Use Of The Machine
4.1
Before Connecting To The Tractor And Using The Machine
WARNING!
Ensure that all operators have read and thoroughly understood all the safety procedures.
For further information refer to the relevant sections of this manual.
WARNING!
When connecting the machine to a tractor there is a risk of personal injury. Failure to
follow the safety instructions could result in serious injuries to either yourself or others.
Therefore, when connecting the machine and the tractor you should:
Make sure the tractor cannot roll.
Make sure that the tractor and the machine have compatible category attachments.
Never stand between the tractor and the machine during attachment.
Use the hydraulic three point linkage slowly and carefully.
When carrying out an attachment you must make sure that the machine is placed on a firm and level
surface.
4.2
Connecting To A Tractor
WARNING!
The tractor must have an adequate weight and capacity to lift and carry the machine.
Local legislation governing this ratio must be observed. The correct ratio between tractor and machine
ensures correct braking functions and manoeuvrability. An incorrect ratio between tractor and machine
can be dangerous.
The pasture topper is connected to the tractor on the 3 point hitch, and will accept either CAT 1 or CAT 2
linkages. The tractor must also be equipped with a levelling box. If the tractor is fitted with a swinging drawbar,
this should be set in its shortest mode or removed completely.
The tractor should be equipped with a six-splined P.T.O. and revolve at 540 rpm.
4.2.1
Connecting To A Tractor
– Agricut 180
Remove the tractor drawbar, or position it to one side so it does not foul on the P.T.O. shaft; see
Figure 4.1.
Support the A-frame and remove the three link pins.
Reverse the tractor up to the machine, and adjust the lift arm height to align with the pin holes; see
Figure 4.2.
Turn off the tractor, apply the parking brake and remove the key.
Attach the lower lift arms and A-frame to the machine using the Cat I/II pins supplied; see Figure 4.3.
Connect the top link to the A-frame and adjust the length of the link to remove any slack and to tension
the transport strap, without lifting the rear of the machine off the ground; see Figure 4.4.
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; see Figure 4.5.
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 4.6.
Connect the end of the P.T.O. shaft that has the shear bolt to the machine.
Secure the P.T.O. guard restraining chain to the machine; see Figure 4.7.
Connect the other end of the shaft to the tractor and secure the P.T.O. guard restraining chain; see
Figure 4.8. 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.
