The circular spike harrow (2) has a gear casing (3) and adjacent rotary implements (4) with trailing rollers (5) and drill (6) with seed-container (7). The circular spike harrow consists of several preferably two directly adjacent gear-casings (8,9) or circular spike harrow units (10,11). The gear casings or units can each be swivelled (15) on horizontal axles (12,13) or in a vertical direction (14) from an operating into a folded-up position. In the folded in position, the gear casings or harrow units enclose, together with the seed-drill, the seed-container positioned on the circular spike harrow. |
