11.4 Knife roller
11.4.1 Working depth of the knifes
The working depth of the knifes (M1) will be adjusted by means of the pins
(M2). Therefore the pins (M2) above the support plate (M3) will be fitted into
one of the free holes of the carrier arms (M4). By means of the screw (M5)
the carrier arms (M4) will be swung into the required position. After fitting and
securing the pin, the screws will be turned a little anti-clockwise, so that they
are unloaded.
11.4.2 Giving way of the knifes
The giving way of the knifes (M1) to the top is limited by the pin (M6). If requi-
red a low making way to the top is admitted.
11.4.3 Adjustment of the knife frame
When the range of adjustments by means of the pin (M2) is insufficient, the
knife frame (M7) can be positioned higher in relation to the carrier arms. The-
refore the bolts must be removed from the holes (M8) and the knife frame re-
positioned.
In extremely sticky or light soils it is recommended to adjust the knifes in a
higher position. This will be done by re-positioning the knife frame.
