How to Correctly Size Your PTO Shaft for Your Implement

Due to the huge number of tractor models and implements such as the Rapid sprayer, there is no such thing as a one-size-fits-all PTO shaft.

Tractor models vary in the dimensions between the bottom link arms and the PTO shaft output and so do implements resulting in a need to adjust the length of your PTO shaft to ensure safe operation prior to the first use.

Skip to the following steps:

Measuring Your Shaft for Correct Length

1. Hitch your implement to your tractor using the 3PL arms and raise it to the height where the PTO output shaft on      the tractor and the implement align horizontally with each other.
2. At this point they will be closer together than when the implement is resting on the ground;Measure from the groove which runs around the shaft on the tractor to the same position on the implement and take note of this measurement;
3. Take the new PTO shaft and remove the safety guard from either end
4. Push the two halves together so the shaft is at its shortest length and measure from one locking pin to the other, taking note of this measurement;
5. The required shaft length is the first measurement (from groove to groove) minus a minimum of 76mm (3") to allow for disconnection from the tractor. If the shaft is already shorter than this, ensure that a minimum of 50% of total shaft length overlaps when in operation.

Cutting & Cleaning Your Shaft

Amount to cut off shaft:

Length of the new shaft (from step 4) - the groove to groove measurement (from step 2) + 76mm = Cut-Off Total
Then, take the cut-off total  and cut half of this measurement off each end of the shaft.
Cut half of the cut-off amount off both ends of the shaft using a hacksaw or metal saw. Remove burrs using a file from the inside and outside of the cut ends. Grease both ends of the shaft and slide them together to the shortest length;
It is now necessary to cut the safety guard tube to length to match the now shortened shaft. Follow the steps below.

Zuschneiden der Schutzeinrichtung auf Länge

1. Cut the same amount off both safety tubes as you did in step 7 to the shaft ends using a hacksaw. Deburr ends and remove any plastic shavings;
2. Re-install shaft safety guards to shaft ensuring they have locked into place.

Fitting & Testing for Correct Fit

• Install PTO shaft onto tractor and implement while shaft is horizontal and at its shortest length. If you cannot fit the shaft at this point as it is too long, it will need to be shortened further;
• Without running the PTO, lower the implement to the ground and check the angle of the shaft and universal joints. This angle should not exceed 25 degrees at rest;
•  Raise the implement to the maximum operating height and check the angle of the shaft and universal joints. This angle should not exceed 17 degrees for continuous operations;
• Lastly, check the overlap of the shaft ends exceeds 50% of the total length of the shaft operation to prevent premature failure of the shaft.
