Abstract
A vertical shaft engine is mounted by a bracket on the side of a cart beam serving as a hydraulic reservoir. The engine drives a pump which is selectively connected by a manual valve to drive positive displacement hydraulic motors in series to rotate a bull gear. The bull gear turns a torque tube to rotate an irrigation pipe and wheels keyed to the pipe. The torque tube also drives sprockets to rotate wheels of a cart supporting the beam.
