ABSTRACT:
A soil cultivating machine comprises two transverse rows of fixed tines and three transversely extending rollers. The front roller has discs which cut parallel slits in the soil. The two following rollers have transversely extending releasable blades mounted on angle-irons which form shallow V's pointed in the direction of the rollers' rotation and which are twisted about 90.degree. from their outboard ends to their centers. The rollers are drivingly interconnected by a chain transmission so that the middle roller rotates slower than the other two and the rear roller rotates faster than it would if freely rotating on the ground. The tines are in rows between the rollers and their depth of soil penetration relative to the underlying soil is adjustable. The rollers are mounted on a generally horizontal framework which is adjustable, however, so it can be inclined slightly either forward or aft to increase or decrease the penetration of the front roller's discs.
