CONNECTING THE PTO SHAFT
1. Separate the two halves of the PTO shaft and remove the plastic guards from both sections (Figure 12).
Release and remove retaining ring catches (1) with a screwdriver. Withdraw cone (2) down length of plastic
guard tube (3) and remove. Slide plastic guard tube from shaft; prise open retaining ring and remove from
yoke. Assembly is reverse of above procedure.
2. With the machine safely hitched to the tractor, drive forward on full R.H. lock. Stop the tractor engine and
apply the handbrake.
3. Referring to figure 13, attach the bare PTO shaft to tractor (Yoke, A) and machine (Yoke, B). With the
tractor in the fully turned position, the PTO shaft will be at its shortest compressed length. Check that there
is a minimum clearance of 25mm (1”) as shown in the diagram. This should ensure that there is no risk of
bottoming when in work.
4. Start tractor engine, release hand brake and drive forward slowly, steering to the left; observe the PTO
shaft closely when making this manoeuvre and satisfy yourself 25mm (1”) minimum clearance is
maintained throughout the steering arc. If there is no risk of bottoming, remove the shaft, fit safety guards
and attach complete shaft to tractor/machine. PTO shaft minimal engagement must be 150mm (6”). Fit
safety chains and ensure that the PTO shaft does not foul machine or tractor.
5. If it proves impossible to attach the PTO shaft with the clearance as shown in figure 13, the shaft must be
shortened. Separate the two halves and proceed as follows:-Attach bare half shaft (A) to tractor and bare
half shaft (B) to machine, with the sliding tubes side by side and parallel (figure 13). Mark the tubes so that
when cut, assembled and refitted to tractor/machine, they correspond to figure 13.
6. Clean off burrs and swarf. Fit assembled bare PTO shaft to tractor/machine and ensure that the clearance
as shown in
figure 13 is maintained. Proceed as in 4.
The inner half shaft may be plastic coated and must not be damaged.
Do not use an angle grinder.
