Title:
Multi-unit adjustable plow pulled by vehicle and having steering wheel turnable only on adjustment of plow
Abstract:
The plow system may carry as many as 10 or 14 individual plow units. All of the units are connected together by a tie rod and may be pivoted in unison relative to a main frame. By pivoting the units, they may be opened or closed to adjust the width of cut between adjacent units over a continuous, wide range. The main articulated frame includes a forward frame section with a main beam inclined relative to the direction of travel of the vehicle, and the rear frame section with a main beam in axial alignment with the main beam of the forward frame section. The forward frame section and rear frame sections are pivotally connected together for rotation about a horizontal axis to permit the system to follow the contour of the ground extending in the direction of travel. The system includes a forward furrow wheel, a rear furrow wheel, and a steerable intermediate support wheel which rides on unplowed ground ahead of the system and is steered as a function of the adjusted position of the plow units.
