ABSTRACT:
A plow for chiselling the earth at substantial depths, including a framework having a plurality of arcuate chisel blades mounted thereon. A towing tongue is pivotally connected to the forward side of the framework, and a hydraulic piston and cylinder system is connected between the towing tongue and the framework for pivoting the framework between a position of coplanar alignment with the towing tongue, and positions in which the framework is angulated with respect to the plane of the towing tongue. Gauge wheels are pivotally mounted on the framework for selective elevation in relation to the blades, and a hydraulic system is provided for selectively elevating and lowering the gauge wheels by pivotation on the framework. The hydraudlic system for the gauge wheels includes a transversely extending tubular control member mounted on the framework for the plow forwardly of the gauge wheels. Each gauge wheel is connected with the control member by a turnbuckle subassembly.
