Slope Operation
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 (10 degrees maximum),
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 that you will not
have to stop while on the slope.
• Do not mow on wet grass. Tires may lose traction.
• Avoid starting, stopping, or turning on a slope. If
the tires lose traction, disengage the blades and
proceed slowly straight down the slope.
• Keep movement on the slopes slow and gradual.
Do not make sudden changes in speed or
direction, which could cause machine to roll over.
• Use extra care while operating machine with grass
catchers or other attachments; they can affect the
stability of the machine.
• Do not use on steep slopes.
• Do not try to stabilize the machine by putting a foot
on the ground.

CONTROLS
Steering Control Levers
The machine's speed and direction are continuously
variable using the two steering controls. The steering
controls can be moved forward or backward about
a neutral position. Furthermore, there is a neutral
position, which is locked if the steering controls are
moved outward.
When both controls are in the neutral position (N), the
machine stands still.
By moving both controls an equal amount forward
or backward, the machine moves in a straight line
forward or backward respectively.
In order, for example, to turn right while moving
forward, move the right control towards the neutral
position. The rotation of the right wheel is reduced and
the machine turns to the right.
Zero turn can be achieved by moving one control
backward (behind the neutral position) and carefully
moving the other steering control forward from its
neutral position. The rotation direction when zero
turning is determined by which steering control is
moved backward behind the neutral position. If the left
steering control is pulled backward, the machine turns
to the left. Use extra care when using this maneuver.
If the steering controls are in uneven positions when
standing still or do not fit in the slots for moving the
controls outward, they can be adjusted.

Fuel tank
IMPORTANT INFORMATION
Experience indicates that alcohol blended
fuels (called gasohol, ethanol or methanol) can
attract moisture which leads to separation and
formation of acids during storage. Acidic gas
can damage the fuel system of an engine while
in storage. To avoid engine problems, the fuel
system should be emptied before storage of
30 days or longer. Drain the gas tank, start the
engine and let it run until the fuel lines and
carburetor are empty. Use fresh fuel the next
season. See Storage Instructions for additional
information. Never use engine or carburetor
cleaners in the fuel tank or permanent damage
may occur.
When operating in temperatures below 32° F.(0° C.),
use fresh, clean winter grade gasoline to insure good
cold weather starting.
