Tractor Clutch Disc is a key component of the clutch system of a tractor. It is a flat, round disc made of friction material, such as ceramic or organic material, sandwiched between metal plates. This clutch disc is located between the engine flywheel and the pressure plate. When the clutch pedal is engaged, the pressure on the clutch disc is released by the pressure plate, that allows it to spin freely with the engine. When the clutch pedal is disengaged, the pressure plate applies pressure on the Tractor Clutch Disc, engaging it with the flywheel and transmitting power from the engine to the transmission.
