4. Lifting mechanism adjustment
The mower can be raised by the tractor 3-point linkage.
As the mower is raised, the cutterbar is automatically
locked in the horizontal position.
Adjustment to secure this horizontal position is made by
set screw (V) which should always be secured by lock
nut (E).
When the mower is in the working position, the cutterbar
can float at an angle up to 20°
above and below the
horizontal.
Plate (C) limits the amount of angle raised to avoid
damage to the pitman.
The total angle of movement of the cutterbar through
40° enables this to follow wide differences of ground con-
tours.
5. Angle of cut adjustment
This adjustment is made by lengthening or shortening
the tractor top link. Should the hay occasionally block
the cutterbar, do not hesitate to adjust the fingers down
towards the soil.
For certain tractors, a short top link is required. This is
available as optional equipment (part No. 100 6020)
In work, the tractor hydraulics should be in the free
floating position.
