Fig. 17. Adjustment of wheel track marker.
Place the drill to the middle of the tractor. The side limiters of the lower links must be in neutral
position. Drive the machine straight on approx. the length of the tractor. Measure perdendicularly
the distance between the middle of the tractor’s front wheel track and the marker disc line. Fig. 18.
This measure should be
Mounting measure = working width – tractor wheel base
If the marker is adjusted when the drill is not mounted to the tractor the best way to carry out the
measurement is to take it from middle of the drill to the marker disc. Then the right measure is
Working width - tractor wheel base

As for the other parts the adjustment is carried out as described in the preceding chapter.
