Pto shafts from Benzi
We offer pto shafts from the renowned Benzi, including standard shafts, wide angle shafts and models with ratcheting clutches, friction disc clutches, shear bolt clutches or freewheel clutches. The assortment also includes forks, universal joints, couplings and guards.
Adapters, splined shafts and shaft components
To customise your power transmission system, we offer adaptors and splined shafts that enable flexible coupling between different profiles and drivetrains. The assortment also includes universal components and accessories that simplify the adaptation and service of your driveline.
Power transmission shaft spare parts
In addition to complete shafts, there is a wide range of
shaft components, spare parts and replacement parts for power transmission, such as drive shafts, universal joints and couplings. This makes it easy to refurbish or replace parts to restore the functionality and safety of your system.
Frequently asked questions about power transmission (FAQ)
What is a pto shaft?
A pto shaft transfers power from the tractor’s power take-off to an implement, such as a mower-crusher, fertiliser spreader or pump.
How do I know which pto shaft I need?
You need to know the power required by the implement, the spline dimensions of the tractor and the implement, and the required length of the shaft. Not sure? Contact us and we’ll help you choose the right one.
What are the most common spline dimensions?
1 3/8" with 6 splines (540 rpm), as well as 1 3/8" with 21 splines and 1 3/4" with 20 splines (1000 rpm). Always check the specifications of your tractor and implement before ordering.
How do I measure the correct length?
Measure between the shaft journals in both the shortest and longest working positions. In the shortest position, the section tubes must not bottom out, and in the longest position, they must overlap sufficiently in accordance with the manufacturer’s instructions.
Can I shorten a PTO shaft?
Yes. Shorten the section tubes and guards by the same amount, deburr and then lubricate the tubes. Follow the manufacturer’s instructions.
When do I need a wide angle shaft?
When the implement is operating at large angles, for example during tight turns. The wide angle shaft ensures smoother operation and less wear.
Which safety clutch should I choose?
Shear bolt: the bolt breaks under overload and must be replaced. Simple and inexpensive.
Ratcheting clutch: slips with a clicking sound when overloaded and resets automatically.
Friction disc clutch: slips when overloaded and absorbs torque peaks; good for implements with a heavy start.
Freewheel clutch: allows implements with large inertia, such as mowers, to roll to a halt when the power take-off is switched off.
The implement manufacturer often specifies which clutch is required.
When do I need an adapter?
When the tractor’s power take-off and the implement’s shaft have different spline profiles, for example 6 splines and 21 splines. Please note that an adapter does not change the speed. An implement designed for 540 rpm must not be operated at 1000 rpm.
Is it worth refurbishing rather than buying a new shaft?
Often, yes. If it is only the universal joint, the fork or the guard that is worn, it is often sufficient to replace just that part.
How often should the PTO shaft be lubricated?
Usually every 8 hours of operation for knots and section tubes, but always follow the manufacturer’s service intervals. At the same time, check that the guard is whole.
Why is the guard so important?
A rotating drive shaft can cause serious accidents. Replace damaged guards immediately and never operate the machine without a guard.
Can I get help finding the right part?
Yes. Call 0304-75 10 70 or email order@olssonparts.com. A part number, measurement or a photo is all we need to help you.
