Craftsman riding mowers are also called lawn tractors and include adjustable brakes. Brakes need adjusting if stopping distance is poor, and Craftsman recommends that you adjust the brakes if the riding mower needs more than 6 feet of stopping distance at high speed in the highest gear. The adjustable system is found on the side of the transaxle. Adjusting the brakes on the Craftsman riding mower includes making a measurement and adjusting a nut.
Press down on the clutch pedal and set the parking brake.
Identify the brake adjustment feature, located below the brake operating arm. It includes a jam nut, regular nut and rod. Measure the distance between the brake operating arm and the regular nut. The regular nut is distinct from the jam nut -- the jam nut is the outer nut.
Loosen the jam nut and turn the regular nut so that it's exactly 1-1/2 inches between the arm and regular nut. Double-check that the parking brake is engaged, then re-tighten the jam nut so it abuts the regular nut and holds it in place at the correct distance. Try the riding mower stopping procedure again in a safe place.
