Brake puck/rotor replacement
On Hydro-Gear transmissions, the brake pucks are wearing parts that will need to be serviced from time to time.
If a mower is operated with the parking brake dragging, the pucks will wear out rapidly and the brake rotor will
develop hot spots. If the mower is operated long enough, the rotor may have grinding marks on it with excessively
worn pucks.
NOTE: Dragging brakes can cause symptoms similar to a failing transmission. Dragging brakes will also
accelerate wear on the transmission.
The brake pucks and the rotors are serviced at the same time. To service the brake pucks:
1. Lift and safely support the rear of the mower.
2. Make sure the parking brake is released.
3. Disconnect the secondary brake rod from the brake
shaft bell crank by removing the bowtie clip.
See Figure 4.5.
4. Slide the brake rod, spring and washer out of the
brake cam arm.
5. Loosen the rear mounting bolt. See Figure 4.6.
! CAUTION ! CAUTION
If the rotor shows hot spots or any other signs of damage, including warpage, it must be
replaced. Failure to do so can result in the failure of the brakes
