Abstract: A method of pest control for burrowing animals involves loading a machine-conveyed dispensing apparatus with a fumigant product, and using the machine to make one or more passes across an area of ground beneath which the burrow system is situated. A ground engagement tool of the dispensing apparatus is engaged in the ground to pass through or nearby sections of the burrow system, and fumigant product is dispensed into the ground behind a leading portion of the ground engagement tool. Fumigant is widely spread over the burrowed area of ground for effective results, while the human exposure and manual effort associated with conventional hand-placed fumigant techniques is greatly reduced.

Abstract: A shank and replaceable tip of a ground working implement are defined from flat plate which is cut by laser or similar or is stamped to provide interconnecting elements between the replaceable tip and the lower end of the shank. At the lower end of the shank is provided a pocket defined by a recess cut into the lower end and a pair of plates welded on respective sides of the flat plate so that the projection of the replaceable tip extends into the pocket to hold the tip in place. This allows a rugged construction of the tip and various designs of tip can be manufactured simply by reprogramming the cutting process. A guide surface is mounted on the front plate of the shank with that guide surface defining a channel member with a leading edge increasing in radius of curvature from the lower end of the shank upwardly to a top of the guide surface spaced upwardly from the ground. This increase in width of the guide surface assists in discarding trash.

Abstract: Apparatus for seed and fertilizer placement in the ground comprises a knife followed immediately by a first tube for depositing fertilizer and a second tube spaced therefrom for depositing the seed. The second tube can be adjusted horizontally and vertically and particularly to a position scraping the side of the furrow formed by the knife to deposit the seed at the side. A packer wheel mounted on the same support as the second tube follows the second tube and runs in the furrow to press down soil over the seed and fertilizer. The packer wheel is rotationally molded from polyethylene.
