Optimal working position is obtained when the support (K) (photo 16) is in the vertical
position and when the stop (L) is positioned in the middle of its stroke (photo 15).
If necessary, adjust tractor top link.
To finish, connect the intermediate
PTO shaft (N) to the secondary gear-
box (D) (photo 17).
II. ADJUSTMENT OF DOWNWARD PRESSURE OF CUTTERBAR AND CONDITIONING UNIT ON THE GROUND.
The downward pressure of the cutterbar and conditioning unit on the ground is
determined by the two suspension springs (O & O’) (photo 18) and correspond to a length
P = 60 mm (2 3/8") (photo 18).
The operator can, however, modify this setting slightly when working in extreme
conditions :
- soft and very wet ground :
reduce the downward pressure
of the cutterbar, reduce length
P.
- Very uneven land or working
at high speed : increase the
downward pressure of the
cutterbar, increase length P.
Adjustments should be carried
out with the cutterbar resting
on the ground and by adjusting
screws (O & O’) (photo 18). Do
not forget to retighten the
lock nuts (R & R’) (photo 18).
IMPORTANT : When operating the machine without the conditioning unit,the
compensating spring (O’) must be removed and length P adjusted to 100 mm
(4") for working in normal conditions.
The correct downward pressure of the cutterbar and conditioning unit will
prolong the life of the machine.
