6.7 PARKING/SERVICE BRAKE _________________________________________________

Inspect brakes linings:
whenever wheels are pulled,
if tractor creeps on hills with parking brake applied,
there is a noticeable increase in stopping distance.
The brakes used on this tractor are self-adjusting. To
adjust, apply brakes while operating in reverse. If brakes
linings look good but brakes cannot be self-adjusted, it
may be necessary to adjust brake cable. If linings or
brake drums appear worn, they should be replaced by an
experienced service technician.
To adjust brake cable:
1. Raise tractor and support axle using jack stands or
blocks so that back wheels are slightly raised off the
ground. Block front wheel to make sure unit can't roll.
2. Raise hood and remove battery tray to access brake
pull assembly (A).
3. Back off jam nut (B).
4. With the brake pedal all the way up (disengaged)
turn in adjusting nut (C) and spin wheels slowly by
hand until you feel brakes engage and wheels begin
to bind.
5. Back off adjuster nut slightly until wheels again turn
freely.
6. Tighten jam nut to lock adjustment in place.
7. Check that plugs (D) are in place in slotted holes on
equalizer bracket.
Before returning unit to operation, drive tractor in a flat,
open area and check operation of brakes to make sure
they are operating correctly. Check parking brake to
make sure it engages properly and prevents the tractor
from rolling downhill.
