B. Loosen the adjusting nut securing the pump
and pump mount to the slotted pump support
(Figure 33).
C. Loosen the 3 capscrews securing the pulley guard
bracket to the control panel and pump support.
D. Use a pry bar to pull the pump toward the outside
of the machine until the proper belt tension is
attained; then tighten the adjusting nut securing
the pump and pump mount to the pump support
(Figure 33).
E. Tighten the pivot nut securing the pump mount
to the pump support (Figure 33).
F. Tighten the 3 capscrews securing the pulley guard
bracket to the control panel and pump support.

Adjusting the Transmission
for Neutral
If the machine moves when the lever is released, an
adjustment to the transmission neutral is required.
1. Park the machine on a level surface, stop the engine,
and open the hood.
2. Lift the drive wheel off of the ground using a jack.
Block the front and rear of the wheels.
3. Start the engine and release the parking brake.
4. Slightly loosen the locknut on the top of the neutral
adjustment cam (Figure 34) and rotate the cam hex
until the traction wheel stops rotating. Tighten the
locknut.

5. Move the traction bail completely up and down.
Release the handle and check for wheel rotation. If
the wheel continues rotating, repeat step 4.
6. If the problem continues, stop the engine, check
the linkage for binding or damage, then do the
adjustment procedure again.
7. Set the hole spacing control in the lowest setting (to
the left) and move the transport/aerate switch to the
aerate position (transport tires retracted). Loosen
the 2 screws and adjust the switch tab (Figure 34)
so that the switches are actuated when the pump
control is in neutral and not actuated when the pump
is stroked.
8. Move the ignition switch to the ON position, but do
not start the engine. Move the traction bail in both
directions; the red traction light should come on.
Repeat step 7 if the light does not come on when the
bail is moved in both directions. The second limit
switch must simultaneously activate when the red
traction light is OFF. This switch enables the engine
start circuit.
