Skim coulters
There are three ways to adjust the skimmers.
Lateral to the plough body by turning the cranked
stalk.
The clearance in front of the bodies by turning the
guide plate around (
21/4
) and by turning the cranked
stalk.
The working depth by shifting the skimmer on the
stalk up or down.
The red markings on the toothed segments (
21/3
)
denote the standard basic adjustment.
When fitting the toothed segment at the bottom (
21/
1
) and the thrust piece (
21/2
) make sure that the
numbers stamped on are facing upwards.
Trash boards
The trash boards are supported from the rear by
adjustable bolts (
22/1
) which should be resting
against the plough leg. The front of the trash board
should be resting on the mould board. There are
slotted holes provided at the holder bracket for
height adjustment.
Subsoilers
Due to stability problems it is not permitted to store
the plough resting on the subsoiler units. Remove
shear bolts (
22/3
) and turn subsoiler rearwards out
of way. The shear bolts are provided as overload
protection. In stony conditions the use of subsoilers
is not permitted. Depth adjustment is by means of
Disc coulters
The depth is adjusted on the notched segments
(
23/1
).
There should be a minimum clearance between the
disc bearing housing and the ground of apprx.
5 cm
(2 ”) to avoid excessive wear on the housing.
To obtain clean work the slacken bolts (
24/2 & 24/3
)
must be set, so that the cut is apprx.
2 – 4 cm
away from the furrow wall (fig.
23
).
Lateral movement of the disc is restricted by the
collar (
23/2
). Make sure that the collars are always
properly tightened.
