PTO Shaft Guide | PTO Shaft Information | How To Measure A PTO Shaft | Choosing The Correct PTO For Your Implement

A Power Take-Off (PTO) shaft connects an agricultural implement (such as a power harrow, mower or diet feeder) to a suitable power source (such as a tractor). The shaft is defined simply by its universal joint dimensions, its length, and its connection types.

Simple PTO Identification Guide

Identifying the correct size of your PTO drive shaft is critical. It means you get the correct parts when repairing or replacing your broken or damaged PTO shaft. This saves you time and means your machine is up and running quicker.

Using these 2 simple steps will help you to identify the type/series and size of shaft you need.

1. Measure the UJ Dimensions:

• A, The cup size = AØ
• B, The overall length = A (with bearing caps on)

2. Measure the PTO Length:

If a new complete PTO shaft is required; measure the distance from centre to centre of the UJ’s when the shaft is closed.
