8. Close fuel shut-off valve, if your machine is equipped.

9. Disconnect the negative battery cable or remove the spark plug wire(s)

(for gasoline engines) before servicing the machine.

Rotating Blades are Dangerous

HELP PREVENT SERIOUS OR FATAL

ACCIDENTS:

• Rotating blades can cut off arms and legs,

and throw objects. Failure to observe safety

instructions could result in serious injury or

death.

• Keep hands, feet and clothing away from mower deck when engine is

running.

• 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.

• 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.

• 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.

• 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.

• 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

machine.

• 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.

• 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.

• Never use the machine as a recreational vehicle or to entertain children.

• 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.

• 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.

• 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.

• Use extreme care when approaching blind corners, shrubs, trees, or

other objects that may block your view of a child.

Avoid Tipping

• 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.

• Mow up and down slopes, not across.

• Watch for holes, ruts, bumps, rocks, or other hidden objects. Uneven

terrain could overturn the machine. Tall grass can hide obstacles.

• Choose a low ground speed so you will not have to stop or shift while on

a slope.

• 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.

• 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.

• 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.

• Use extra care while operating machine with grasscatchers or other

attachments, they can affect stability of the machine. Do not use on steep

slopes.

• 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.

• 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.

Keep Riders Off

• 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.

• Riders obstruct the operator’s view resulting in the machine being

operated in an unsafe manner.

Towing Loads Safely

• Stopping distance increases with speed and weight of towed load. Travel

slowly and allow extra time and distance to stop.

• 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.

• 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.

Safety - 8

SAFETY

• 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.

• Follow the manufacturer’s recommendations for weight limits for towed

equipment and towing on slopes.

• 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.

• Do not shift to neutral and coast downhill.

Wear Appropriate Clothing

• Always wear eye protection when operating

the machine.

• Wear close fitting clothing and safety

equipment appropriate for the job.

• While mowing, always wear substantial footwear and long trousers. Do

not operate the equipment when barefoot or wearing open sandals.

• Wear a suitable protective device such as earplugs. Loud noise can

cause impairment or loss of hearing.

Driving Safely on Public Roads

Avoid personal injury or death resulting from a

collision with another vehicle on public roads:

• Use safety lights and devices. Slow moving

machines when driven on public roads are

hard to see, especially at night.

• 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.

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.

• Keep all nuts and bolts tight, especially blade attachment bolts, to be

sure the equipment is in safe working condition.

• Never tamper with safety devices. Check their proper operation regularly.

• 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.

• 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.

• Check brake operation frequently. Adjust and service as required.

• Maintain or replace safety and instruction labels, as necessary.

• On multi-bladed machines, take care as rotating one blade can cause

other blades to rotate.

• Keep hands, feet, clothing, jewelry, and long hair away from any moving

parts, to prevent them from getting caught.

• 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.

• Securely support any machine elements that must be raised for service

work. Use jack stands or lock service latches to support components

when needed.

• 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.

• Before servicing machine or attachment, carefully release pressure from

any components with stored energy, such as hydraulic components or

springs.

• 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.

• Do not strike the flywheel with a hammer or hard object because the

flywheel may later shatter during operation.

• 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.

Avoid High Pressure Fluids

• Hydraulic hoses and lines can fail due to

physical damage, kinks, age, and exposure.

Check hoses and lines regularly. Replace

damaged hoses and lines.

• Hydraulic fluid connections can loosen due to physical damage and

vibration. Check connections regularly. Tighten loose connections.

• 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.

• Search for leaks with a piece of cardboard. Protect hands and body from

high pressure fluids.

• 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.

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.

• 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.

• Empty any grasscatcher bags or containers completely before storing.

Assembly - 9

ASSEMBLY

• Always shut off fuel when storing or transporting machine, if the machine

has a fuel shutoff.

• Do not store machine near an open flame or source of ignition, such as a

water heater or furnace.

• Check fuel lines, tank, cap, and fittings frequently for cracks or leaks.

Replace if necessary.

Handling Fuel Safely

To avoid personal injury or property

damage, use extreme care in handling fuel.

Fuel is extremely flammable and fuel

vapors are explosive:

• Extinguish all cigarettes, cigars, pipes, and

other sources of ignition.

• 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.

• Never remove the fuel tank cap or add fuel with the engine running. Allow

engine to cool before refueling.

• Never add fuel to or drain fuel from the machine indoors. Move machine

outdoors and provide adequate ventilation.

• 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.

• 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.

• Prevent fire and explosion caused by static electric discharge. Static

electric discharge can ignite fuel vapors in an ungrounded fuel container.

• 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.

• 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

portable container, rather than from a fuel dispenser nozzle.

• 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.

• Never overfill fuel tank. Replace fuel tank cap and tighten securely.

• Replace all fuel container caps securely after use.

• 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:

• Do not attempt to mount a tire without the

proper equipment and experience to perform

the job.

• 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.

• 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.

Checking Wheel Hardware

• A serious accident could occur causing serious injury if wheel hardware

is not tight.

• Check wheel hardware tightness often during the first 100 hours of

operation.

• Wheel hardware must be tightened to specified torque using the proper

procedure anytime it is loosened.

Handling Waste Product and Chemicals

Waste products, such as, used oil, fuel, coolant, brake fluid, and batteries,

can harm the environment and people:

• Do not use beverage containers for waste fluids - someone may drink

from them.

• See your local Recycling Center or authorized dealer to learn how to

recycle or get rid of waste products.

• A Material Safety Data Sheet (MSDS) provides specific details on

chemical products: physical and health hazards, safety procedures, and

emergency response techniques. The seller of the chemical products

used with your machine is responsible for providing the MSDS for that

product.

three wooden blocks.

7. Turn the nut (C) on the front draft arm counterclockwise 1-2 full turns so

that the front of the deck is 3-6 mm (1/8-1/4 in.) lower than the rear. This

adjustment prevents “double cutting,” which wastes horsepower and

causes brown grass tips.

Method Two

NOTE: An optional mower deck leveling gauge (AM130907) is

available from your John Deere dealer. It allows for precision mower

deck leveling by measuring mower deck level at the blade tips.

1. Make sure machine is on a flat, level surface.

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.

• Mow grass often. Short grass clippings will decay quickly.

• Mow with engine at full throttle.

• Adjust travel speed to match mowing conditions:

• Travel at slow speed when you mow thick, tall grass, make sharp turns

or trim around objects.

• 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.).

• Drive over ridges and through shallow ditches straight-on, not at an

angle.

MIF

• 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.

• For Mulching Mower: Shorter cut heights will provide better cut quality,

but may leave noticeable clippings. Higher cut heights will reduce

clippings, but cut quality may decline.

Using Proper Fuel

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.

Always use fresh, clean fuel that is purchased in a quantity that can be

used within approximately 30 days, or add fuel stabilizer.

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.

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.

Keep fuel storage container tightly covered and in a cool area out of direct

sunlight. Fuel can break down and degrade if not sealed properly or

exposed to sun and heat.

Condensation may collect in the fuel tank because of a variety of operating

or environmental conditions and, over time, may affect your machine’s

operation. Fill fuel tank at the end of daily use and store fuel in plastic

containers to reduce condensation.

For best year-round performance and fuel-handling, add stabilizer to fuel

immediately after fuel purchase. Such practice helps prevent engine

performance problems and allows fuel storage in the machine all year

without draining.

Filling Fuel Tank

Fill fuel tank at the end of each day’s operation to prevent condensation

and freezing during cold weather.

1. Park machine safely. (See Parking Safely in the SAFETY section.)

2. Allow engine to cool.

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.

A

c CAUTION: Avoid injury! Fuel vapors are explosive and

flammable:

• Shut engine off before filling fuel tank.

• Allow engine to cool before refueling.

• Do not smoke while handling fuel.

• Keep fuel away from flames or sparks.

• Fill fuel tank outdoors or in well ventilated area.

• Clean up spilled fuel immediately.

• Use clean approved non-metal container to prevent static

electric discharge.

• Use clean approved plastic funnel without screen or filter to

prevent static electric discharge.

IMPORTANT: Avoid damage! Dirt and water in fuel can cause

engine damage:

• Clean dirt and debris from the fuel tank opening.

• Use clean, fresh, stabilized fuel.

• Fill the fuel tank at the end of each day’s 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.

WARRANTY

Warranty

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.

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.

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.

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.

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.

Manufacturer’s 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.

Owner’s Warranty Responsibilities:

• As the small off-road equipment owner, you are responsible for the

performance of the required maintenance listed in your Operator’s

Manual. John Deere recommends that you retain all receipts covering

maintenance on your small off-road engine equipment, but John Deere

can not deny warranty solely for lack of receipts or for your failure to

ensure the performance of all scheduled maintenance.

• As the small off-road engine equipment owner, you should however be

aware that John Deere may deny you warranty coverage if your small off-

road equipment or a part has failed due to abuse, neglect, or improper

maintenance or unapproved modifications.

• You are responsible for presenting your small off-road engine equipment

to an authorized John Deere Commercial and Consumer Equipment

Retailer as soon as a problem exists. The warranty repairs should be

completed in a reasonable amount of time, not to exceed 30 days. If you

have a question regarding your warranty coverage, you should contact

your John Deere Commercial and Consumer Equipment Retailer, or the

John Deere Customer Contact Center at 1-800-537-8233.

General Emissions Warranty Coverage:

The warranty period begins on the date the equipment is delivered to an

ultimate purchaser. John Deere warrants to the ultimate purchaser and

each subsequent purchaser that the small off-road engine equipment is:

• Designed, built and equipped so as to conform to all applicable

regulations adopted by the Air Resources Board;

•Designed, built and equipped so as to conform at the time of sale with

applicable U.S. Environmental Protection Agency regulations under 40

CFR Part 90: and,

• 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.

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.

• Any warranted part that is scheduled only for regular inspection in the

maintenance instructions in the Operator’s Manual is warranted for two

years. A statement in the Operator’s Manual to the effect of “repair or

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.

• 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.

• 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.

• 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.

warranty, reference a copy of the John Deere warranty statement.

Contact your John Deere dealer to obtain a copy.

TO SECURE WARRANTY SERVICE

The purchaser must request warranty service from a John Deere dealer

authorized to sell John Deere batteries, and present the battery to the

dealer with the top cover plate codes intact.

FREE REPLACEMENT

Any new battery which becomes unserviceable (not merely discharged)

due to defects in material or workmanship within 90 days of purchase will

be replaced free of charge. Installation costs will be covered by warranty if

(1) the unserviceable battery was installed by a John Deere factory or

dealer, (2) failure occurs within 90 days of purchase, and (3) the

replacement battery is installed by a John Deere dealer.

PRO RATA ADJUSTMENT

Any new battery which becomes unserviceable (not merely discharged)

due to defects in material or workmanship more than 90 days after

purchase, but before the expiration of the applicable adjustment period,

will be replaced upon payment of the battery’s current list price less a pro

rata credit for unused months of service. The applicable adjustment period

is determined from the Warranty Code printed at the top of the battery and

chart below. Installation costs are not covered by warranty after 90 days

from the date of purchase.

THIS WARRANTY DOES NOT COVER

A. Breakage of the container, cover, or terminals.

B. Depreciation or damage caused by lack of reasonable and necessary

maintenance or by improper maintenance.

C. Transportation, mailing, or service call charges for warranty service.

LIMITATION OF IMPLIED WARRANTIES AND PURCHASER’S

REMEDIES

To the extent permitted by law, neither John Deere nor any company

affiliated with it makes any warranties, representations, or promises as to

the quality, performance or freedom from defect of the products covered

by this warranty. IMPLIED WARRANTIES OF MERCHANTABILITY AND

FITNESS FOR A PARTICULAR PURPOSE, TO THE EXTENT

APPLICABLE, SHALL BE LIMITED IN DURATION TO THE APPLICABLE

ADJUSTMENT PERIOD SET FORTH HERE. THE PURCHASER’S ONLY

REMEDIES IN CONNECTION WITH THE BREACH OR

PERFORMANCE OF ANY WARRANTY ON JOHN DEERE BATTERIES

ARE THOSE SET FORTH HERE. IN NO EVENT WILL THE DEALER,

JOHN DEERE OR ANY COMPANY AFFILIATED WITH JOHN DEERE BE

LIABLE FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES. (Note:

Some states do not allow limitations on how long an implied warranty lasts

or the exclusion or limitation of incidental or consequential damages. So

these limitations and exclusions may not apply to you.) This warranty gives

you specific legal rights, and you may also have some rights which vary

from state to state.

NO DEALER WARRANTY

The selling dealer makes no warranty of it’s own and the dealer has no

authority to make any representation or promise on behalf of John Deere,

or to modify the terms or limitations of this warranty in any way.

PRO RATA MONTHS OF ADJUSTMENT

NOTE: If your battery is not labeled with a warranty code, it is a

warranty code B.
