Attaching To the Tractor
Fit the machine to the tractor linkage in the standard way, ensuring the correct match
of linkage (CAT 2 pins). Check that the top link is in good order and threads are well
lubricated, (as fine adjustment to height of cut is regulated by the top link). Use
stabilizers to take any free movement out of lower link arms. Before fitting the
machine to the tractor linkage you should ensure there is sufficient front weight to
ensure the front wheels are always in contact with the ground. This is most important
for safe transport and stability when turning on slopes.
Before fitting the PTO for the first time, it may be necessary to adjust the length.
There should be maximum engagement of the sliding tubes without bottoming at the
shortest operation position. To check, first connect the mower to the tractor. Pull the
PTO shaft apart and connect to the tractor PTO output shaft and the gearbox input
shaft. Hold the half shafts next to each other in the shortest working position.
NOTE – CHECK ROTATION OF OVERUN CLUTCH BEFORE CUTTING PTO
SHAFT
If necessary, shorten the inner and outer guard tubes equally (Fig. 2). Shorten the
inner and outer sliding profiles by the same length as the guard tubes. File all sharp
edges and remove burrs. Grease sliding profiles.
To fit the PTO, first clean and grease. Press pins on
the yoke and simultaneously push the PTO drive
shaft on to PTO shaft of the tractor until pins
engage.
The PTO shaft is fitted with a non-rotating safety
guard. It should be secured to the machine and
tractor with the two retaining chains provided.
Warning
Fully tighten check chains and linkage stabilisers to hold the machine rigid.
There must be no side ways movement, it is dangerous.
