ABSTRACT:
A minimum tillage rotary hoe includes a tool bar mounted transverse to the direction of field travel. Projecting rearwardly from the tool bar are a plurality of rotary hoe support arms each having a single, uniform diameter, multi-tined rotary hoe affixed to the end thereof. The rotary hoe members are staggered to define a forward row and a rear row of hoe members, each row defining generally a separate, single axis of rotation. The axes of the rows are separated by a distance less than the diameter of the rotary hoes but greater than about 0.8 the diameter of the rotary hoes. Separation is considered critical in order to render the hoes self-cleaning. Self-cleaning of field trash is effected by movement of adjacent hoes and more particularly the tines of adjacent hoes past one another to clean out the trash.
