ADJUSTMENTS
There are two types of seed pressing
wheels:
- RUBBER: for delicate seeds
that may break when compac-
ting the earth. (Fig. 6.108).
- STAINLESS STEEL: for not
very tilled or muddy terrains
(Fig. 6.109).
IF THE METERING UNITS HAVE V-SHAPED PRESS WHEELS WITH SHORT CONNECTING ROD (SEE
6.11.1 V-SHAPED REAR PRESS WHEELS – PROSEM K), THEN THE METERING UNITS CANNOT BE
EQUIPPED ALSO WITH SEED PRESSING WHEELS.
6.16 TRACK ERASER (OPTIONAL)
Track erasers can be adjusted:
A. Horizontally, along their support.
B. Vertically, so the working depth of the tine coulters can be adjusted.
To modify the position of the track eraser:
1. Loosen the xing nuts (1, Fig. 6.110).
2. Place the track eraser at the desired position.
3. Tighten the nuts to x the position of the track eraser (1, Fig. 6.110).
ADJUST THE TRACK ERASERS HORIZONTALLY SO THAT THEY COINCIDE WITH THE TRACTOR’S
WHEELS. ADJUST THE TRACK ERASERS VERTICALLY SO THAT THEIR WORKING DEPTH IS ENOUGH
TO ERASE THE TRACTOR’S TRACKS (FIG. 6.110).
