Shortening The Driveline - Major MR150 Operator's Manual And Parts List

recommended. Level the mower at the sides by adjusting the tractor lift links. The knives must be at the same
distance from the ground on both sides of the implement. Mount the driveline, checking that it correctly meshes
at both ends.
Consult the descriptions on the following pages for greater details. If a safety system is required, this must be
mounted from the side of the implement and not from the side of the tractor. Check that the driveline is the
correct length
The minimum coupling length must be no less than 150 mm (6 inches) in each work position. Driveline travel
must still be about 25 mm (1 inch) in the maximum coupling position. (Fig. 5.11)
These are the correct regulations for safe working conditions. If the driveline is too short and tends to slip out of
place, it must be replaced with a longer one
PTO SHAFT LENGTH
The tractor PTO shaft length may be altered to suit the
individual tractor model. When the machine is in operation, the
PTO shaft should have a minimum 1/3 engagement as shown
in the diagrams to the right . (Fig. 5.12)
Contact your nearest dealer or a specialised retail outlet if the
PTO must be replaces with a longer one, since this must
belong to the same power category and possess the same
characteristics
If the PTO shaft is too long, it should be shortened in the
following way:
•
Set the machine at a minimum distance from the tractor,
the brake the tractor and switch off the engine.
•
Separate the two halves of the PTO. Insert the female part
into the tractor PTO and the male part into the mower PTO,
checking that the position is correct by means of the fixing
pins.
•
Near the two halves of the PTO together, keeping them
parallel.
•
Using a marker pen, match mark the place where the two
halves must be shortened as shown.
•
First cut shield "1" and use part "2" as a reference to cut the
splined shaft. (Fig 5.13)
•
Proceed in the same way for the second half.
•
Trim and chamfer the two cut ends of the PTO and clean
off all swarf and shavings. (Fig 5.14)
•
Grease the two profiles and join the two halves of the PTO
together again.
•
Mount the PTO shaft and check that its length is correct as
before. The shaft must not reach the end of the tube or
project from this.
