DELIVERY
The machine is delivered in a partially dismantled condition. To make ready for attachment
to the tractor it will be necessary to:
Select a hard level surface
* Cut the banding straps and remove loose items. On mid-cut machines the front hood must be
bolted to the flail head.
* Fill the reservoir to capacity with oil selected from the chart on the previous page.
* Remove the lifting plate and re position the reach ram rod pin with the pin tail in its locating
hole.
* Remove and discard the transport strap connecting the flail head to the frame.
ATTACHMENT TO TRACTOR
* For electric controlled models only the base end pin of the angling ram and the rod end
pins of the lift and reach rams must be removed.
* On SI models only reverse the tractor up as closely as possible. Fit suitable return
connection to the tractor and connect the return hose before connecting the supply hose to
the tractors external services point with a suitable self-seal coupling.
* Ensure that lift ram tap is fully open.
* With the aid of a crowbar prise the flail head sideways to allow the tractor to be reversed
up
For cable controlled models only assistance will be needed to simultaneously select "Reach
Out" and "Angle Down" to allow the oil to flow whilst the arms are being moved.
WARNING
As a safety precaution to prevent the possibility of the flail head slipping sideways and the arm
collapsing on the fitter as he is prying the head sideways, a loop of strong rope or wire, with sufficient
slack to allow the required flail head movement should connect the frame and dipper - this will then
act as an arrestor in the event of this happening. Leave in position until attachment is complete.
Adjust tractor drop arms to enable the draft links to lower to within 15” (375mm) of the ground.
Remove the top link and machine yoke completely.
Reverse the tractor squarely to the front of the machine, engage draft link pins and secure.
Attach yoke to the top hitch position on the tractor ensuring the lug for the top link is uppermost.
Unlimber the machine controls and fit into the tractor cab –
refer to pages 16 &17.
Install the top link between yoke and upper hitch position on the machine. - If necessary fitting
Cat. 1 sleeves into the ball ends of the top link.
* Raise the machine on its three point linkage until the PTO shaft and the gearbox stub shaft are
as near as possible in a straight line.
