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.

Avoid Tipping
• Slopes are a major factor related to loss-ofcontrol 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.

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.

• 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.

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.

• 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.

• 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.

Keep Riders Off
• Only allow the operator on the machine. Keep
riders off.

• 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.

• 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 - 7

SAFETY
• On multi-bladed machines, take care as rotating one blade can cause
other blades to rotate.

• 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.

• 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.

• 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.

• 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.

• Wear a suitable protective device such as earplugs. Loud noise can
cause impairment or loss of hearing.

• 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.

Driving Safely on Public Roads

• Do not strike the flywheel with a hammer or hard object because the
flywheel may later shatter during operation.

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.

• 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

• 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.

• Hydraulic hoses and lines can fail due to
physical damage, kinks, age, and exposure.
Check hoses and lines regularly. Replace
damaged hoses and lines.

• 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.

• 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.

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

• 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.

• Keep all nuts and bolts tight, especially blade attachment bolts, to be
sure the equipment is in safe working condition.

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

• Hydraulic fluid connections can loosen due to physical damage and
vibration. Check connections regularly. Tighten loose connections.

• 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 1-800-8228262.

ASSEMBLY
• Always shut off fuel when storing or transporting machine, if the machine
has a fuel shutoff.

to allow you to stand to one side and NOT in front of or over the tire
assembly.

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

• Check tires for low pressure, cuts, bubbles, damaged rims or missing lug
bolts and nuts.

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

Checking Wheel Hardware
• A serious accident could occur causing serious injury if wheel hardware
is not tight.

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.

• 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.

Assembly
Charge and Connect Battery

CAUTION: Avoid injury! The battery produces a flammable
and explosive gas. The battery may explode:
• Do not smoke or have open flame near battery.

• 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.

• Wear eye protection and gloves.

• 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 lockopen device.

• Do not jump start or charge a frozen battery. Warm battery to
16°C (60°F).

• Never check battery charge by placing a metal object across
the posts. Use a voltmeter or hydrometer.

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

1. Remove and discard the tie strap from the positive (+) battery terminal.

• Replace all fuel container caps securely after use.

2. Remove and discard the black protective cap from the negative (–)
battery terminal.

• For gasoline engines, do not use gas with methanol. Methanol is harmful
to your health and to the environment.

3. Charge the battery.
• Battery is fully charged at 12.6 volts.

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

and smother it. Taller grass heights allow mulched leaves to dispense
easier in lawn. Mulch leaves several times if needed.
MX16560
• On Models Without Cruise Control: Use the storage retainer (D) to hold
items such as a garage door opener.

Choosing Mower Blades

• 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.

Three types of mower blades are available for use with LA series mowers.
• 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
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.
• Mow grass often. Short grass clippings will decay quickly.
• Mow with engine at full throttle.
• Adjust travel speed to match mowing conditions:

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.

WARRANTY
applicable U.S. Environmental Protection Agency regulations under 40
CFR Part 90: and,

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 emissionsrelated 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 antismog 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.

• 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.

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.

• John Deere will repair damages to other engine components proximately
caused by a failure under warranty of any emissions-related warranted
part.

Manufacturer’s Warranty Coverage:

• 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 nonexempted add-on or modified part.

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 offroad 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.
