B) Attaching the machine
- Attach the lower links (A) to the hitch pins and
secure with linchpins (photo 13).
- Attach top link (P) using hitch pin (D) on the 3-point
frame so that it is relatively parallel to the lower links
(A) (photo 13).
- Connect hydraulic hose (H) to the tractor’s single
acting valve (photo 13). First make sure that the
hydraulic connection is clean ; if not, cylinders may
not function correctly.
C) Adjusting cutterbar horizontal position
- Activate the tractor’s hydraulic lift mechanism and
check that the 3-point frame is lifted parallel to the
ground (photo 13A). If necessary, adjust levelling
rods (F) (photo 13).
If, once this adjustment has been made, the cutterbar
is still not parallel to the 3-point frame, level it by
adjusting threaded cylinder rod (V) (photo 13A).
D) Raising cutterbar and parking stand
NOTE : ONLY OPERATE THE PARKING STAND
(E) WHEN THE CUTTERBAR IS IN THE
VERTICAL TRANSPORT POSITION
(COMPENSATING SPRING IS
RELEASED).
- Activate the machine’s hydraulic cylinders to bring
the cutterbar into its vertical position.
- With the machine in the transport position (cutter-
bar vertical), raise the stand (E) and connect it to the
suspension rod (F) using pin (L) (photo 14).
Note : The PTO shaft must be adapted
at a later stage. Correct length can-
not be checked as long as the
cutterbar is in horizontal position.
