ENGLISH
3) From the Table of Longitudinal Seed Planting Distances (Table
5):
- Look for the table that lists the couple of pinions equal to the
seed planter's one;
- Seek the value of the longitudinal seed planting distance
previously calculated. Should there be two or more types of
disks that assure the same longitudinal seed planting
distance, prefer the disk with the largest number of holes.
- Move along to the left to see which ratio (A-B Fig. 22) you have to
set the gearbox with;
4) About the Seed Planter:
- Set the gearbox with the identified ratio (A-B);
- If the seed planting distance is not obtained with the pinions
(wheel C-D) fitted on the planting unit (Fig. 26), check with the
table to see if they need to be replaced or have their positions
reversed.
To move the chain, open the cover and loosen the chain (1)
by means of the lever. (2 Fig. 26); Put the chain on the
gears selected and align them. Tension the chain again by
means of the lever (2 Fig. 26) and close the cover.
- The gearbox transmission must be checked every time the
longitudinal seed planting distance is changed (see following
section).

3.16.4 CHECKING THE GEARBOX TRANSMISSION
To check the correct coupling between the gears inside the
gearbox, proceed as follows:
- lift the machine off the ground, switch off the tractor engine,
remove the ignition key and engage the parking brake;
- with one hand, turn the transmission wheel in the direction of
travel (Fig. 27);
- at the same time, with your other hand, grip the drive axle coming
out of the gearbox (F, Fig. 27) to exert a slight resistance to the
movement; make sure the axle is rotating together with the
transmission wheel;
- if the axle (F) does not turn in these conditions, the gearbox is
not set correctly; move levers A and B to engage the combination
chosen with the seed chart and repeat the check.
