5.3
Attaching the machine
Attachment of the machine should be performed on a firm level site - the procedure for attachment is as follows;
Figure 5.3
Remove or reposition any tractor drawbar so it does not foul on the PTO shaft.
5.3.1.1
Remove the two Cat I / Cat II link pins, and the Top Link Pin see Figure 5.3a. If necessary support the
5.3.1.2
‘A’ frame whilst doing this.
Reverse the tractor up to the machine and adjust the lift arm height to align with the pin holes. Turn off
5.3.1.3
the tractor, apply the parking brake and remove the starter key.
Attach the lower lift arms to the machine using the Cat I / Cat II pins.
5.3.1.4
Adjust and attach the Left-Hand Lift Arm using the tractor Levelling Box if necessary
5.3.1.5
Refit the lynch pins.
5.3.1.6
Raise the
‘A’ frame and fit the top link. Adjust the length of the link to remove any slack and add
5.3.1.7
tension to the transport strap, without lifting the rear of the machine off the ground.
Start the tractor and raise the machine on the lift arms until the gearbox PTO shaft of the machine and
5.3.1.8
the tractor PTO are at their shortest distance apart.
Turn off the tractor, apply the parking brake and remove the starter key.
5.3.1.9
Adjust the tractor stabiliser chains (or bars) so there is no lateral movement when the machine is in the
5.3.1.10
raised position.
Identify the end of the PTO containing the shear bolt and connect this end to the machine. Fasten the
5.3.1.11
guard check chain securely.
Connect the other end of the shaft to the tractor, once again securing the guard
‘check chain’.
5.3.1.12
With the PTO shaft correctly connected, raise the machine to a safe transport position. Ensure a
5.3.1.13
clearance of at least 100mm between the underside of the shaft and the body of the machine whilst in
the transport position.
Lock the ‘lift-arm-stop’ in this position.
5.3.1.14
CAUTION: Raising the tractor lift arms too high may cause damage to the PTO shaft if the tractor was to drive
over any bumps and the machine was to bounce on the lift arms.
Check that there is no lateral movement on the machine when it is in the raised position; adjust the
5.3.1.15
stabiliser chains/bars if required.
On the first occasion when the machine is fitted to a tractor the PTO shaft may need adjusting in
5.3.1.16
length. Refer to section 5.4.1. below. Bear in mind that using the machine on another tractor later
may necessitate further adjustments or the fitting of a new, longer shaft.
WARNING:
Read all the safety instructions carefully before driving on the public road and always comply with
the local law concerning lights, warning and safety signs. The driver and/or the owner of the machine
have the responsibility of complying with the local Road Traffic Acts.
Always ensure tractor manoeuvrability is not adversely affected by any attached machinery; the steering axle of
the tractor should be loaded with at least 20% of the tractor
and cutting implement’s combined dead weight. See
Safety section.
DANGER:
The carrying of passengers on the machine is strictly prohibited.
