The park brake is applied when brake lever (A) is

Adjust park brake after the first 10 hours of

operation and every 100 hours thereafter.

To increase brake force:

1. Move lever (A) down to release brake.

2. Turn knob (B) clockwise (towards the seat) until

brake force is adequate. Force required to raise

lever to the engaged position should be 70 to

90 lbs. (300 - 400 N).

knob (B) will reach the end of the adjustment

range. At this time, perform the following

adjustment:

1. Turn knob (B) counter-clockwise (towards the

side console), back to the beginning of the

adjustment range.

2. At the rear of both tractor frame legs, remove

locknut (C) and retaining bar (D). Move link (E)

to welded bolt (F) and replace retaining bar and

locknut.

3. Turn locknut (C) until the gap between the head

of the welded bolt (F) and retaining bar (D) is

3/8 inch (10 mm) as shown.

4. Turn knob (B) on brake lever clockwise until

brake force is adequate. Force required to raise

lever to the engaged position should be 70 to

90 lbs. (300 - 400 N).
