Abstract
A fertilizer applicator assembly for use with a chisel plow includes a diverter shoe located in the root zone of the crop, above the tillage point of the plow. The diverter shoe closes the furrow formed by the plow shank and forms a lateral pocket in the soil for distributing a band of particulate fertilizer behind and to the side of the shank.
Claims17
Apparatus for tilling soil while distributing particulate fertilizer comprising:
- a shank adapted to be pulled in soil in a use position and extending below the depth at which it is desired to distribute the fertilizer;
- a tillage tool mounted in front of said shank for loosening soil at least at a desired depth;
- a fertilizer delivery tube including a discharge opening and mounted behind said shank for delivering fertilizer through said discharge opening;
- and a shoe extending behind said shank, said shoe including at least one wing extending laterally and rearwardly of said shank, said wing gathering soil loosened by said tillage tool and urging said soil into the furrow behind said shank, said wing further extending downwardly proceeding away from the shank both laterally and rearwardly to compact loosened soil laterally adjacent said shank to form a horizontally elongated pocket sloping laterally downwardly;
- whereby said fertilizer is delivered laterally into said pocket formed by said wing.
An integral weldment adapted to be assembled to the rear of a shank of a chisel plow, said chisel plow including a tillage tool mounted in front of said shank for loosening soil, said weldment comprising:
- a fertilizer delivery tube having a lower portion formed into a width approximately the width of said shank and defining a discharge opening;
- a diverter shoe welded to said delivery tube and including a wing adjacent said discharge opening and extending laterally and rearwardly of said delivery tube and adapted to engage loosened soil passing around said shank in use, said wing gathering said loosened soil and moving it behind said shank, said wing further compacting said soil vertically to form a pocket in said soil, whereby said fertilizer stream passes through said discharge opening and into said pocket formed by said shoe;
- and a mounting plate rigidly connected to said diverter shoe and adapted for mounting said weldment to said shank at an adjusted height above said tillage tool and to the rear of said tillage tool.
