What is a power take-off shaft on a tractor?

The Power Take-Off (PTO) shaft is an efficient means of transferring mechanical power between farm tractors and implements. This power transfer system helped to revolutionize North American agriculture during the 1930’s. It is also one of the oldest and most persistent hazards associated with farm machinery.

How many types of PTO are in a tractor?

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.

What are the dangers relating to a power take-off shaft?

What danger can arise from the power take-off shaft of a tractor?

  • If it is not covered, clothing can get caught in it.
  • If it is not disengaged, the steering will lock.
  • If it is not disengaged, the battery will run flat.
  • If it is not covered, the tractor will speed up rapidly.

What is power take-off used for?

Power take-off (PTO) is a device that transfers an engine’s mechanical power to another piece of equipment. A PTO allows the hosting energy source to transmit power to additional equipment that does not have its own engine or motor. For example, a PTO helps to run a jackhammer using a tractor engine.

Are there different size PTO shafts?

Size Importance The series size should correspond with the amount of horsepower your tractor has. There are two different speeds used most commonly with tractor PTO shafts, the 540 (type 1) and 1000 (type 3) RPM.

What size is a tractor PTO shaft?

New PTO shaft length = 1000mm from end to end. So to get our measurement we need to do the following: PTO shaft length – Distance between tractor & implement + 75mm buffer. 1000mm – 800mm + 75mm = 275mm that needs to be removed from the PTO shaft.

What does 540 PTO mean on a tractor?

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.

What’s the difference between 540 and 1000 PTO?

Horsepower is a factor of torque multiplied by speed. With X amount of torque on the shaft, if it is turning 1000 rpm it is transmitting nearly double the horsepower of 540 rpm.
