Abstract
An apparatus for application of a liquid manure to soil, possessing a frame which is adapted when towed over soil to apply such to the soil. A supply conduit, having a distal end and a proximal end is provided. The distal end thereof is adapted to be releasibly coupled and in fluid communication with a flexible supply hose which supplies the liquid-solid solution, such as liquid manure, to the distal end of the conduit. The proximal end of the conduit is in fluid communication with a manifold which thereafter via a plurality of supply tubes supplies such liquid/liquid solid dispersion to the soil. An intermediate portion of the supply conduit is flexible. A boom member at its distal end supports a distal end of the supply conduit. A proximal end of the boom member is pivotably coupled to the frame to allow pivotal movement of the distal end of the boom member in at least a horizontal plane. The pivotal coupling in a preferred embodiment further permits limited vertical movement of the distal end of the boom member to better allow direct transmittal of tensile pulling forces on the flexible supply hose to reduce the incidence of kinking of such supply hose.
