Operation
tipping backward. Having a full width ramp provides
a surface for the frame members to contact if the
unit starts to tip backward. If it is not possible to use
one full width ramp, use enough individual ramps to
simulate a full width continuous ramp.
Ramp should be long enough so that the angles
between the ramp and the ground and the ramp and
the trailer or truck Do Not exceed 15°. A steeper
angle may cause mower deck components to get
caught as the unit moves from ramp to trailer or
truck. Steeper angles may also cause the unit to tip
backward. If loading on or near a slope, position
the trailer or truck so it is on the down side of the
slope and the ramp extends up the slope. This will
minimize the ramp angle. The trailer or truck should
be as level as possible.
Important: Do Not attempt to turn the unit
while on the ramp, you may lose control and
drive off the side.
Avoid sudden acceleration when driving up a ramp
and sudden deceleration when backing down a ramp.
Both maneuvers can cause the unit to tip backward.
