Adjustment of impact force between rollers
(Applies to
KDC W
)
Factory set impact force of rollers should be enough. If it turned out to be too low or too high,
it is possible to correct it by modifying spring tension
S
(
Fig. 34
) with nut
N
. Modification of
impact should be performed at both sides of roller and with the same value (nut twists).

Adjusting speed of conveyor belt
Speed adjustment is possible by means of manual adjusted throttle valve. Throttle valve is
located by EURO plug of hydraulic section for hydraulic drive. Direct adjustment is possible by
means of a graduated knob. Turning the knob to the left will increase conveyor speed, while to the
right – will reduce conveyor speed.

Adjusting pressure of the cutterbar using support springs
Adjusting pressure of the cutterbar comprises changing tensioning of support springs.
To reduce pressure of the cutterbar on the ground, at the same time it is required to increase
tensioning of the springs by tightening the screw (reducing the distance
L
between the screw
head and spring catch
– Fig. 35
).
Increase in pressure of the cutterbar on the ground is caused by reduction in tensioning of
support springs, and this is done by unscrewing the screw (increasing the distance
L
between
the screw head and spring catch –
Fig. 35
).
Adjustment should be carried out with the mower lowered on the ground and retracted
cylinders.
