11. 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 o if you feel
uneasy on it, do not till on it.
This cutting machine is ;apahle of amputating hands and feet and throwing objects. Failure to observe
the following safety instructions could result in serious injury or death.
Till up and down slopes, not across.
Remove obstacles such as rocks, limbs, etc.
Watch for holes, ruts, bumps and objects hidden under the soil
(e.g. rocks). Uneven terrain could overturn the machine.
Use slow speed. Choose a low enough gear so that you will not
have to stop or shift while on the slope. Always keep tractor in gear
when going down slopes to take advantage of engine braking
action.
Keep all movement on the slopes slow and gradual. Do not make
sudden changes in speed or direction. Rapid engagement or brak
ing could cause the front of the machine to lift.
Avoid starting or stopping on a slope. If tires lose traction, disen
gage tiller and proceed slowly straight down the slope.
For your safety, use the slope gauge included as part of this manual
to measure slopes before operating this unit on a sloped or hilly
area. If the slope is greater than 15° as shown on the slope gauge,
do not operate this unit on that area or serious injury could result.
Do not turn on slopes unless necessary; then, turn slowly and
gradually downhill, if possible.
Do not operate unit near drop-offs, ditches or embankments. A
wheel over the edge or an edge caving in could cause sudden over
turn.
Do not operate tractor on wet grass. Reduced traction could cause
sliding.
Do not try to stabilize the machine by putting your foot on the
ground.
III. CHILDREN

ence of children. Children are often attracted to the machine and
the tilling activity. Never assume that children will remain where
you last saw them.
