keep bystanders, helpers, children and pets at least 75 feet
from the machine while it is in operation. Stop machine if
anyone enters the area.
6.
Thoroughly inspect the area where the equipment is to be
used. Remove all stones, sticks, wire, bones, toys, and other
foreign objects which could be picked up and thrown by
the blade(s). Thrown objects can cause serious personal
injury.
7.
Plan your mowing pattern to avoid discharge of material
toward roads, sidewalks, bystanders and the like. Also,
avoid discharging material against a wall or obstruction
which may cause discharged material to ricochet back
toward the operator.
8.
Always wear safety glasses or safety goggles during
operation and while performing an adjustment or repair
to protect your eyes. Thrown objects which ricochet can
cause serious injury to the eyes.
9.
Wear sturdy, rough-soled work shoes and close-fitting
slacks and shirts. Loose fitting clothes and jewelry can be
caught in movable parts. Never operate this machine in
bare feet or sandals.
10.
Be aware of the mower and attachment discharge direction
and do not point it at anyone. Do not operate the mower
without the discharge cover or entire grass catcher in its
proper place.
11.
Do not put hands or feet near rotating parts or under the
cutting deck. Contact with the blade(s) can amputate
hands and feet.
3
12. A missing or damaged discharge cover can cause blade
contact or thrown object injuries.
13.
Stop the blade(s) when crossing gravel drives, walks, or
roads and while not cutting grass.
14. Watch for traffic when operating near or crossing
roadways. This machine is not intended for use on any
public roadway.
15.
Do not operate the machine while under the influence of
alcohol or drugs.
16. Mow only in daylight or good artificial light.
17.
Never carry passengers.
18. Disengage blade(s) before shifting into reverse. Back up
slowly. Always look down and behind before and while
backing to avoid a back-over accident.
19.
Slow down before turning. Operate the machine smoothly.
Avoid erratic operation and excessive speed.
20.
Disengage blade(s), set parking brake, stop engine and wait
until the blade(s) come to a complete stop before removing
grass catcher, emptying grass, unclogging chute, removing
any grass or debris, or making any adjustments.
21.
Never leave a running machine unattended. Always turn
off blade(s), place transmission in neutral, set parking
brake, stop engine and remove key before dismounting.
22. Use extra care when loading or unloading the machine into
a trailer or truck. This machine should not be driven up or
down ramp(s), because the machine could tip over, causing
serious personal injury. The machine must be pushed
manually on ramp(s) to load or unload properly.
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.
For your safety, use the slope gauge included as part of this
manual to measure slopes before operating this machine on
a sloped or hilly area. If the slope is greater than 15 degrees as
shown on the slope gauge, do not operate this machine on that
area or serious injury could result.
Do:
1.
Mow up and down slopes, not across. Exercise extreme
caution when changing direction on slopes.
2.
Watch for holes, ruts, bumps, rocks, or other hidden
objects. Uneven terrain could overturn the machine. Tall
grass can hide obstacles.
3.
Use slow speed. Choose a low enough speed setting so
that you will not have to stop or shift while on the slope.
Tires may lose traction on slopes even though the brakes
are functioning properly. Always keep machine in gear
when going down slopes to take advantage of engine
braking action.
4.
Follow the manufacturer’s recommendations for wheel
weights or counterweights to improve stability.
5.
Use extra care with grass catchers or other attachments.
These can change the stability of the machine.
6.
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.
7.
Avoid starting or stopping on a slope. If tires lose traction,
disengage the blade(s) and proceed slowly straight down
the slope.
23. Muffler and engine become hot and can cause a burn. Do
not touch.
24. Check overhead clearances carefully before driving under
low hanging tree branches, wires, door openings etc.,
where the operator may be struck or pulled from the
machine, which could result in serious injury.
25. Disengage all attachment clutches, depress the brake
pedal completely and shift into neutral before attempting
to start engine.
26. Your machine 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.
Dry grass or leaves may contact the engine exhaust and/
or build up on the mower deck presenting a potential fire
hazard.
27.
Use only accessories and attachments approved for this
machine by the machine manufacturer. Read, understand
and follow all instructions provided with the approved
accessory or attachment.
28. Data indicates that operators, age 60 years and above, are
involved in a large percentage of riding mower-related
injuries. These operators should evaluate their ability
to operate the riding mower safely enough to protect
themselves and others from serious injury.
29.

If situations occur which are not covered in this manual, use
care and good judgment. Contact your customer service
representative for assistance.
Section 2 — Important Safe Operation Practices
Do Not:
1.
Do not turn on slopes unless necessary; then, turn slowly
and gradually downhill, if possible.
2.
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, ditch, or if an edge caves in.
3.
Do not try to stabilize the machine by putting your foot on
the ground.
4.
Do not use a grass catcher on steep slopes.
5.
Do not mow on wet grass. Reduced traction could cause
sliding.
6.
Do not shift to neutral and coast downhill. Over-speeding
may cause the operator to lose control of the machine
resulting in serious injury or death.
7.
Do not tow heavy pull behind attachments (e.g. loaded
dump cart, lawn roller, etc.) on slopes greater than 5
degrees. When going down hill, the extra weight tends
to push the tractor and may cause you to loose control
(e.g. tractor may speed up, braking and steering ability are
reduced, attachment may jack-knife and cause tractor to
overturn).
Children
Service
1.
Safe Handling of Gasoline:
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. They do not understand
the dangers. Never assume that children will remain where
you last saw them.
a.
Keep children out of the mowing area and in
watchful care of a responsible adult other than the
operator.
b.
Be alert and turn machine off if a child enters the
area.
c.
Before and while backing, look behind and down for
small children.
d.
Never carry children, even with the blade(s) shut off.
They may fall off and be seriously injured or interfere
with safe machine operation.
e.
Use extreme care when approaching blind corners,
doorways, shrubs, trees or other objects that may
block your vision of a child who may run into the
path of the machine.
f.
2.
1.
To avoid back-over accidents, always disengage
the cutting blade(s) before shifting into Reverse.
If equipped, the “Reverse Caution Mode” should
not be used when children or others are around.
g.
Keep children away from hot or running engines.
They can suffer burns from a hot muffler.
h.
Remove key when machine is unattended to
prevent unauthorized operation.
Never allow children under 14 years of age to operate this
machine. Children 14 and over should read and understand
the instructions and safe operation practices in this manual
and on the machine and should be trained and supervised
by an adult.
To avoid personal injury or property damage use extreme
care in handling gasoline. Gasoline is extremely
flammable and the vapors are explosive. Serious
personal injury can occur when gasoline is spilled on
yourself or your clothes which can ignite. Wash your skin
and change clothes immediately.
a.
Use only an approved gasoline container.
b.
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 filling.
c.
When practical, remove gas-powered equipment
from the truck or trailer and refuel it on the ground.
If this is not possible, then refuel such equipment on
a trailer with a portable container, rather than from a
gasoline dispenser nozzle.
d.
Keep the nozzle in contact with the rim of the fuel
tank or container opening at all times until fueling is
complete. Do not use a nozzle lock-open device.
e.
Extinguish all cigarettes, cigars, pipes and other
sources of ignition.
f.
Never fuel machine indoors.
g.
Never remove gas cap or add fuel while the engine
is hot or running. Allow engine to cool at least two
minutes before refueling.
h.
Never over fill fuel tank. Fill tank to no more than ½
inch below bottom of filler neck to allow space for
fuel expansion.
i.
Replace gasoline cap and tighten securely.
j.
If gasoline is spilled, wipe it off the engine and
equipment. Move machine to another area. Wait 5
minutes before starting the engine.
Towing
1.
Tow only with a machine that has a hitch designed for
towing. Do not attach towed equipment except at the
hitch point.
k.
2.
Follow the manufacturers recommendation for weight
limits for towed equipment and towing on slopes.
To reduce fire hazards, keep machine free of grass,
leaves, or other debris build-up. Clean up oil or fuel
spillage and remove any fuel soaked debris.
l.
3.
Never allow children or others in or on towed equipment.
4.
On slopes, the weight of the towed equipment may cause
loss of traction and loss of control.
Never store the machine or fuel container inside
where there is an open flame, spark or pilot light
as on a water heater, space heater, furnace, clothes
dryer or other gas appliances.
5.
Always use extra caution when towing with a machine
capable of making tight turns (e.g. “zero-turn” ride-on
mower). Make wide turns to avoid jack-knifing.
General Service
6.
Travel slowly and allow extra distance to stop.
1.
7.
Do not shift to neutral and coast downhill.
Never run an engine indoors or in a poorly ventilated area.
Engine exhaust contains carbon monoxide, an odorless,
and deadly gas.
2.
Before cleaning, repairing, or inspecting, make certain the
blade(s) and all moving parts have stopped. Disconnect the
spark plug wire and ground against the engine to prevent
unintended starting.
m. Allow a machine to cool at least five minutes before
storing.
Section 2 — Important Safe Operation Practices

Mowing
WARNING! To help avoid blade contact or a
thrown object injury, keep bystanders, helpers,
children and pets at least 75 feet from the machine
while it is in operation. Stop machine if anyone
enters the area.
The following information will be helpful when using the cutting
deck with your tractor:
WARNING! Plan your mowing pattern to avoid
discharge of materials toward roads, sidewalks,
bystanders and the like. Also, avoid discharging
material against a wall or obstruction which may
cause discharged material to ricochet back toward
the operator.
•
Do not mow at high ground speed, especially if a mulch kit
or grass collector is installed.
•
For best results it is recommended that the first two laps be
cut with the discharge thrown towards the center. After the
first two laps, reverse the direction to throw the discharge
to the outside for the balance of cutting. This will give a
better appearance to the lawn.
•
Do not cut the grass too short. Short grass invites weed
growth and yellows quickly in dry weather.
•
Mowing should always be done with the engine at full
throttle.
•
Under heavier conditions it may be necessary to go back
over the cut area a second time to get a clean cut.
•
Do NOT attempt to mow heavy brush and weeds and
extremely tall grass. Your tractor is designed to mow lawns,
NOT clear brush.
•
Keep the blades sharp and replace the blades when worn.
Refer to Cutting Blades in the Service section of this manual
for proper blade sharpening instructions.

FEDERAL and/or CALIFORNIA EMISSION CONTROL WARRANTY STATEMENT
YOUR WARRANTY RIGHTS AND OBLIGATIONS
MTD Consumer Group Inc, the United States Environmental Protection Agency (EPA), and for those products certified for sale in the state of
California, the California Air Resources Board (CARB) are pleased to explain the evaporative emission control system (ECS) warranty on your
2013-2014 small off-road equipment (outdoor equipment). In California, new outdoor equipment must be designed, built and equipped to
meet the State’s stringent anti-smog standards (in other states, outdoor equipment must be designed, built, and equipped to meet the U.S. EPA
small off-road spark ignition engine regulations). MTD Consumer Group Inc must warrant the ECS on your outdoor equipment for the period of
time listed below, provided there has been no abuse, neglect, or improper maintenance of the outdoor equipment.
Your ECS may include parts such as fuel tanks, fuel lines, fuel caps, valves, canisters, filters, vapor hoses, clamps, connectors, and other
associated emission-related components.
Where a warrantable condition exists, MTD Consumer Group Inc will repair your outdoor equipment at no cost to you including diagnosis,
parts, and labor.
MANUFACTURER’S WARRANTY COVERAGE:
This emission control system is warranted for two years. If any emission-related part on your outdoor equipment is defective, the part will be
repaired or replaced by MTD Consumer Group Inc.
OWNER’S WARRANTY RESPONSIBILITIES:
As the outdoor equipment owner, you are responsible for performance of the required maintenance listed in your owner’s manual. MTD
Consumer Group Inc recommends that you retain all receipts covering maintenance on your outdoor equipment, but MTD Consumer Group Inc
cannot deny warranty solely for the lack of receipts.
As the outdoor equipment owner, you should however be aware that MTD Consumer Group Inc may deny you warranty coverage if your
outdoor equipment or a part has failed due to abuse, neglect, improper maintenance, or unapproved modifications.
You are responsible for presenting your outdoor equipment to MTD Consumer Group Inc’s distribution center or service center as soon as
the 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 the MTD Consumer Group Inc Service Department at 1-800-800-7310 or at
http://support.mtdproducts.com.
GENERAL EMISSIONS WARRANTY COVERAGE:
MTD Consumer Group Inc warrants to the ultimate purchaser and each subsequent purchaser that the outdoor equipment is: (1) designed,
built, and equipped so as to conform with all applicable regulations; and (2) free from defects in materials and workmanship that cause the
failure of a warranted part for a period of two years.
The warranty period begins on the date the outdoor equipment is delivered to an ultimate purchaser or first placed into service.
Subject to certain conditions and exclusions as stated below, the warranty on emission-related parts is as follows:
1.
Any warranted part that is not scheduled for replacement as required maintenance in the written instructions supplied is warranted for
the warranty period stated above. If the part fails during the period of warranty coverage, the part will be repaired or replaced by MTD
Consumer Group Inc according to subsection (4) below. Any such part repaired or replaced under warranty will be warranted for the
remainder of the period.
2.
Any warranted part that is scheduled only for regular inspection in the written instructions supplied is warranted for the warranty period
stated above. Any such part repaired or replaced under warranty will be warranted for the remaining warranty period.
3.
Any warranted part that is scheduled for replacement as required maintenance in the written instructions supplied is warranted for the
period of time before the first scheduled replacement date for that part. If the part fails before the first scheduled replacement, the part
will be repaired or replaced by MTD Consumer Group Inc according to subsection (4) below. Any such part repaired or replaced under
warranty will be warranted for the remainder of the period prior to the first scheduled replacement point for the part.
4.
Repair or replacement of any warranted part under the warranty provisions herein must be performed at a warranty station at no charge
to the owner.
5.
Notwithstanding the provisions herein, warranty services or repairs will be provided at all of our distribution centers that are franchised to
service the subject engines or equipment.
6.
The outdoor equipment owner will not be charged for diagnostic labor that is directly associated with diagnosis of a defective, emissionrelated warranted part, provided that such diagnostic work is performed at a warranty station.
7.
MTD Consumer Group Inc is liable for damages to other engine or equipment components proximately caused by a failure under
warranty of any warranted part.
8.
Throughout the off-road engine and equipment warranty period stated above, MTD Consumer Group Inc will maintain a supply of
warranted parts sufficient to meet the expected demand for such parts.
9.
Any replacement part may be used in the performance of any warranty maintenance or repairs and must be provided without charge to
the owner. Such use will not reduce the warranty obligations of MTD Consumer Group Inc.
10.
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 by the ultimate purchaser will be grounds for disallowing a warranty claim. MTD Consumer Group Inc will not be liable to
warrant failures of warranted parts caused by the use of a non-exempted add-on or modified part.
WARRANTED PARTS:
The repair or replacement of any warranted part otherwise eligible for warranty coverage may be excluded from such warranty coverage
if MTD Consumer Group Inc demonstrates that the outdoor equipment has been abused, neglected, or improperly maintained, and that
such abuse, neglect, or improper maintenance was the direct cause of the need for repair or replacement of the part. That notwithstanding,
any adjustment of a component that has a factory installed, and properly operating, adjustment limiting device is still eligible for warranty
coverage. Further, the coverage under this warranty extends only to parts that were present on the off-road equipment purchased.
The following emission warranty parts are covered (if applicable):
