• Fill the fuel tank outdoors in an open area when
the engine is cold. Wipe up any gasoline that
spills.
• Do not fill the fuel tank completely full. Add
gasoline to the fuel tank until the level is 1/4 to
1/2 in. (6 to 13 mm) below the bottom of the
filler neck. This empty space in the tank allows
the gasoline to expand.
• Never smoke when handling gasoline, and stay
away from an open flame or where a spark may
ignite the gasoline fumes.
• Store gasoline in an approved container and
keep it out of the reach of children.
• Never buy more than a 30-day supply of
gasoline.
• Always place gasoline containers on the ground
away from your vehicle before filling.
• Do not fill gasoline containers inside a vehicle or
on a truck or trailer bed because interior
carpets or plastic truck bed liners may insulate
the container and slow the loss of any static
charge.
• When practical, remove gas-powered equipment
from the truck or trailer and refuel the
equipment with its wheels on the ground.
• If this is not possible, refuel such equipment on
a truck or trailer from a portable container, not
from a gasoline dispenser nozzle.
• If you must use a gasoline dispenser, keep the
nozzle in contact with the rim of the fuel tank or
container opening at all times until fueling is
complete.

Operation
Using Stabilizer/Conditioner
Use a fuel stabilizer/conditioner in the tractor to provide the
following benefits:
Note: Determine the left and right sides of the tractor from
the normal operating position.
• It keeps gasoline fresh during storage for up to 90 days.
For longer storage, drain the fuel tank.
Controls
• It cleans the engine while it runs.
Become familiar with the controls (Fig. 2) before you start
the engine and operate the tractor.
• It eliminates gum-like varnish buildup in the fuel
system, which causes hard starting.

Setting the KeyChoice)
Switch to
Operate in Reverse
Using the Safety Interlock
System
The interlock feature on the tractor prevents the power
take-off (PTO) from operating when you back up the
tractor. If you operate the tractor in reverse with the blades
(PTO) engaged (i.e., with the mower blades or other
attachment running), the engine will stop. Do not mow in
reverse unless it is absolutely necessary.
Caution
If the safety interlock switches are disconnected or
damaged, the tractor could operate unexpectedly,
causing personal injury.
If you need to use the blades (PTO) while backing up, turn
off the interlock feature using the KeyChoice switch
located near the seat bracket (Fig. 12).
• Do not tamper with the interlock switches.
• Check the operation of the interlock switches
daily and replace any damaged switches before
operating the tractor.
• Replace switches every 2 years regardless of
whether they are operating properly or not.

Operating Tips
• For the best performance, operate the engine at the
maximum speed. The mower requires air to thoroughly
cut grass clippings, so do not set the height-of-cut too
low or completely surround the mower in uncut grass.
Always leave one side of the mower free from uncut
grass to allow the air to be drawn into the mower.
• Cut the grass slightly longer than normal to ensure that
the cutting height of the mower does not scalp any
uneven ground. When cutting grass longer than 6 in.
(15 cm) tall, cut the lawn twice to ensure an acceptable
appearance.
• It is best to cut only about 1/3 of the grass blade. Do not
cut more than that unless the grass is sparse or it is late
fall when grass grows more slowly.
• Alternate the mowing direction to keep the grass
standing straight. This also helps disperse clippings and
enhances decomposition and fertilization.
• Grass grows at different rates at different times of the
season. To maintain the same cutting height, which is a
good practice, mow more often in early spring. As the
grass growth rate slows in mid summer, mow less
frequently.
• If the grass is longer than normal, or if it contains a high
degree of moisture, raise the cutting height higher than
usual, cut the grass at that setting, and then cut the grass
again at the lower, normal setting.
• If you must stop the tractor while mowing, you may
leave a clump of grass clippings on your lawn. To avoid
this, do the following:
– Engage the blades and move to a previously cut
area.
– Disperse the clippings evenly by raising the mower
1 or 2 height-of-cut settings while driving forward
with the blades engaged.
• Use the washout port to clean clippings and dirt from
the underside of the mower after each use. If grass and
dirt build up inside the mower, the cutting quality will
eventually become unsatisfactory.
• Maintain sharp blades throughout the season. Sharp
blades cut grass cleanly without tearing or shredding the
grass blades. Tearing and shredding the grass turns it
brown at the edges, which slows its growth and
increases the chance of disease. Every 30 days, check
the blades for sharpness and file down any nicks.
