PTO shafts with overrunning clutch for smooth power transfer without kickback

Do you work with a mower, tedder or another implement with high rotating mass? Then a PTO shaft with overrunning clutch is a smart choice. This type of shaft prevents the rotational energy of the implement from pushing back into your machine when the PTO is disengaged. It is especially useful for older machines or models without a built-in overrunning clutch.

At Techniek Totaal, we offer various PTO shafts with overrunning clutch, suitable for both tractors and compact tractors. We supply models from brands like Walterscheid, Bondioli & Pavesi, Weasler and Rotaro. By choosing the right type, you extend the life of your driveline and work more smoothly, with less risk of damage.

What is an overrunning clutch and how does it work?

An overrunning clutch is a mechanism that prevents torque from returning to the driveline after the PTO is disengaged. It works like a one-way bearing: it allows power from the tractor to the implement, but blocks motion in the opposite direction.

This prevents sudden shocks in the transmission and protects parts like the gearbox and engine. You’ll especially notice the difference when using equipment like a drum mower, rotor or tedder. Without a clutch, the implement can keep spinning and push back against the machine. With an overrunning clutch, you simply turn off the PTO and the implement winds down safely.

Tips for using a PTO shaft with overrunning clutch

Make sure to choose the correct length and profile for your machine. Also check the required horsepower at 540 or 1000 RPM. Always mount the shaft on a clean, greased connection and ensure the clutch turns freely.

Maintenance is key. Regularly grease the cross joints and sliding tubes, and check the clutch for wear. A seized or damaged clutch can lose its function and cause damage.

Benefits of a PTO shaft with overrunning clutch

A PTO shaft with overrunning clutch offers several benefits:

• Prevents damage to gearbox or driveline

• Ideal for mowers, tedders and implements with rotating mass

• Comfortable disengagement without kickback

• Suitable for older tractors without built-in clutch

For anyone who values smooth operation and machine protection, this type of PTO shaft is an excellent investment.
