Settings and adjustments
When starting-up the Disc-Roller in the field, it is very important that the machine is parallel with
the surface of the earth. The packing roller and the tractor keep the machine in an exact working
depth.
Drawbar
It is important that the top link (mounted model) or
the 2 adjusting bolts (A) on the drawbar (trailed model)
are adjusted correctly.
Drawbar height (recommended): approx. 500mm.
Disc
The Discs are adjusted up or down by a hydraulic
Master-Slave system.
It is important that the discs are regularly lifted to the top
to reset the Master-Slave system.
The depth position is readable on the scale (standard).
The sensor can be adjusted, where el. depth stop is mounted.
It is possible to over steer the electrical system by
turning off the switch mounted in the cabin, now the discs
can pass the sensor, thereby a deeper working depth is
achieved e.g. at headland and tramlines.
