ABSTRACT:
A harrow has rotary soil-working members in driving connection and spaced apart from one another to work non overlapping paths through the soil being cultivated. Between the rotary soil-working members, non rotary tines are positioned to work the strips remaining between the paths already worked. The non rotary tines are pivoted to the frame to move to and fro through the strips during travel. The rotary soil-working members are tined supports and the supports are elongated horizontal members to which arcuate-shaped brackets are attached. The brackets afford stops for the non rotary tines that are moving to and fro during operation so that the to and fro movements of the non rotary tines are limited.
