817-8420TORQMASTER FREE MOTION CLUTCH YOKE
AB4,AW21 Series Torqmaster Free Motion Clutch Clamp Yoke
AB4,AW21 series torqmaster free motion clutch yoke with 1 3/4-20 spline bore and clamp connection
The Friction clutch is indispensable in certain agricultural implement applications. The friction clutch is the only torque limiter that has the ability to continuously transmit power (at a reduced level) while overloaded. This is valuable during startup of high inertia machines, as well as for leveling out torsional fluctuations due to high cyclic loads. The TorQmaster’s patented technology dissipates heat quickly, improving durability while protecting the machine. The TorQmaster clutch packs are preset for various power levels to meet the needs of the application while reducing torque overloads on the implement, n adjustment is required after slipping. TorQmaster clutch packs are provided with ID tangs that mate with either a free-motion or overrunning clutch yoke. The free-motion design allows for easy connection of the PTO Drive Shaft to the tractor PTO, the overrunning design adds to this also the ability for any implement to free-wheel to a stop. The TorQmaster Friction Clutch must be used in conjunction with a mating TorQmaster clutch yoke and is easily mounted with standard tools.

Clutch packs bolt to yoke and hub for easy service.
Hub offered with or without free motion (patented) or overrunning options.
Yoke options include most North American and European series.
Slip surfaces are controlled to be against iron for efficient heat dissipation and reliable friction coefficient (patented).
Fins are incorporated to quickly dissipate heat and isolate it from other components.
Wear-compensating spring design allows the clutch friction discs to wear uniformly for extended life and maintain torque level.
Torque protection level is determined by spring selection and verified for each assembly.
Auto-lok attachment available (patented).
