5.3 Lane marker
The disc lane markers can be centred up with respect
to the tractor. Setting: move the extension arms into
their operating positions. Adjust the disc contact point
(12.1/1) correspondingly; (depending on working width
and row distance of the drilling machine and the tractor-
lane width during lane marking).
The lane marker is switched over by means of a
hydraulic shuttle valve on the drilling machine. A single-
action control valve must be fi tted to the tractor for this
purpose.
Fine adjustment is carried out by displacing the mar-
king disc.
Centring-up with respect to tractor (12.2.1), measured
from outer share:
Working width + row distance = A

Example: 3 m operating width (B = 300 cm)
12 cm space between rows (R = 12 cm)
170 cm tractor lane (S = 170 cm)
B + R 300 + 12 = 156 cm = A

Turn the disc axle (12.1/2) to give the disc more or less
grip on heavy or light soil accordingly.
The lane markers are switched over at the forward
furrow by means of a single-action tractor control
device
... Set to “raise” at the end of the traverse – both lane
markers are now raised,
... When starting the “lower” traverse – during operation,
the control device must always be left set to “lower”
(fl oating setting).
