Pre-emergence markers
WARNING
Danger of injury
¾
Make sure before operating the pre-emer-
gence marker that no persons are present in
the danger zone.
The pre-emergence markers mark the tram
lines before the seed grows. They can also be
subsequently mounted to the coulter brackets.
The coulter brackets are hydraulically lifted and
electrically activated by the tram line control
system.
The cutting angle of the coulter discs can be
adjusted to suit the soil conditions and the re-
quested marker depth by rotating the disc angle.
¾
Simply release the bracket and rotate the
four-cornered shaft until the requested coulter
disc angle is attained. Marking should not take
place deeper than necessary.
¾
Then tighten the screws again.
