Abstract

In an agricultural drill having a frame plurality of pairs of furrow opening disk equipped supporting arms and pressure wheels are connected in trailing relation with the frame. A dry soil parting share is vertically adjustably connected with the respective pair of disk furrow supporting arms forwardly of the furrow opening disks and in the direction of disk travel so that as the drill is moved forwardly the share removes dry soil from the travel path of the furrow opening disks.

Claims

1. An agricultural drill having a frame and a pair of trailing arms pivotally connected with the frame in trailing relation for vertical pivoting movement and supporting furrow opening seed planting disks forwardly of a press wheel and maintained at a selected elevation with respect to the surface of the earth by a depth control strut, the improvement comprising:

soil parting means disposed forwardly of said furrow opening disks;

telescoping sleeve means including an outer sleeve and an inner sleeve connecting said soil parting means to said arms for maintaining said soil parting means at a selected elevation relative to said furrow opening disks, said soil parting means including a pair of opposed forward disks journalled on horizontal axles fixed to the depending end portion of said sleeve means for respectively moving dry soil laterally with respect to the center line of travel of said furrow opening disks;

pin means securing said sleeves in a selected telescoped position; and

,

means including a clamp for connecting said sleeve means with said arms,

said clamp means including a pair of links secured to opposing sides of one said sleeve for contiguous contact with an intermediate portion of the inwardly disposed surfaces of said arms, a pair of clamp members extending transversely of one end portion of said pair of links and an intermediate portion of said arms in respective overlying and underlying relation, and, bolt means joining said clamp members in arm gripping relation.
