Are All Pto Shafts The Same? Modern 540 RPM PTO shafts are the same size. The 1000 RPM PTO shafts on larger tractors are different. The two speeds most commonly used with tractor PTO shafts is 540 and 1000 rpm and the PTO shafts can come in different sizes and lengths.
How do I choose a PTO shaft? PTO Shaft Selection Tips
Measure the bearing cap diameter. Most u-joints have uniform cap diameters.
Measure the cross-kit width, cap to cap length: the u-joint, end of cap to end of cap. You’ll get the most accurate measurement for finding the right PTO shaft by removing the cross-kit from the yokes.
What are the different series of PTO shafts? There are two types of shafts, domestic and metric, which are identifiable by their shapes. Domestic are generally one of four shapes: round, square, rectangle or splined. Metric are: bell, star or football shaped.
How many types of PTO are there? There are two major types of independent PTO; mechanical and hydraulic. A mechanical-independent PTO uses a separate on-off selector, in addition to the PTO control lever. Often the tractor must be stopped or off to change this selector position.

How short can you cut a PTO shaft?
The manufacturer of the PTO shafts recommends adding 40mm (about an inch and a half) to the amount to cut off the plastic tube and the steel telescoping tube of each half of the PTO. The overlap length is 150mm for this example. Add 40mm to that for our cutoff length. The amount to cut off is 190mm.
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 overlap should a PTO shaft have?
The PTO shaft halves (the actual shaft, not the plastic outer shields) need to overlap somewhere around 4-6″ at max extension.
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 many splines are on a 1000 rpm PTO?
The 1000 rpm PTO stub shaft has either 20 splines or teeth with a 1 3/4 inch diameter or may have 21 splines or teeth with a 1 3/8 inch diameter.

How do I know if I have PTO yoke?
The simplest way to figure out whether a PTO is North American or metric is to determine the shape of the tubing and shafting. A PTO is domestic if the tubing/shafting is square, rectangle, hex or splined. If the tubing/shafting is bell, lemon or star-shaped, then it is metric.
What does a 540 PTO mean?
The 540/540 Economy PTO allows operators to select the engine rpm needed for their power take-off (PTO) application. This selection gives 540 rpm to the PTO shaft and delivers the fully-advertised horsepower at rated engine speed.
What is a slip clutch PTO shaft?
A PTO slip clutch is a torque limiting device that, when overcome with too much torque, limits the amount of torque being transferred from the tractor to the implement. This is accomplished by, you guessed it, slipping or spinning free which allows the two sides of the PTO shaft to spin at different speeds.
