Brake adjustment - IVT transmissions
To adjust the brakes on IVT transmission:
1. Lift the rear of the tractor and safely support it
with a pair of jack stands.
2. Remove the rear wheels with a 3/4” wrench.
3. Release the parking brake.
4. Remove the cotter pin that retains the ferrule of
the drive control rod. See Figure 3.6.
5. Slide the ferrule of the drive control rod out of the
brake disengagement block.
NOTE: Once the control rod is disengaged, the
springs will clamp the brake shoes against the
drum. This will automatically center the disen-
gagement block.
6. Adjust the ferrule until it slides into the hole in
the disengagement block with out applying pres-
sure to it.
7. Install a new cotter pin into the ferrule to secure
it to the disengagement block.
8. Repeat the steps 4 - 6 on the other side of the
tractor.
9. Install the rear wheels. Tighten the lug nuts to a
torque of 53 - 60 ft lbs. (72 - 81 Nm).
10. Take the tractor off of the jack stands.
11. Test drive the tractor in a safe area before
returning it to service.

Brake puck/rotor replacement - HydroGear Trans-
missions
On HydroGear transmissions, the brake pucks are
a wearing part that will need to be serviced from time to
time. If a tractor is operated with the parking brake
dragging, the pucks will wear out rapidly and the brake
rotor will develop hot spots. If the tractor is operated
long enough, the rotor may have grinding marks on it
with excessively worn pucks.
The brake pucks and the rotors are serviced at the
same time. To service the brake pucks:
1. Jack up the tractor and remove the rear wheels
as described in the previous section.
2. Make sure the brakes are released.
3. Disconnect the brake rod spring. See Figure 3.7.
! CAUTION ! CAUTION
If the rotor shows hot spots or any
other signs of damage, including
warpage, it must be replaced. Fail-
ure to do so can result in the failure of the brakes
