in the neutral position the Z-Series may creep. When the Drive Handles are in the neutral  
position the unit does not move.

When the engine is running, the throttle is set and the Drive Handles are moved from the neutral position, the unit  
moves in accordance with the driver’s input (push, pull or both). When the driver releases the handles they  
immediately return towards the neutral position and the unit will slow and stop moving (while the engine continues  
to run).  
The rear wheels propel and steer the unit. The Left Drive Handle controls the Left rear wheel and the Right Drive  
handle controls the Right rear wheel. Push a handle forward and the respective wheel turns forward. Pull a handle  
back and the respective wheel turns in reverse.  
Each Drive handle has a range in the forward position (push) and the reverse position (pull). If a Drive Handle is  
moved to the full position (until it stops) the rear wheel turns as fast as the throttle is set. Positions between  
neutral and full are proportional across the range based on the throttle setting. The Drive Handles can be moved  
together in the same direction or independent of each other in any combination (i.e. Left push, Right pull).  
NOTE: The Drive Handles will return toward neutral when released, but they should be placed in neutral by the  
driver. If the Drive Handles are not placed in neutral, the tractor may creep.  
Speed Control  
Bar  
Wing Nut  
Figure 9  
SPEED CONTROL BAR  
The Speed Control Bar is connected to the console with two wing nuts. (See Figure 9). It is used as a grab bar for  
entry or exit from the tractor and allows for pre-set maximum travel speed.  
• Loosen the two wing nuts located on either side of the plastic console.  
• Rotate speed control bar to desire location.  
• Tighten wing nut to secure speed control bar.  
NOTE: Limit loosening the wing nuts to 1 1/2 turns. This will insure proper assembly of the screw not visible on  
the other side of the plastic console. Refer to parts book if screw fell and wing nuts are no longer tightening.  
The Speed Control Bar also aids the drive handles in making “perfect U-turns”. Grasping both Drive Handles and  
the Speed Control Bar at the same time to move forward, release the Left Drive Handle to turn left and then re-  
grasp to continue straight ahead or release the Right Drive Handle to turn right. Refer also to the Quick

QUICK REFERENCE CHART  
The Z-series can turn with a zero radius. The Z-series uses the rear tires to turn. When turning with a zero radius,  
the rear tires are used as the pivot point. A conventional tractor can make a circle but it needs a turning radius,  
usually based on the distance between the front and rear wheels. With a shorter overall length and a zero turn  
radius, the Z-series has excellent maneuverability.  
The Z-series does not have a steering wheel, instead drive handles are used to steer and to propel the unit. When  
the Drive Handles are in the full positions (pull or push) the wheels turn at full speed based on the throttle setting.  
Positions between neutral and full are proportional across the range based on the throttle setting. This is a  
departure from what most of us are accustomed. Please take a few minutes to study the diagrams that follows.

DRIVING THE Z-SERIES  
1. Start the engine and allow it to idle for a moment.  
2. Set the throttle to the fastest position (full open).  
3. Release the Parking Brake by depressing the Parking Brake Pedal.  
4. Gradually provide input by moving the Drive Handles in the desired direction.  
Note: The Z-series speed, while driving, is based on the position of the Drive Handles. Push or pull the handles  
to full for maximum speed and positions in between neutral and full for slower speeds.  
DRIVING ON SLOPES  
Before operating the Z-series on any slope:  
1. Use the Slope Gauge to determine if the slope is safe for operation.  
2. If safe for operation, walk the slope and look for hazards such as rocks, mounds, ruts, stumps or other  
irregularities.  
3. After removing debris and identifying irregularities of the slope, back the Z-series up the steepest slope you  
intend to work. If it cannot negotiate the slope in reverse, the slope is too steep.  
Use the following guidelines when operating on a slope:  
WARNING: Do not mow on inclines with a slope greater than 15 degrees (a rise of approximately  
2-1/2 feet every 10 feet). Slopes greater can cause the Z-series to overturn and cause serious injury.  
• Drive UP and DOWN slopes. Never drive across slopes.  
• Avoid turns. If you must turn, turn down the slope. Turning up a slope greatly increases the chance of roll  
over.  
• Avoid stopping when driving on a slope. If you must stop, start slowly and smoothly to reduce the chance of  
flipping the Z-series over backwards.  
STOPPING THE Z-SERIES  
1. Release pressure on the Drive Handles (guiding them to neutral).  
2. Disengage the PTO (down).  
3. Depress the parking brake and hold.  
4. Push the parking brake handle down. (See Figure 8)  
5. Move the throttle lever to the slowest position (toward turtle).  
6. Turn the Ignition to the OFF position.  
7. Remove the key.  
OPERATING THE PTO (POWER TAKE OFF) CLUTCH  
Note: The operator must remain seated at all times. If the operator leaves the seat without turning off the PTO,  
the engine will automatically shut off.  
NOTE: Be sure lift lever is not in the L position when the PTO is engaged.  
Note: When the Z-series drives in reverse with the PTO engaged (Up), the PTO is automatically disengaged  
(Down).  
1. Sit in the seat and start the engine.  
2. Move the throttle lever to the FAST position (rabbit).  
3. Pull up on the PTO to put it in the RUN position. See Figure 4.

CLEAN THE BATTERY  
Clean the battery by removing it from the unit and washing with a baking soda and water solution. If necessary,  
scrape the battery terminals with a wire brush to remove deposits. Coat terminals and exposed wiring with grease  
or petroleum jelly to prevent corrosion.  
BATTERY STORAGE  
The battery loses some of its charge each day when the unit is not used. Never store battery without a full  
charge. Recharge battery before returning to service or every two months, whichever occurs first. When storing  
unit for extended periods, disconnect battery cables. Removing battery from unit is recommended.  
TIRES  
The two front wheels are caster wheels that are free to swivel to accommodate the direction of the Z-series. The  
tires on the caster wheels are made of solid polyurethane that do not require air.  
The two rear wheels are used to propel the Z-series in the direction of input from the drive handles. Inflation  
pressure of the rear tires is important for stability while the Z-series is in operation. If the tire diameter is not equal  
between the two tires, the Z-series will pull to one side.  
Use the following guidelines for maintaining the tires:  
• Balance inflation pressure between the rear tires to help maintain straight travel (see tire side wall for  
proper inflation pressure).  
• Keep the valve caps in place and tightened to prevent air pressure loss.

2. Run the engine until it begins to falter.  
3. Use the choke to continue operation until all fuel is gone from the carburetor and fuel tank.  
4. Drain any remaining fuel from the fuel line at the carburetor or gas tank.  
WARNING: Drain fuel into an approved container, in open air, and away from open flames.  
Note: Fuel quality deteriorates when fuel is left in engine during warm weather. Poor fuel quality can cause  
engine starting difficulties.  
5. Crank the engine several times to distribute the oil.  
6. Clean the engine and the entire Z-series thoroughly.  
7. Lubricate all lubrication points.  
8. Follow the battery storage guidelines (refer to BATTERY STORAGE for details).  
9. Inflate tires at regular intervals.

SECTION 11: MOWING  
For best results, consider the following recommendations:  
• Mow the first two laps with the discharge pointing toward the center.  
• Mow the next two laps with the discharge pointing outside (away from center) for a balanced cut and  
improved appearance.  
• Do not cut grass too short. The mower tends to "scalp" the grass. Shorter grass invites weeds and will  
yellow quickly in dry conditions.  
During some conditions, the mower may leave streaks of uncut material. Streaking can happen when cutting  
heavy weeds and tall grass. In these conditions it may be necessary to cut the area a second time for a clean cut.  
AVOIDING STREAKING  
1. Mow the area often; cutting grass of shorter lengths helps to avoid streaks.  
2. Operate the Z-series at full throttle and at a slower forward speed.  
3. Maintain sharp blades and replace when worn.  
4. Follow the mowing path shown below. (See Figure 29)
