ABSTRACT:
The present invention is an agricultural implement for installing an irrigation system. The implement is made up of a frame structure having front and rear ends including a hitch for attaching the frame structure to a tow vehicle. An earth-excavating chute is attached to the frame structure. The earth-excavating chute has a forward earth intake end and a rearward earth discharge end. The earth-excavating chute has a longitudinal axis that is downwardly inclined such that the earth discharge end is higher than the earth intake end. A spool support attached to the frame structure supports a spool of liner material beneath the chute and between the earth intake and discharge ends and transverse to the chute longitudinal axis to allow the liner material to unwind from the spool and be covered with discharged earth during an irrigation system installation operation.
