Subsurface installation of tubing
US-7524142-B2Abstract
A tractor attachment for installing tubing beneath the ground includes a frame having a toolbar to which multiple plow assemblies are coupled and spaced apart by rigid spacers. Each plow assembly includes a plow blade and a drop feed tube, mile plow blades extend downwardly in a first direction from the toolbar and the drop feed tubes extend downwardly in a second direction from the toolbar. In operation, the multi-plow attachment is lowered such that the plow blades engage a body of soil at a desired depth. The desired depth at which the plow blades engage the soil is based at least in part on the pitch of the plow blades. The tractor moves forward to cause the plow blades to create trenches in the soil at substantially the desired depth and strands of conduit (e.g., drip irrigation tubing) are fed from the drop feed tubes to the created trenches.
