BALL SHEAR CLUTCH YOKE

12 Series Ball Shear Clutch Spring-lok Yoke

12 series ball shear clutch yoke with 1 3/8-21 spline bore and spring-lok connection

The ball shear yoke clutch offers implement overload protection. In addition to 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 and helps prevent the generatation of damaging torque spikes or heat. Once the operator replaces the bolt, the machine can be restarted.
