Rotating Blades are Dangerous  
HELP PREVENT SERIOUS OR FATAL  
ACCIDENTS:  
• If you hit an object or if abnormal vibration occurs, stop the machine and  
inspect it. Make repairs before you operate.  
• Rotating blades can cut off arms and legs,  
and throw objects. Failure to observe safety  
instructions could result in serious injury or  
death.  
• Use only accessories and attachments approved by the manufacturer of  
the machine. Keep safety labels visible when installing accessories and  
attachments.  
• Keep hands, feet and clothing away from mower deck when engine is  
running.  
• Do not wear radio or music headphones. Safe service and operation  
requires your full attention.  
• Be alert at all times, drive forward and in reverse carefully. People,  
especially children can move quickly into the mowing area before you  
know it.  
• When machine is left unattended, stored, or parked, lower the mower  
deck unless a positive mechanical lock is used.  
Using a Spark Arrestor  
The engine in this machine is not equipped with a spark arrestor muffler.  
The California Public Resources Code, section 4442.5 provides as  
follows:  
• Before backing up, stop mower blades or attachments and look down  
and behind the machine carefully, especially for children.  
• Do not mow in reverse.  
• Shut off blades when you are not mowing.  
No person shall sell, offer for sale, lease, or rent to any person any internal  
combustion engine subject to Section 4442 or 4443, and not subject to  
Section 13005 of the Health and Safety Code, unless the person provides  
a written notice to the purchaser or bailee, at the time of sale or at the time  
of entering into the lease or rental contract, stating that it is a violation of  
Section 4442 or 4443 to use or operate the engine on any forest-covered,  
brush-covered, or grass-covered land unless the engine is equipped with  
a spark arrestor, as defined in Section 4442, maintained in effective  
working order or the engine is constructed, equipped, and maintained for  
the prevention of fire pursuant to Section 4443. Cal. Pub. Res. Code  
4442.5.  
• Park machine safely before leaving the operator’s station for any reason  
including emptying the grasscatchers or unplugging the chute.  
• The mower blades should stop in approximately five seconds when the  
mower is disengaged. If you believe that your blades may not be stopping  
in that period of time, take your machine to your authorized dealer where  
they can safely check and service your machine.  
Protect Children  
• Death or serious injury can  
occur when young children  
associate having fun with a lawn  
mowing machine simply because  
someone has given them a ride  
on a machine.  
Other states or jurisdictions may have similar laws. A spark arrestor for  
your machine may be available from your authorized dealer. An installed  
spark arrestor must be maintained in good working order by the operator.  
Checking Mowing Area  
• Children are attracted to lawn mowing machines and mowing activities.  
They don’t understand the dangers of rotating blades or the fact that the  
operator is unaware of their presence.  
• Clear mowing area of objects that might be  
thrown. Keep people and pets out of mowing  
area.  
• Children who have been given rides in the past may suddenly appear in  
the mowing area for another ride and be run over or backed over by the

SAFETY  
machine.  
Keep Riders Off  
Tragic accidents with children can occur if the operator is not alert to the  
presence of children, especially when a child approaches a machine from  
behind. Before and while backing up, stop mower blades and look down  
and behind the machine carefully, especially for children.  
• Only allow the operator on the machine. Keep  
riders off.  
• Riders on the machine or attachment may be  
struck by foreign objects or thrown off the  
machine causing serious injury.  
• Never carry children on a machine or attachment, even with the blades  
off. Do not tow children in a cart or trailer. They can fall off and be seriously  
injured or interfere with safe machine operation.  
• Riders obstruct the operator’s view resulting in the machine being  
operated in an unsafe manner.  
• Never use the machine as a recreational vehicle or to entertain children.  
Towing Loads Safely  
• Never allow children or an untrained person operate the machine.  
Instruct all operators not to give children a ride on the machine or in an  
attachment.  
• Stopping distance increases with speed and weight of towed load. Travel  
slowly and allow extra time and distance to stop.  
• Keep children indoors, out of the mowing area, and in the watchful eye of  
a responsible adult, other than the operator, when a mower is being  
operated.  
Total towed weight must not exceed combined weight of pulling machine,  
ballast and operator. Use counterweights or wheel weights as described in  
the attachment or pulling machine operator’s manual.  
• Stay alert to the presence of children. Never assume that children will  
remain where you last saw them. Turn the machine off if a child enters the  
work area.  
• Excessive towed load can cause loss of traction and loss of control on  
slopes. Reduce towed weight when operating on slopes.  
• Never allow children or others in or on towed equipment.  
• Use extreme care when approaching blind corners, shrubs, trees, or  
other objects that may block your view of a child.  
• Use only approved hitches. Tow only with a machine that has a hitch  
designed for towing. Do not attach towed equipment except at the  
approved hitch point.  
Avoid Tipping  
• Follow the manufacturer’s recommendations for weight limits for towed  
equipment and towing on slopes.  
• Slopes are a major factor related to loss-of-  
control and tip-over accidents, which can result  
in severe injury or death. Operation on all  
slopes requires extra caution. If you cannot  
back up the slope or if you feel uneasy on it, do  
not mow it.  
• If you cannot back up a slope with a towed load, the slope is too steep to  
operate on with the towed load. Reduce the towed load or do not operate.  
• Do not turn sharply. Use additional caution when turning or operating  
under adverse surface conditions. Use care when reversing.  
• Mow up and down slopes, not across.  
• Do not shift to neutral and coast downhill.  
• Watch for holes, ruts, bumps, rocks, or other hidden objects. Uneven  
terrain could overturn the machine. Tall grass can hide obstacles.  
Wear Appropriate Clothing  
• Choose a low ground speed so you will not have to stop or shift while on  
a slope.  
• Always wear eye protection when operating  
the machine.  
• Do not mow or operate machine on wet grass. Tires may lose traction.  
Tires may lose traction on slopes even though the brakes are functioning  
properly.  
• Wear close fitting clothing and safety  
equipment appropriate for the job.  
• While operating this machine, always wear substantial footwear and long  
trousers. Do not operate the equipment when barefoot or wearing open  
sandals.  
• Always keep the machine in gear when going down slopes. Do not shift  
to neutral and coast downhill.  
• Avoid starting, stopping or turning on a slope. If the tires lose traction,  
disengage the blades and proceed slowly, straight down the slope.  
• Wear a suitable protective device such as earplugs. Loud noise can  
cause impairment or loss of hearing.  
• Keep all movement on slopes slow and gradual. Do not make sudden  
changes in speed or direction, which could cause the machine to roll over.  
Driving Safely on Public Roads  
Avoid personal injury or death resulting from a  
collision with another vehicle on public roads:  
• Use extra care while operating machine with grasscatchers or other  
attachments, they can affect stability of the machine. Do not use on steep  
slopes.  
• Use safety lights and devices. Slow moving  
machines when driven on public roads are  
hard to see, especially at night.  
• Do not try to stabilize the machine by putting your foot on the ground.  
• Do not mow near drop-offs, ditches, embankments, or bodies of water.  
The machine could suddenly roll over if a wheel goes over the edge or the  
edge caves in. Leave a safety area between the machine and any hazard.  
• Whenever driving on public roads, use flashing warning lights and turn  
signals according to local regulations. Extra flashing warning lights may  
need to be installed.  
• Follow the manufacturer’s recommendations for wheel weights or  
counterweights for added stability when operating on slopes or using front  
or rear mounted attachments. Remove weights when not required.  
Practice Safe Maintenance  
• Only qualified, trained adults should service  
this machine. Understand service procedure  
before doing work.  
• Never operate machine in a closed area  
where dangerous carbon monoxide fumes can collect.  
Safety - 7  
SAFETY  
• Keep all nuts and bolts tight, especially blade attachment bolts, to be  
sure the equipment is in safe working condition.  
• Search for leaks with a piece of cardboard. Protect hands and body from  
high pressure fluids.  
• Never tamper with safety devices. Check their proper operation regularly.  
• If an accident occurs, see a doctor immediately. Any fluid injected into  
the skin must be surgically removed within a few hours or gangrene may  
result. Doctors unfamiliar with this type of injury should reference a  
knowledgeable medical source. Such information is available from Deere  
& Company Medical Department in Moline, Illinois, U.S.A. Information may  
be obtained in the United States and Canada only by calling 1-800-822-  
8262.  
• Keep machine free of grass, leaves or other debris build-up. Clean up oil  
or fuel spillage and remove any fuel-soaked debris. Allow the machine to  
cool before storing.  
• If you strike a foreign object, stop and inspect the machine. Repair, if  
necessary, before restarting.  
• Never make any adjustments or repairs with the engine running. Wait for  
all movement to stop on machine before adjusting, cleaning or repairing.  
Prevent Fires  
• Machine fires and structure fires can occur if a  
machine is stored before allowing it to cool, if  
debris is not removed from critical areas of the  
machine, or if machine is stored near  
combustible materials.  
• Check grasscatcher components and the discharge guard frequently and  
replace with manufacturer’s recommended parts, when necessary.  
Grasscatcher components are subject to wear, damage, and deterioration  
which could expose moving parts or allow objects to be thrown.  
• Mower blades are sharp. Wrap the blade or wear gloves, and use extra  
care when servicing them. Only replace blades. Never straighten or weld  
them.  
• Remove grass and debris completely from  
engine compartment and muffler area, and from  
on top of the mower deck, before and after operating machine, especially  
after mowing or mulching in dry conditions.  
• Check brake operation frequently. Adjust and service as required.  
• Maintain or replace safety and instruction labels, as necessary.  
• Empty any grasscatcher bags or containers completely before storing.  
• On multi-bladed machines, take care as rotating one blade can cause  
other blades to rotate.  
• Always shut off fuel when storing or transporting machine, if the machine  
has a fuel shutoff.  
• Keep hands, feet, clothing, jewelry, and long hair away from any moving  
parts, to prevent them from getting caught.  
• Do not store machine near an open flame or source of ignition, such as a  
water heater or furnace.  
• Lower any attachments to the ground before cleaning or servicing  
machine. Disengage all power and stop the engine. Lock park brake and  
remove the key. Let machine cool.  
• Check fuel lines, tank, cap, and fittings frequently for cracks or leaks.  
Replace if necessary.  
Handling Fuel Safely  
• Securely support any machine elements that must be raised for service  
work. Use jack stands or lock service latches to support components  
when needed.  
To avoid personal injury or property  
damage, use extreme care in handling fuel.  
Fuel is extremely flammable and fuel  
vapors are explosive:  
• Disconnect battery or remove spark plug wire (for gasoline engines)  
before making any repairs. Disconnect negative terminal first and positive  
last. Install positive terminal first and negative last.  
• Extinguish all cigarettes, cigars, pipes, and  
other sources of ignition.  
• Before servicing machine or attachment, carefully release pressure from  
any components with stored energy, such as hydraulic components or  
springs.  
• Use only an approved fuel container. Use  
only non-metal, portable fuel containers  
approved by the Underwriter’s Laboratory  
(U.L.) or the American Society for Testing &  
Materials (ASTM). If using a funnel, make sure  
it is plastic and has no screen or filter.  
• Keep all parts in good condition and properly installed. Fix damage  
immediately. Replace worn or broken parts.  
• Charge batteries in an open, well-ventilated area, away from sparks.  
Unplug battery charger before connecting or disconnecting from the  
battery. Wear protective clothing and use insulated tools.  
• Never remove the fuel tank cap or add fuel with the engine running. Allow  
engine to cool before refueling.  
• Do not strike the flywheel with a hammer or hard object because the  
flywheel may later shatter during operation.  
• Never add fuel to or drain fuel from the machine indoors. Move machine  
outdoors and provide adequate ventilation.  
• If equipped with hydraulic lift - release hydraulic pressure by lowering  
attachment or cutting units to the ground or to a mechanical stop and  
move hydraulic control levers back and forth.  
• Clean up spilled fuel immediately. If fuel is spilled on clothing, change  
clothing immediately. If fuel is spilled near machine, do not attempt to start  
the engine but move the machine away from the area of spillage. Avoid  
creating any source of ignition until fuel vapors have dissipated.  
Avoid High Pressure Fluids  
• Never store the machine or fuel container where there is an open flame,  
spark, or pilot light such as on a water heater or other appliance.  
• Hydraulic hoses and lines can fail due to  
physical damage, kinks, age, and exposure.  
Check hoses and lines regularly. Replace  
damaged hoses and lines.  
• Prevent fire and explosion caused by static electric discharge. Static  
electric discharge can ignite fuel vapors in an ungrounded fuel container.  
• Hydraulic fluid connections can loosen due to physical damage and  
vibration. Check connections regularly. Tighten loose connections.  
• Never fill containers inside a vehicle or on a truck or trailer bed with a  
plastic liner. Always place containers on the ground away from your  
vehicle before fueling.  
• Escaping fluid under pressure can penetrate the skin causing serious  
injury. Avoid the hazard by relieving pressure before disconnecting  
hydraulic or other lines. Tighten all connections before applying pressure.  
• Remove fuel-powered equipment from the truck or trailer and refuel it on  
the ground. If this is not possible, then refuel such equipment with a

Assembly  
• Keep the nozzle in contact with the rim of the fuel tank or container  
opening at all times until the fueling is complete. Do not use a nozzle lock-  
open device.  
Charge and Connect Battery  
• Never overfill fuel tank. Replace fuel tank cap and tighten securely.  
• Replace all fuel container caps securely after use.  
c
CAUTION: Avoid injury! The battery produces a flammable  
and explosive gas. The battery may explode:  
Do not smoke or have open flame near battery.  
Wear eye protection and gloves.  
• For gasoline engines, do not use gas with methanol. Methanol is harmful  
to your health and to the environment.  
Tire Safety  
Explosive separation of a tire and rim parts  
can cause serious injury or death:  
Never check battery charge by placing a metal object across  
the posts. Use a voltmeter or hydrometer.  
Do not jump start or charge a frozen battery. Warm battery to  
16°C (60°F).  
• Do not attempt to mount a tire without the  
proper equipment and experience to perform  
the job.  
1. Remove and discard the tie strap from the positive (+) battery terminal.  
• Always maintain the correct tire pressure. Do not inflate the tires above  
the recommended pressure. Never weld or heat a wheel and tire  
assembly. The heat can cause an increase in air pressure resulting in a  
tire explosion. Welding can structurally weaken or deform the wheel.  
2. Remove and discard the black protective cap from the negative (–)  
battery terminal.  
3. Charge the battery.  
• Battery is fully charged at 12.6 volts.  
• When inflating tires, use a clip-on chuck and extension hose long enough  
to allow you to stand to one side and NOT in front of or over the tire  
assembly.  
• Check tires for low pressure, cuts, bubbles, damaged rims or missing lug  
bolts and nuts.

OPERATING  
Using Accessories  
Choosing Mower Blades  
Three types of mower blades are available for use with D series mowers.  
B
• 3-N-1 blades. These are general purpose blades that are best suited for  
side-discharge operation, but can be used with a bagger attachment, or  
with a mulch cover installed. They are not designed for optimal  
performance when bagging or mulching.  
• Bagger blades. These blades are designed for optimal performance  
when used with bagger attachments.  
• Mulching blades. These blades are designed for optimal performance  
when used with a mulch cover installed.  
Mowing Tips  
A
The following recommendations will produce the best lawn cut quality and  
appearance:  
• Keep mower blades sharp. Dull blades will tear grass; tips of grass will  
then turn brown.  
• Cutting grass too short may kill grass and let weeds grow easily. The  
suggested finished cut height range is 44 - 70 mm (1.75 - 2.75 in.).  
• Adjust cutting height to remove only 1/3 of the grass at a time.  
• Do not mow wet grass.  
B
• Mow grass often. Short grass clippings will decay quickly.  
• Mow with engine at full throttle.  
MX46479  
Using the Power Port (If Equipped)  
• Adjust travel speed to match mowing conditions:  
Travel at slow speed when you mow thick, tall grass, make sharp turns  
or trim around objects.  
c
CAUTION: Avoid injury! Safe operation requires your full  
attention. Do not wear radio or music headphones while operating  
machine.  
Travel at moderate speed when you mow thin grass.  
• Use a different mowing pattern each time you mow. Overlap mowing  
paths 50 - 100 mm (2 - 4 in.).  
An electric power port (A) can be used for accessories. See your  
authorized dealer.  
• Drive over ridges and through shallow ditches straight-on, not at an  
angle.  
Using CargO Mount System™  
The front and rear CargO Mount System™ brackets (B) can be used for  
easy attachment of selected optional equipment.  
Use John Deere approved optional equipment only. See your Authorized  
Service Center for approved optional equipment.  
Using Storage Accessories  
MIF  
C
• Mow around the outside twice, then mow inside in straight passes. Best  
cut is achieved when mowing in a straight line.  
• When mowing or mulching near pavement, overlap the pavement by 50  
mm (2 in.) to allow clippings to dispense over grass.  
• A thick layer of mulched leaves can prevent sunlight from getting to grass  
and smother it. Taller grass heights allow mulched leaves to dispense  
easier in lawn. Mulch leaves several times if needed.  
• Use a thatcher in late spring or summer to pull up dead grass and aerate  
ground.  
MX46942  
• On Models Without Cruise Control: Use the storage retainer (C) to hold  
items such as a garage door opener.  
• For Mulching Mower: Shorter cut heights will provide better cut quality,  
but may leave noticeable clippings. Higher cut heights will reduce

3. Pull defective fuse (A) out of socket.  
Clean dirt and debris from the fuel tank opening.  
4. Check metal clip in fuse window and discard fuse if clip is broken.  
5. Push new 20 amp fuse into socket.  
6. Lower hood.  
Use clean, fresh, stabilized fuel.  
Fill the fuel tank at the end of each days operation to keep  
condensation out of the fuel tank.  
Use a non-metallic funnel with a plastic mesh strainer when  
filling the fuel tank or container.  
Service Miscellaneous  
Fill fuel tank at the end of each day’s operation to prevent condensation  
and freezing during cold weather.  
Using Proper Fuel and Stabilizer  
1. Park machine safely. (See Parking Safely in the SAFETY section.)  
2. Allow engine to cool.  
IMPORTANT: Avoid damage! Using stale, contaminated or  
improper fuel can result in engine and fuel system damage.  
Repairs caused by stale, contaminated or improper fuel are not  
covered by warranty.  
3. Remove any trash from area around fuel tank cap.  
4. Remove fuel tank cap slowly to allow any pressure built up in tank to  
escape.  
Use regular grade unleaded fuel with an octane rating of 87 octane or  
higher. Fuel blends containing up to 10% ethanol or up to 15% MTBE  
reformulated fuel are acceptable. Do not use fuel or additives containing  
methanol as engine damage can occur.  
5. Fill fuel tank only to bottom of filler neck. Do not overfill.  
6. Do not continue to “top off” the tank once full.  
7. Install fuel tank cap, and turn cap until it clicks.  
Always use fresh, clean fuel that is purchased in a quantity that can be  
used within approximately 30 days. Fuel stabilizer should always be added  
to the fuel each time fuel is purchased. Add stabilizer before filling the fuel  
container to insure proper mixing. Such practice helps prevent engine  
performance problems and allows fuel storage in the machine all year  
without draining.  
Checking Tire Pressure  
1. Check tires for damage.  
2. Check tire pressure with an accurate gauge.  
3. Service tires safely. (See Tire Safety in the SAFETY section.)  
Store fuel in plastic containers to reduce condensation. Make sure the cap  
on the fuel container is tight to reduce fuel contamination and evaporation.  
For best fuel storage life, use a self-sealing gas can.  
4. Check that tires have equal air pressure. Add or remove air, if  
necessary.  
Fuel is blended to give best seasonal performance. To avoid engine  
performance problems such as hard starting or vapor lock, use in-season  
fuel. Use fuel during warm weather that was purchased during that  
season, and use fuel during cold weather that was purchased during that  
season.  
5. Refer to side of tire for correct tire inflation pressure.  
Removing and Installing Hood  
Removing  
Fuel can become stale in machines with engines that are used seasonally  
or infrequently during a season. Stale fuel can produce varnish and plug  
carburetor components which can affect engine performance.

WARRANTY  
applicable U.S. Environmental Protection Agency regulations under 40  
CFR Part 90: and,  
Warranty  
• Free from defects in materials and workmanship which cause such  
engine to fail to conform with applicable regulations for a period of two  
years of engine use from the date of sale to the ultimate purchaser.  
Product Warranty  
Product warranty is provided as part of John Deere’s support program for  
customers who operate and maintain their equipment as described in this  
manual.  
Emissions Warranty Interpretation  
• Any warranted part that is not scheduled for replacement as required by  
the maintenance instructions in the Operator’s Manual is warranted for two  
years. If any such part fails during the period of warranty coverage it will  
be repaired or replaced by John Deere. Any such part repaired or  
replaced under warranty is warranted for the remaining warranty period.  
Engine related warranties stated in this manual refer only to emissions-  
related parts and components of your engine. The complete engine  
warranty, less emission-related parts and components, is provided  
separately as the Limited Warranty for New John Deere Commercial &  
Consumer Equipment.  
• Any warranted part that is scheduled only for regular inspection in the  
maintenance instructions in the Operator’s Manual is warranted for two

replace as necessary” does not reduce the period of warranty coverage.  
Any such part repaired or replaced under warranty is warranted for the  
remaining warranty period.  
California and U.S. EPA Emissions Control System  
Warranty Statement (Small Off-Road Gas Engines)  
Your Warranty Rights and Obligations  
The California Air Resources Board, John Deere, and the United States  
Environmental Protection Agency are pleased to explain the emissions  
control system’s warranty on your 2009 and later small off-road engine  
equipment. In California, new equipment that uses small off-road engines  
must be designed, built and equipped to meet the State’s stringent anti-  
smog standards. John Deere must warrant the emissions control system  
on your small off-road engine equipment for the period listed below  
provided there has been no abuse, neglect or improper maintenance of  
your equipment.  
• Any warranted part that is scheduled for replacement as required  
maintenance in the Operator’s Manual is warranted for the period of time  
prior to the first scheduled replacement point for that part. If the part fails  
prior to the first scheduled replacement, the part will be repaired or  
replaced by John Deere. Any such part repaired or replaced under  
warranty is warranted for the remainder of the period prior to the first  
scheduled replacement point for the part.  
• Repair or replacement of any warranted part under the warranty will be  
performed at no charge to the owner at any authorized John Deere  
Commercial and Consumer Equipment Retailer.  
Your emissions control system may include parts such as: carburetors or  
fuel-injection system, ignition system, catalytic converters, fuel tanks,  
valves, filters, clamps, connectors, and other associated components.  
Also, included may be hoses, belts, sensors and other emission-related  
assemblies.  
• The owner will not be charged for diagnostic labor which leads to the  
determination that a warranted part is defective, provided such work is  
performed by John Deere.  
• John Deere will repair damages to other engine components proximately  
caused by a failure under warranty of any emissions-related warranted  
part.  
Where a warrantable condition exists, John Deere will repair your small  
off-road engine equipment at no cost to you including diagnosis, parts and  
labor.  
• Add-on or modified parts that are not exempted by the Air Resources  
Board may not be used. The use of any non-exempted add-on or modified  
parts will be grounds for disallowing a warranty claim. John Deere will not  
be liable to warrant failures of warranted parts caused by the use of a non-  
exempted add-on or modified part.  
Manufacturers Warranty Coverage:  
This emissions control system is warranted for two years. If any emissions  
related part on your equipment is defective, the part will be repaired or  
replaced by John Deere.
