– OTHER ADJUSTMENT
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

For the same reason, check that the beams work vertically to
the field (Fig.12). 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.13).
