Installing your machine
Attaching to the tractor
Fit the machine to the tractor linkage in the standard way ensuring the correct match of linkage (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 stabilisers 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.
If necessary, shorten the inner and outer guard tubes equally (Fig. 1). 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.
