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.
• Do not mow near drop-offs, ditches, or
embankments. The machine could suddenly roll
over if a wheel is over the edge or if the edge
caves in.
WARNING!
When using the machine, approved personal protective equipment (shown in
illustrations) shall be used. Personal protective equipment cannot eliminate the risk of
injury but it will reduce the degree of injury if an accident does happen. Ask your retailer
for help in choosing the right equipment.

Motion 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.
