Abstract:
1. 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.
