Adjusting length
During the forward pass, the track markers mark a path in the seed
bed for the return pass. To enable this, adjust the track markers as fol-
lows:
•
On the tractor front wheels
The centre of the tractor front wheel travels over the mark.
or
•
On the centre of the tractor
The centre of the tractor travels over the mark
To the front tractor
wheels
You will need the following information:
•
Row distance of seeding machine
(= distance between seed rows)
•
Working width of drilling machine
•
Tractor track width
(= Distance from the middle of one front tyre to the middle of the
other)
> Move the machine into the working position
> Lower the track markers
Only shorten or lengthen them equally
Always shorten or lengthen track markers at both track marker legs so
that the marker disc does not damage the hydraulic tubes during the
folding procedures.
