The soil cultivator is especially in the form of a circular spike harrow. It has at least two implement units (2) which fold over inwards and have rollers positioned after them. The rollers (3) are swivel-connected by arms (4) to the implement units and have depth-adjusters (6,7) for the unit. Each roller is joined to its implement unit by at least two arms which have one adjustment acting as a depth-restrictor and or stop-piece and have a central adjustment (30). |
