Part of the distance pieces may act as soil scraper. The machine is attached via a three point coupling and derrick (30). The cultivators are driven via intermediate shaft (31). An adjuster assembly adjust a roller (11) to determine the digging depth. When soil builds up between the rings (13), a scraper prevents clogging.</p> |
