ABSTRACT:
An attachment for a tractor drawn grain drill is disclosed having a horizontal array of harrow tines staggered along a plurality of transverse rows with each row commonly supported by a rotatable control rod with a tine coiled portion encircling the control rod and one tine end fixed thereto while the other tine end extends away from the rod a distance sufficient to engage and till the earth when the other tine end is directed generally downwardly. Each control rod has a lever arm extending away from the rod and pivotally coupled to one or more control links so that link movement induces rotation of the control rods for pivoting the entirety of tines simultaneously between earth engaging and generally horizontal stowed positions. A hydraulic arrangement remotely controllable by a tractor operator is provided for moving the control links to raise or lower the tines and the hydraulic arrangement may further be coupled to enable or disable the grain drill. The harrow device is suspended beneath a leading portion of the grain drill with the harrow device leading edge being suspended from a hitch portion of the grain drill and the trailing edge of the harrow device being suspended from a forward portion of the main body of the grain drill. Thus, the only coupling required between a tractor and the grain drill is a hitch and a pair of hydraulic lines for actuating the hydraulic cylinder.
