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 35).
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 36). 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 36). 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.
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.
