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.

What is the purpose of slip clutch?
The slipper clutch is designed to partially disengage or ‘slip’ when the rear wheel tries to drive the engine faster than it would under deceleration. In very simple terms, a slipper clutch disengages or ‘slips’ until the engine and wheel speeds are compatible.
How long of a PTO shaft do I need?
To determine the length you need your PTO shaft to be, you need to measure the distance between the groove on your tractors PTO output shaft and the implements PTO output shaft.
Are all PTO shafts the same?
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 many splines does a 540 PTO shaft have?
6 splines
In case of 540 rpm, the shaft has 6 splines, while for the 1000 rpm shaft, the number of splines is 21.
What rpm is 540 PTO?
When operated at full recommended speed, a PTO shaft will rotate clockwise at 540 revolutions per minute (rpm), which equals 9 revolutions per second, or at 1,000 rpm (16.7 revolutions per second). As shown in the Table 1, a 540 rpm shaft travels 7.1 feet per second, while a 1,000 rpm shaft turns 13.1 feet per second.
What grade should shear bolt for bush hog?
Grade 2 shear
A 1/2 x 3” Grade 2 shear bolt protects the gearbox and drive- line from damage. The 35 HP gearbox is designed for 540 RPM input speed giving the blades a 12,468 ft./min.
Why is PTO speed 540?
540 was the early standard primarily because it was the speed of the intermediate shaft in the Ford 9N, 2N, and 8N transmission at the engine speed for near maximum engine power. That PTO was very simple inside the tractor, just an extension of the transmission intermediate shaft.
What does it mean 540 PTO?
power take-off
The 540/540 Economy PTO allows operators to select the engine rpm needed for their power take-off (PTO) application. The economy position provides 540 rpm to the PTO at 1700 engine rpm.
Are all tractor PTO shafts the same?
How much overlap should a PTO shaft have?
First, there should be at least a one-third overlap between the shaft and the tube. If you’re using a slip sleeve, the overlap should be approximately 3 inches. If the shaft is too long, it will bottom out and create a conflict between the tractor and the shaft.
How many splines are on a 540 rpm PTO?
6-spline
540 (6-spline)/540 (6-spline) economy rpm/1000-rpm (21-spline) rpm PTO, 45-mm (1-3/4-in.)
What is the best PTO shaft?

What spline is a 540 PTO?
540 economy rpm (6-spline)/1000 (21-spline)/1000 (21 spline) economy rpm PTO, 45-mm (1-3/4-in.)
What does a 540 PTO mean?
How tight should a slip clutch be?
The maximum tight setting for the slipper is just at the point where there is little or no tire slippage on a high traction surface such as carpet or a prepared racetrack. The slipper should not be tightened to the point that clutch slippage is completely eliminated.
