Adjust brakes after replacing or servicing brake assembly, or if pedal
travel becomes excessive.

at mowing speed while applying a slight pressure on brake pedal
for about 5 seconds. Release and repeat five times before
making the final adjustment.
2. Fully loosen adjusting nut (C).
3. By hand, pull cable behind adjusting nut (B) away from pedal
until brake pads just contact brake disk. Thread adjusting nut
(B) up until it contacts the mounting plate. Tighten nut (C) up to
lock adjustment in place. Torque nut (C) to 20 ft. lb. (27 Nm).
Do not over torque or turn cable.
4. Repeat for second cable.
5. Start mower and check operation of brakes. Park mower on an
incline (approx. 16.7° slope) and engage parking brake. Brake
