PTO Overload Protection Clutch Introduction

When agricultural machinery manufacturers fit a PTO overload clutch to their implements and equipment, they take into account the maximum torque that the PTO driveline can handle on that piece of equipment including gearboxes, shafts, chains and sprockets.
For example ( maximum gearbox torque rating 2000Nm )
The manufacturer will then fit a PTO overload clutch to the implement with a slightly lower torque rating, thereby ensuring that the maximum gearbox torque rating is not exceeded in the event of a machine blockage or obstruction.
There are generally two types of PTO overload clutch, a cam cut-out clutch and a friction disc torque limiting clutch, commonly all referred to as "PTO Slip Clutches".

PTO Overload Clutch Importance

The important role that the PTO slip clutch plays is often overlooked in the event of a PTO driveline breakdown. These often expensive breakdowns are usually regarded as an unfortunate occurrence or "bad luck".
The reality is that if the PTO slip clutch is properly maintained, it will protect all components in the PTO driveline including the tractor transmission and the implement gearboxes in the event of a machine blockage or obstruction.

PTO Overload Clutch Service Intervals
Friction Clutches can seize or go over their recommended torque limit when not in use and should be serviced once every year, 1 -2 months before the start of the working season.
Cam Cut Out Clutches can seize or go over their torque limit, when the special anti-friction grease which lubricates them breaks down and loses its properties. Cam clutches should be tested once every year and serviced once every two years.
