ABSTRACT:
In an adjustable friction overload clutch for protecting the drive line between a power take-off shaft on a tractor and an agricultural implement, one or more Belleville spring washers bias plates and friction discs together. Adjustable bolts extend through the Belleville spring washer and are attached to the plate adjacent to the washer. Springs are held by the bolts and extend between the Belleville spring washer and a nut on the bolt. By adjusting the bolts, a variable torque can be set which is less than the maximum torque exerted by the Belleville spring washer when it is initially assembled on the clutch.
