Changing to Machine Operation
Rotate each by-pass valve clockwise 1 turn and hand
tighten them (torque of approximately 71 in-lb (8
N⋅m)) (Figure 36).
Note: Do not over tighten the by-pass valves.
The machine will not drive unless by-pass valves are
turned in.
Loading Machines
Use extreme caution when loading units on trailers or
trucks. One full width ramp that is wide enough to
extend beyond the rear tires is recommended instead of
individual ramps for each side of the unit (Figure 37).
The lower rear section of the tractor frame extends back
between the rear wheels and serves as a stop for 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.
The ramp should be long enough so that the angles
do not exceed 15 degrees (Figure 37). A steeper angle
may cause mower 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.
WARNING
Loading a unit onto a trailer or truck increases the
possibility of backward tip-over and could cause
serious injury or death.
• Use extreme caution when operating a unit on
a ramp.
• Use only a single, full width ramp; Do not use
individual ramps for each side of the unit.
• If individual ramps must be used, use enough
ramps to create an unbroken ramp surface
wider than the unit.
• Do not exceed a 15 degree angle between ramp
and ground or between ramp and trailer or
truck.
• Avoid sudden acceleration while driving unit up
a ramp to avoid tipping backward.
• Avoid sudden deceleration while backing unit
down a ramp to avoid tipping backward.
