P.T.O. SHAFT
THE LENGTH OF THE PTO SHAFT MUST BE ADAPTED TO THE TRACTOR BEING USED WITH
THE CUTTERBAR LATCHED IN VERTICAL TRANSPORT POSITION (PRESSURE IN CUTTERBAR
LIFT CYLINDER RELEASED).
Proceed as follows to
check that the PTO shaft length is correct
when coupling the machine to a tractor for the
first time and when using another tractor.
1°
Remove
the PTO shaft and
separate
the two half transmission tubes.
2° Raise the cutting / conditioning unit to its
full vertical transport position, then release hydraulic pressure
to engage latch (
I
)
(photo 21).
3°
Set the tractor 3-point lift
to the position where the
distance
between tractor and machine PTO stub is
as short
as possible
.
4°
Connect the half transmission tubes
to their corresponding PTO stubs
(free wheel clutch on machine side,
tractor end yoke on the 540 rpm PTO for FC 240 P and on the 1000 rpm PTO for FC 280 P)
.
Hold both
shaft halves next to one another
. The outer guard tube should remain clear of the protection cone by
"a" =
40 mm (1 1/2")
(see photo H). If this is not the case, shorten the two transmission tubes and the two guard tubes
by the same length (photos
I
and J). Deburr, bevel and clean the tubes (photo K). Grease the inside of the outer
tube (photo
I
).
5°
Lower the cutting / conditioning unit to its horizontal working position
and
check that the overlap is
at least 150 mm (6")
by keeping both shaft halves next to one another. Reassemble the PTO sliding tubes and
connect the PTO shaft in place while the cutterbar is in its horizontal position.
