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.
6003-004
Mow up and down, not side to side
_1_ ARNINGt

SAFETY
• 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.
Children
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.
