5.3 PARKING/SERVICE BRAKE__________________________________________________

Inspect brakes:
whenever wheels are pulled,
if tractor creeps on hills with parking brake applied,
there is a noticeable increase in stopping distance.
If brakes 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.
3. Back off jam nut (B).
4. With the brake pedal all the way up (disengaged)
turn in adjusting nut (A) 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.

5.4 BRAKE SWITCH ___________________________________________________________

The brake pedal is equipped with a proximity switch. This
switch closes when the brake is engaged. If the operator
leaves the seat without engaging the brake the switch
remains open and will automatically shut down the
engine. See Section 4.2, Operator Back-up System.
The switch consists of two pieces, a stationary sensor (J)
and a magnet (K) that pivots with the brake pedal. A
faulty or loose switch can prevent the engine from
starting.
For correct operation, adjust air gap (I) between magnet
and sensor to 1.5 - 2 mm.
6. Tighten jam nut to lock adjustment in place.
7. Check that plugs (C) 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. Park tractor on an incline
and engage parking brake. Check that parking brake
engages properly and prevents the tractor from rolling.
