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 only 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.
The tractor should be equipped with a double acting spool valve with a minimum flow of 30 litres/min.
4.2.1
Connecting to a tractor
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.
Remove the two Cat II link pins, and the Top Link Pin; see Figure 4.2.
Reverse the tractor up to the machine, and adjust the lift arm height to align with the pin holes.
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; see Figure 4.3. Adjust and attach the Left Hand
Lift Arm using the tractor Levelling Box if necessary. Refit the lynch pins.
Attach the Tractor Top Link to the single hole in the top of the Headstock; 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.
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 4.5.
Remove the Parking Leg securing Pin, lift Parking Leg, and replace pin in leg lower hole so that Parking Leg
clears ground; see Figure 4.6.
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 4.7.
Connect the other end of the shaft to the tractor and secure the P.T.O. guard 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.
Connect the Hydraulic Hose fittings to the Tractor Spool Valve; see Figure 4.9.
Unpack the Transport Latch Pull Rope, and attach it to a suitable point on the tractor, that will be in easy
reach of the operator from the tractor seat; see Figure 4.10. Ensure the rope will not foul or catch on the PTO
shaft, the tractor wheels, the tractor lift arms, or any other moving part.
