4020 powershift pto problem

ttyrrell · Oct 24, 2010

I was wondering if anyone could tell me how to adjust the pto on a 4020. It doesn"t like to stop turning with lever disengaged.

Common problem and I don't think there is a easy fix. We owned two with that problem and in order to hook up pto we had to shut off the tractor.
It doesn't take much to stop that shaft from turning but yes it would free wheel.

Early or late 4020? Syncro range or power shift? Gradual or abrupt failure of pto brake?

It could be dirt accumulated under the operating lever under the dash, the lever could be loose where it bolts to the valve body also under the dash.
More than likely the pto brake is worn out,which requires the tractor to be split. The brake is meant to hold the pto shaft only still. If the lever is pulled all the way down to brake with a rotating pto load(rotary mower,baler etc) it will wear the brake out in no time. Also warped pto clutches will override and wear out the brake.

IIRC there are 2 ports on clutch housing to check pto clutch and brake psi. Pressure should be 150-160 ps. i It's common for the brake pad to wear out over time which requires a split to replace pad.
