The limit pin limits the cylinder stroke length, which in turn adjusts the working depth.
Once the setting is made, the hydraulic cabin controls cannot exceed this chosen
working depth.
If necessary, the working depth can, however, be reduced hydraulically via the cab
during tilling. The cultivator is equipped with a working depth scale and indicator which
shows the theoretical working depth value. See Figure 4.
Figure 4. Working depth indicator and scale.
N.B.! The value shown on the working depth indicator is a guideline value only.
The actual working depth depends on the specific working conditions and
can be only be accurately determined by examining the results of a trial
run.
Factors affecting the acquired working depth include, e.g., the ground hardness and
weighting of the cultivator. On hard soil the plate springs supporting the discs yield
slightly, thus reducing the actual working depth.
5.2 Adjusting the weight and adding extra weights
If the cultivator is used on extremely hard ground without additional weights or the
additional loading of a seed drill drawbar, the cultivator frame and wheels may rise
above their base height. In this event, additional weights must be installed in the
cultivator frame. See Figure 5. The maximum additional weight is 50 kg per working
width metre.
