4.13 Track markers
The hydraulically actuated track markers alternately
mark the soil on the right and left hand side of the
machine. The track marker lowered into work creates a
trace as guidance for the tractor operator for correctly
driving the next bout when turning at the headlands.
After having turned the tractor operator drives centrally
over the trace.
The track markers are connected with the hydraulic
system for
• the integrated transport wheels
• the packer coulter frame and
• the star wheel.

When shows the symbol (Fig. 70/1),
the lifting of transport wheels, packer coulter frame and
star wheel automatically releases the switching over for
the track markers.
For passing obstacles the track marker lowered into
work can be folded in and out in the field. When,
however, the track marker hits a firm obstacle the
overload safety device of the hydraulic system reacts.
The hydraulic ram gives way to the obstacle and in this
way protects the track marker from damage.
