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.
Claims26
A rotary harrow comprising a movable frame and a plurality of rotary soil-working members mounted on upwardly extending shafts supports on said frame, driving means for rotating said soil-working members, said shafts and soil-working members being positioned side by side in a row that extends transverse to the direction of travel, said soil-working members being substantially spaced from one another to work paths and leave a strip between adjacent paths in the soil, non rotary further soil-working members positioned between adjacent rotary soil-working members, said non rotary members being pivotally connected to the front of said frame and extending downwardly to the rear to work the strips between the worked paths, said non rotary members being movable to and fro through the strips.
A rotary harrow comprising a movable frame and a plurality of rotary soil-working members mounted on upwardly extending shafts supported on said frame, driving means for rotating said soil-working members, said soil-working members being positioned side by side in a row that extends transverse to the direction of travel, said soil-working members being substantially spaced from one another to work paths and leave a strip between adjacent paths in the soil, further non rotary soil-working members connected to said frame on pivot connections, said non rotary soil-working members being positioned between adjacent rotary soil-working members and each of said non rotary members comprising a straight soil-working portion that extends downwardly to work the strips between the worked paths, each non rotary member being located adjacent corresponding deflection means connected to at least one adjacent rotary member, said soil-working portions of said non rotary members being turned by said deflection means during the operation of said rotary members and moved through the strips to work same.
