Secure the tractor against movement!
1. Lift the tractor rear wheels.
2. Loosen the nuts (2), nuts (6) and nuts (8).
3. Loosen the screw (7).
4. Let your helper turn one wheel and simultaneously tighten the screw (5) until the wheel starts to be
braked.
5. Loosen the screw (7) by 5/6 turn, check, if the wheel can turn freely and secure the screw (7) with the nut
(6).
6. Adjusting process is the same at the right-hand and left-hand sides.
If asymmetry of brake effect appears between the left and right brakes, it is necessary to loosen the adjusting
screw (7) of the brake with bigger brake effect, until the brake effects of the right and left wheels are equal.
But the screw can be loosened maximum by 1/2 turn. If asymmetry of brake effect is not eliminated even
after such adjusting, the tractor brakes must be adjusted in an authorized service.
