Fig. 6.79
ADJUSTMENTS
The press wheels admit the following adjustments (Fig.
6.79):
- Working WIDTH, depending on the planting
depth.
- PRESSURE exerted by the wheel onto the
terrain.
- BEARING ANGLE of both wheels, unless using
out-of-phase press wheels, since their bearing
angle can not be adjusted.
THE PRESS WHEELS NEED TO BE CLEANED PERIODICALLY.
6.11.1.1 WHEEL’S WORKING WIDTH
Depending on the planting depth, the working width of the press wheels needs to be adjusted
so that they cover and compact the seed properly:
- PLANTING DEPTH LESS THAN 2 CM
or when THE FURROW STAYS OPEN:
the shaft sleeves A (narrow) and B
(wide) need to be assembled as shown
in picture 6.80.
- PLANTING DEPTH MORE THAN 2
CM: the shaft sleeves A (narrow) and B
(wide) need to be assembled as shown
in picture 6.81.
(*) This adjustment is valid for standard
rubber press wheels of 1’’ and 2’’.
IMPORTANT: BE SPECIALLY CAREFUL WHEN DISASSEMBLING THE WHEELS, SINCE THE THREAD
HAS A DIFFERENT DIRECTION DEPENDING ON THE SIDE TO PREVENT THE SCREW FROM LOOSE-
NING DURING WORK.
