Spindle Brake Inspection and Replacement
Blade and pulley brake inspections should be
performed every 50 blade on and off cycles.
Before beginning service, park THE BEAST on a flat
and level surface, with the ignition switch off, the key
removed, and the blades disengaged. Also, disconnect
the spark plug wires from the spark plugs and ground
them against the engine to prevent inadvertent starting.
1. Engage the blade handle (make certain the engine
cannot start) to pull the brakes off of the pulleys.
2. Remove the pulley guard from the main deck.
Note: The wings will need to be in the operational
mode in order to remove the guard and observe the
brakes.
3. Visually inspect the brake pads for wear. Make
certain that no metal has been touching the
pulleys.
4. The brake pad material should be approximately
1/8-inch thick. Replace the brakes if the material is
less than 1/16-inch thick. Note: Replacing both
brakes is recommended if replacement of one
brake is required.
5. To replace the brake, use a pair of pliers to remove
the springs.
6. Remove the two mounting bolts and disconnect the
spring from the cable.
IMPORTANT! The mower belts are adjusted to
ensure the blades stop turning within seven (7)
seconds of releasing the blade control lever. If you
are making any belt adjustments whatsoever, for
your safety and the safety of others around you, you
must ensure the belts are re-adjusted to achieve this
design specification.
When wing mowers are in use, blades may not stop
in 7 seconds. Visual warning disks on both of the
wing mowers indicate whether the blades are
turning. Do not approach the mower or attempt any
service until after the visual warning disks have
completely stopped turning.
Operating Instructions
7. Discard all of these parts. DO NOT reuse springs.
New brakes are equipped with new springs for
proper braking.
8. Install the new brakes by reversing the procedure
in steps 5 and 6.
9. Disengage the blade handle and inspect the brake
contact surface. All of the brake pad contacting
material should be contacting the bottom of the
pulley.
Note: Springs may vary from those pictured based on
the particular application.
