How do you adjust the PTO clutch on a John Deere 4020?
To adjust, there is a bolt in the side of the clutch pedal that takes a 3/4″ wrench to loosen. Loosen the bolt about 1 turn. Then slide the bolt rearward in the slot until you get the 1 inch of free travel in the pedal.
Are PTO shafts universal?
The parts of a PTO shaft consist of the internal and external PTO yoke, universal joint, safety chain and safety shield. Several different types of PTO shafts are available, so it’s essential to choose the right one for your equipment and applications.
How much should a PTO shaft overlap?
In the collapsed position the driveline should be approximately 2″ from bottoming out to prevent possible damage to the tractor or implement. When the PTO is in the maximum extended position, the ideal minimum overlap of the two halves should be approximately 6″ (see figure on right).
How do you troubleshoot a PTO clutch?
How to Test a PTO Clutch
- Lift the utility vehicle up with a floor jack.

Should you grease PTO splines?
The PTO shaft should be greased regularly to keep the universal joints from failing and to stop the shaft from seizing. Failure to grease your shaft regularly or as outlined in the PTO shaft’s maintenance schedule could result in end thrust potentially destroying the implement’s gearbox.
How does a PTO tractor work?
The tractor’s stub shaft, often called the PTO, transfers power from the tractor to the PTO -driven machine or implement. Power transfer is accomplished by connecting a drive shaft from the machinery to the tractor’s PTO stub shaft. The PTO and drive shaft rotate at 540 rpm (9 times/sec.) or 1,000 rpm (16.6 times/sec.)
