Proceed as follows:
Press the input shaft spring button and align the grooves and splines with those of the PTO output
shaft of the tractor; see Figure 4.7 (B).
Push the driveline yoke onto the tractor output PTO shaft, release the spring button and position the
yoke of the input shaft until the spring button balls are seated onto the tractors output PTO shaft; see
Figure 4.7 (B).
To ensure that the input PTO shaft is secure, push and pull the shaft back and forth several times.
It is best practice, when fitting the input shaft to wipe a small quantity of grease (NLGI #2 Molybdenum
Disulphide) onto the splines to aid assembly and later removal.
Removal
Equipment Required
•
22mm (M14) socket or spanner
•
NLGI #2 Molybdenum Disulphide grease with paint brush/distributor
Removing the input shaft works in a reverse fashion from what is stated in the fitting section; by removing the
shaft from the tractor end first. Ensure that the PTO is disengaged, tractor engine is stopped and the handbrake
is applied before proceeding to remove the shaft.
It is best practice, when removing the input shaft, to wipe a small quantity of grease (NLGI #2 Molybdenum
Disulphide) onto the splines of the exposed shaft end to prevent corrosion.
If the machine is not going to be used for an extended length of time the input shaft should be removed
completely and stored indoors to maintain its condition.
Proceed as follows:
Press the input shaft spring button and pull back the shaft off the output splined shaft of the tractor; see
Figure 4.7 (B).
To then completely remove the shaft, remove the taper pin, flat washer and nut from the machine end;
see Figure 4.7 (A).
Refit the removed taper pin, flat washer and nut for safe keeping.
It is best practice, when removing the input shaft to wipe a small quantity of grease (NLGI #2
Molybdenum Disulphide) onto the splines at each end to aid later refitting to the tractor.

PTO Shaft Specifications
Multicut machines are primarily sold to operate at 1000 rpm, although they can be ordered and specified to
operate at 540 rpm.
DANGER!
Do not use PTO adaptors to attach a non-matching implement driveline to a tractor PTO.
Use of an adaptor can double the operating speed of the implement resulting in excessive vibration,
thrown objects, blade/driveline failures due to changes in the machines design intended use. PTO
adaptors also increase the exposed working length increasing the probability of entanglement with
external objects. If the shaft is incorrect for the tractor; contact your local Spearhead dealer for
assistance.
It is important to only operate at these speeds as a
maximum
and that the input PTO shaft is of the correct
specification for the machine and tractor. See Table 4.2 for input shaft speed options and the spline quantity
options.
