Agricultural additive dispensing apparatus
A ground working apparatus for dispensing an agricultural additive to the soil is provided. The apparatus is mounted to a tool bar that is operable to be towed across an agricultural field. The apparatus includes a coulter blade in combination with a knife element, and a conduit attached thereto operable to dispense the agricultural additive in the soil. The knife element and the coulter blade characterize a gap therebetween. The gap is defined by a forward edge of the knife element having a radius of curvature that is less than a radius of curvature of the coulter blade. The conduit in interchangeably attached by at least one conduit mount plate at the knife element.
1. A method of operating a ground working apparatus configured to dispense an agricultural additive to the soil, the method comprising the steps of:
splitting the soil with a coulter blade supported from the tool bar and configured to engage the soil;
working the soil with a knife element positioned rearward from the coulter blade relative to the forward direction of travel;
dispensing the agricultural additive to the soil though at least one conduit mounted at the knife element;
utilizing at least one conduit mount plate configured to attach the at least one conduit at the knife element, wherein removal of the at least one conduit mount plate and at least one conduit from the implement does not cause removal of the knife element from the implement;
providing a swing arm pivotally supported from the tool bar and in rotational support of the coulter blade; and
allowing a support arm having a forward end and a rearward end relative to the forward direction of travel, wherein the forward end of the support arm is affixed to the swing arm, and wherein the rearward end of the support arm is mounted at an upper end of the knife element, wherein the rearward end of the support arm includes a first pair of arm openings in general vertical alignment and generally parallel to a second pair of arm openings located adjacent thereto, and wherein the upper end of the knife element includes a first elongated knife opening located adjacent and generally parallel to a second elongated knife opening, each first and second knife openings extending in a generally vertical direction, and wherein one of the first and second knife openings is configured to align with one of the first and second pair of arm openings of the support arm so as to receive a fastener therethrough operable to variably position the knife element along a length of the support arm.
2. The method of overaling a ground working apparatus of claim 1 , wherein the at least one conduit is only fastened by the at least one conduit mount plate at a rearward edge of the knife element.
