A ratchet torque limiter is a part of the PTO tractor drive shaft that interrupts power transmission in the event of a torque spike or overload exceeding the setting. After removing the cause of the overload, the torque limiter will automatically reengage. Ratchet torque limiters are typically used to protect appliances subjected to constant or alternating torque from overloads.
