Abstract
A rock windrower has a pair of side blade members that are elongated at fore and aft directions and are positioned to be widely spaced at one end and tapering to a narrow spacing at an opposite end. Movement along the ground with the side blade members engaging or adjacent to the ground surface causes rocks that are engaged to be moved along the tapered V-shaped frame to form a windrow. The side members include cutting blades along the lower edges. A plurality of gauge wheels on the side blade members engage the ground and support the cutting blades at a desired orientation and level relative to the ground surface.
Claims13
A rock windrower having a pair of side blade members positioned spaced apart a selected first distance at a first end, and at a second end the side blade members being spaced a substantially less second distance to form a general V-shape configuration in plan view, lower edges of said side blade members being at a level relative to a ground surface that is selected to move rocks along the V-shape as the rock windrower is moved forwardly, and a plurality of gauge wheels mounted onto the side blade members for maintaining the lower edges at the level relative to the ground surface to engage rocks on the ground as the rock windrower is moved along the ground, each of the plurality of gauge wheels being mounted on a pivoting arm pivotally mounted relative to the side blade members at a pivot connection, respectively, and an actuator for controlling the position of the pivoting arms about the pivot connections relative to the respective side blade members to change the position of the lower edges relative to the ground.
A rock windrower having a support frame, and having a pair of side blade members positioned spaced apart a selected first distance at a first end, and at a second end the side blade member being spaced a substantially less second distance to form a general V-shape configuration in plan view, lower edges of said side blade members being at a level relative to a ground surface that is selected to move rocks along the V-shape as the rock windrower is moved forwardly, a plurality of gauge wheels mounted onto the side blade members for maintaining the lower edges at a level relative to the ground surface to engage rocks on the ground as the rock windrower is moved along the ground, and a linkage between the side blade members and the support frame for raising and lowering the side blade members relative to the ground independently of the gauge wheels.
A rock windrower adapted to be moved longitudinally in a first direction, said rock windrower having a support frame and a rock windrower assembly comprising cross members, and side blade members that are mounted to the cross members, said side blade members being spaced apart a first distance adjacent a first end of the rock windrower frame, and the side blade members being spaced apart a second distance which is substantially less than the first distance adjacent a second end of the rock windrower, the side blade members being substantially upright and having lower edges that engage and move material on the ground laterally along the side blade members, and support gauge wheels mounted on the side blade members as the rock windrower moves forward, respectively, for supporting the side blade members on a ground surface with the lower edges of the side blade members at a selected relationship to the ground surface when supported on the gauge wheels, and a linkage between the support frame and the rock windrower assembly for raising and lowering the side blade members relative to the support frame.
