6.5 TOWING A DISABLED MACHINE
Towing a disabled machine should only be attempted as
a last resort, after exhausting all other options. Make
every effort to repair the machine, and move it under its
own power.
Towing is only possible by using the "towing" feature built
into the hydrostatic pump and disengaging the park brake
on the front axle.
1. Securely block all four wheels.
2. Locate the six brake release bolts (1) at the base of
the front axle. Mark a line on the socket so you can
accurately count the number of turns each bolt
makes as you perform the procedure.
3. Alternately screw the release bolts clockwise in 1/2
turn increments. Turn until resistance is felt.
4. Turn the tow option engagement screw (2) on the
hydrostatic transmission counterclockwise three
turns.
5. Carefully remove the blocking from each tire and tow
the machine to a secure location.
Note: This procedure does not alter any relief settings.
After the machine has been towed to a secure location,
reactivate the parking brake.
1. Block all four wheels.
2. Turn the tow option screw (2) on the hydrostatic
transmission clockwise three turns.
3. Using a torque wrench, alternately unscrew the
brake release bolts (1) outward in 1/2 turn
increments until the torque drops off sharply.
4. Again, alternately unscrew the bolts outward until
you feel the bolts flange begin to contact against the
special screw.
5. Screw the bolts inward (clockwise) 1/4 turn.
6. The parking brake should now be reactivated and
the front wheels locked.
7. Remove the blocks from the four tires.
8. Verify that the parking brake works.
Note: If the parking brake does not work, check all
activation operations step by step.
