ABSTRACT:
An agricultural implement consisting primarily of a towed frame supported on retractable wheels, the frame having a plurality of independently adjustable spindles for setting height and angle of attack for various size rotatable discs. Each disc is staggered to reduce resistance and clogging. Each group of discs further includes descending diameter discs at each end with the angle of attack increasing with each decrease in diameter while spacing between the discs decreases as the diameters are reduced. The implement further including harrow teeth or picks located at strategic points adjacent the discs to ensure uniform soil disruption, the disc assembly being convertible from single gang to double gang assembly and may include conventional harrow teeth sets and or unique soil leveler attachments.
