15. PTO SHAFT RESIZING
Safety: Ensure tractor & machine is stopped & keys out of ignition before carrying out any work. If you
are not confident in carrying out the work consult your local supplier or mechanic.
Most PTO driven implements are supplied with a standard sized PTO shaft. As all tractors vary this
often means cutting it down to size. Always replace worn or damaged PTO shafts.
Attach the machine to the tractor without the PTO shaft, raise the linkage so the PTO shaft is level/
horizontal. Measure the length between tractor PTO and the machine’s shaft. If the compressed
(closed) PTO shaft length exceeds the one measured here then the driveline will need to be cut.
1.
PTO length adjustment, first remove PTO shaft shielding.
2.
Shorten the driveline tubes to proper equal lengths.
3.
Tidy edges of the drive tube with a file and clean all fillings from the tubes.
4.
Shorten the equally long guard tubes to the same length as the driveline tubes.
5.
Grease the internal driveline tube.
6.
Fit the guard on the shaft.
7.
Make sure that the length allows for at least 16cm (6 inches) of overlap.
