APPARATUS FOR CONVERTING A CHISEL PLOW TO A PLANTER Abstract of the Disclosure Apparatus is provided for readily con- verting a conventional pull-type implement such as a chisel plow into an effective planter. The conversion assembly includes a furrow opener such as a narrow shoe located adjacent the lower end of the chisel shank, along with a trailing seed delivery tube and a pivotal furrow-closing press wheel or the like. A four-bar adjustable linkage assembly serves to operably couple the shank and press wheel so that the wheel is shifted downward- ly in response to limited upward shifting of the shank, whereby the wheel is maintained in opera- tive contact with the earth during use. The wheel also serves as a gauge stop for maintaining proper furrow depth, and the linkage adjustment permits selective setting of the wheel for different furrow depths. The conventional curvilinear chisel shank acts as one of the arms of the link- age assembly, together with the shank assembly bracket and a pair of links provided as a part of the conversion apparatus.
