Connecting To A Tractor
– Agricut 270
Remove the tractor drawbar, or position it to one side so it does not foul on the P.T.O. shaft; see
Figure 4.9.
Remove the two Cat II link pins. Reverse the tractor up to the machine, and adjust the lift arm height to
align with the pin holes; see Figure 4.10.
Turn off the tractor, apply the parking brake and remove the starter key.
Attach the lower lift arms to the machine using the Cat II pins. There are three available positions. Fit
each pin in the position that gives approximately 50mm clearance between the lower lift arms and the
lift arm brackets; see Figure 4.11
Refit the lynch pins.
NOTE: An insufficient amount of clearance will prevent the machine from floating correctly.
Start the tractor and raise the machine on the lift arms until the gearbox P.T.O. shaft of the machine
and the tractor P.T.O. are at their shortest distance apart.
Turn off the tractor, apply the parking brake and remove the starter key.
Adjust the tractor stabiliser chains (or bars) so there is no lateral movement when the machine is in the
raised position; see Figure 4.12.
Connect the end of the P.T.O. shaft that has the shear bolt to the machine and secure the P.T.O.
guard restraining chain to the machine; see Figure 4.13.
Connect the other end of the shaft to the tractor and secure the P.T.O. guard restraining chain; see
On the first occasion when the machine is fitted to a tractor the P.T.O. shaft may need adjusting in length. Refer
to the P.T.O. shaft manufacturer’s instructions, supplied with the shaft, for details of how this should be done.
Bear in mind that using the machine on another tractor at a later date may necessitate further adjustments or the
fitting of a new, longer shaft.
