MODEL ZTR 5421 DRIVE SYSTEM ADJUSTMENTS
FORWARD TRAVEL SPEED ADJUSTMENTS:
Stop engine, move levers to drive position, lightly push each upper control lever forward
until a resistance is felt on the lever.
At this time, check that the forward lever stops on the bottom of each lever are hitting the
stop blocks.
If adjustment is required, loosen the lock nuts on the lever stop and turn the bolt in until the
lever hits the stop block before resistance is felt in the hydrostat.
