What Is a PTO Shaft?
In tractors, the PTO (Power Take-Off) drive shaft is one of your machine’s most important parts. Tractor PTO shafts transfer power from the engine to the implement towed behind the machine.
PTO drive shafts are complete assemblies that consist of five major components:
How Do PTO Shafts Work?
Many pieces of ag equipment lack independent power, which is where tractor PTO shafts come in.
Power Take-Off shafts have connections at each end that attach to your tractor and machinery. Tractor PTO shafts operate using simple switches and can rotate between 540 and 1,000 RPMs, depending on the equipment. When engaged, the shaft pulls power and torque from the tractor transmission to deliver the right amount of power to your implements, letting you get to work.
PTO shafts vary in size, and you need to find one that matches the coupling on the equipment you want to tow. Connecting your implement to your tractor should be easy. If you have to lift your equipment off the ground to connect the shaft or have a shaft that is too long, forcing the connection could damage both. If you have your existing PTO shaft handy, it’s easy to confirm your length. Close it and measure from PTO yoke to yoke.
