Fit the machine to the tractor in the standard way, ensuring the correct match of linkage
(category 2 linkage pins). Check that the top link is in good order and threads are well
lubricated. Use stabilizers to take any free movement out of the 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.
Fig 1 - Shortening the PTO drive shaft
a) Check shaft tube surplus length.
b) Cut surplus length from shaft tubes. File sharp edges and remove burrs.
c) Shorten shield tubes to the same length. Grease inner shaft tube and install
shield.
To fit the PTO, first clean and grease press pins on the yoke and simultaneously push
the PTO drive shaft onto 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.
