d) When operating in extremely rough conditions it may be necessary to
position the anti-scalp rollers one or two holes higher than described in
"c" to prevent damage to the rollers and/or bolt failure. See Figure 8.
NOTE: When anti-scalp rollers are placed in these positions, reduced
deck flotation will result.
5.2.2 Pump drive belt tension adjustment:
No adjustment necessary.
5.2.3 Mower deck drive belt:
No adjustment necessary.
5.2.4 Blade drive belt tension:
No adjustment necessary.
5.2.5 Hydro Drive Linkage Adjustment:
a) Adjust Speed Control Linkage and Neutral Safety Switch
1. Stop engine and wait for all moving parts to stop.
2. Move speed control lever (located on console) to the full forward
position and check orientation of tabs on the ends of the speed control
crank. See Figure 9. These tabs should be pointing straight down at
the 6 o'clock position or slightly forward. Adjust threaded yoke at the
bottom of speed control linkage until tabs are positioned correctly. See
Figure 9.
3. Pull speed control lever back to neutral. Check that the neutral safety
switch actuating tab has depressed the plunger of the switch so that
there is about 5/16" between the tab and the switch. See Figure 9. If
necessary, move the switch fore and aft.
NEUTRAL SAFETY SWITCH ADJUSTMENT
b) Adjust Neutral Control Linkages
1. Raise the rear of the machine up onto jack stands high enough to
raise the drive wheels off of the ground.
2. Start the engine and move the throttle ahead to the full throttle position.
Place the neutral lock latches in the forward position as shown in Figure
4 (c) and move the speed control lever to the "mid-speed" position.
Note: The park brake must be disengaged and the OPC levers must
be held down whenever the speed control lever is out of the neutral
position or the engine will kill.
3. Squeeze the respective drive lever until an increased resistance is
felt; this is where neutral should be.
If the wheel turns while holding the drive lever in neutral, the neutral
control linkages need to be adjusted. If wheels stop then go to step 7.
