NEUTRALADJUSTMENT:
Swing upper control levers out into the neutral slots.
Raise upper body to the fully open position. Start engine
and disengage parking brake.
Caution should be used when releasing parking brake as mower may tend to creep or
move prior to adjustment.
If adjustment is required, loosen lock nuts at each end of the control rods and back off
the tension on each spring block.
Turn control rods in or out until neutral is obtained on each hydrostat.
Re-tighten lock nuts and tension bolts on spring blocks.
