Ovlac Mini - PLOUGH ALIGNMENT GUIDELINES; ADDITIONAL PLOUGH ADJUSTMENTS

4.3 – ALIGNMENT
The plough should always work in line with the tractor. If not, the
tractor will tend to leave the furrow course. Check that lengths A1=A2
(Fig. 5)
Crabbing is corrected automatically in OVLAC ploughs thanks to
their oscillating cross shaft. In ploughs with fix coupling, act on the
drifting-correction turnbuckle (hydraulic in option).
The third point should be linked so that the end linked to the
plough be slightly higher than the one linked to the tractor (Fig. 6)
The third point should always be placed in the oblong hole E (Fig.
6), trying that its length does not hinder it to move while working.
4.4 – OTHERS ADJUSTMENTS
The length of the third point should be adjusted so that the frame
works in a parallel position with respect to the field since, if not, the first
bodies would plough at a different depth than the rear ones achieving
an uneven labour (Fig. 7).
For the same reason, check that the beams work vertically to the
field (Fig. 8). To achieve this, make sure that the lifting arms of the
tractor are at the same height and act on the adjusting bolts A at the
headstock (Fig. 9).
