Blade Brake Band Adjustment
NOTE: The length of the actuator rod is adjusted
by disconnecting the bottom clevis and shortening
or lengthening accordingly. The standard pre-set
length of the actuator rod is set at the factory at
8-1/4 in. (209 mm).
d. Check the brake drum on the pulley. If
excessive wear is present, it will be necessary
to replace worn parts.
Transmission Control
IMPORTANT: The proper adjustment of the transmission
control stops is essential for efficient operation
and life of the transmission. These stops are
properly adjusted at the factory and should only require
readjustment if the transmission or related
control linkage is removed or changed.
NOTE: It would not be unusual for a new machine,
after initial 5 or 10 hours of operation, to begin to not
travel straight (this is due to the break-in of the
transmissions). In this case, proceed to Straight
Ground Travel Adjustment - Step 4.

Set Forward Travel Limit (Stop) - Step 1
1. Move the Forward Speed Control (FSC) lever to
the most FORWARD position.
2. Check clearance of the RH and LH steering lever
actuator arms with the frame and adjust forward
stop bolt so each lever clears the frame
by at least 1/16 in. (1.6 mm). Clearance of the
arm to the frame should be checked while applying
pressure back on the arm to remove
any slack in the linkage.
