sansone, do yourself a favor and buy an operator's manual. All of the necessary adjustment information is in it. Although I can type the instructions from my manual, it will be helpful to you to have the illustrations .
Service Specifications
Brake Pedal Check and Adjustment Interval....Every 200 hours or yearly
Free Pedal Movement Specification...............................25 mm (1 inch)
Brake pedal free play is very important and must be checked at the recommended intervals. If there is no free movement, the brake shoes will wear quickly.
If there is too much free movement, accidents may occur. If there is not the same free movement between LH pedal and RH pedal, it may cause serious accidents.
Put the tractor on level ground, move the range lever in the L position. Stop the engine.
Loosen lock nut and rotate the brake rod to make a free play of 20 to 30 mm (0.79 to 1.18 in.) at the brake pedal. With this much play obtained, tighten the lock nut.
Confirm that the right and left brakes operate simultaneously by running the tractor. If not, adjust both of them by means of the brake rods.
