5.1 Attachment to the Tractor
Drawbar
Requirements
The drawbar is normally supplied with a ring hitch, which is
suitable for connection to the pickup hitch found on most
tractors in the UK.
Ensure that your tractor hitch is suitable for this type and
dimension of ring.
Ensure the capacity is a minimum of 3 Tonnes. Additionally,
the recommended minimum horsepower is 140 HP and 6
Tonnes weight.
An oil supply of at least 60 L/min @ 200 bar (8.79
Gallons/min (UK) @ 2900 psi) and a minimum electric
supply of 20 Amps @ 12v DC are required. The tractor must
be fitted with a power beyond unit.
Attaching
Hitch the tractor to the machine. Remove and store the
drawbar stand and pin. The machine should now sit
approximately level at the chassis.
Turn the tractor cautiously and ensure the tractor links etc
do not foul on any part of the machine and that there is
sufficient clearance for hoses etc. Remove links if
necessary.
Connect the brakes to the tractor and ensure correct
operation.
Release the hand brake (Fig. 7) , which is under the front
left of the chassis, and obtain assistance to check the
operation of the trailer brake cylinders when the brake pedal
is depressed.
Ensure the tractor lighting voltage is 12 v DC before
connecting the lights.
Connect the lights via the 7-pin plug stored just off centre of
the service post and confirm correct operation.
