TorQmaster AUTOMATIC CLUTCH
The automatic clutch offers a level of implement overload protection not possible with other types of clutches. The compact, efficient design disconnects the power source from the drivetrain when overload occurs, and does not reconnect until the speed is reduced to near zero. During disengagement, the patented design does not allow or generate damaging torque spikes or heat.

TorQmaster FRICTION CLUTCH
The friction clutch is indispensable in certain agricultural implement applications. The friction clutch is the only torque limiter to continuously transmit power while overloaded. This is valuable during start up of high inertia machines, as well as for leveling out torsional fluctuations due to high cyclic loads. During operation the clutch transmits limited power. The patented design isolates and dissipates heat quickly to protect the machine.

RATCHET CLUTCH
The ratchet clutch allows implement overload protection with a unique pulsating torque while disengaged. The compact clutch slips in a pulsating manner when overload occurs, which aids in pushing the blockage through. Therefore, the operator may not need to leave the operator seat or even slow down to clear the blockage.

SHEAR BOLT YOKE
The shear yoke offers simple, economical implement overload protection. Besides the traditional implement mounted configuration, the free motion and hidden bolt tractor shaft mounted* options make hook-up and service more user friendly. The compact, efficient design disconnects the power source from the drivetrain when overload occurs. During disengagement, the design does not allow or generate damaging torque spikes or heat. After the operator replaces the easily accessible bolt, the machine can be restarted.

OVERRUNNING CLUTCH
Any implement with a large rotating moment of inertia may need protection by allowing it to free wheel to a stop independent of when the PTO is stopped. Overrunning clutches will not absorb any energy so inertia start-up peaks must be dampened by other means.
