5.5 HYDRAULIC BRAKES (OPTION)
5.5.1 MAINTENANCE PROCEDURES BEFORE EACH SEASON
1. Check that all lines and hoses are undamaged and leak tight.
2. Check braking effect and adjust the brakes.
ADJUSTING THE BRAKES
It is imperative that correct brake adjustment is verified when the machine is new and
subsequently twice a year.
NOTE: Unless the brakes are adjusted, the brake action will wear off over time, and in the end,
the brakes will not work at all.
Hitch the implement to the tractor when making this adjustment. Measure the stroke (I) of the
brake cylinders between unbraked and braked conditions. When performing this
measurement, ensure that the rod (J) is fully retracted when the brakes are off.
If the stroke (I) exceeds 55 mm, the brake must be adjusted.
Remove the fork (G) from the brake lever (H). Then unscrew the fork along the rod (J) until a
stroke of 50 mm is achieved. Refit the fork. The fork must be fitted in the third outermost hole
of the lever.
REPLACING BRAKE COMPONENTS
The brake system’s main cylinder, the brake pads and brake drums are wearing parts. When
replacing a component, the entire component must be replaced.
NOTE: All brake pads must be replaced simultaneously.
