US Patent 10132050 Variable geometry bucket

A Variable Geometry Bucket for material handling, such as plowing snow. The Variable Geometry Bucket generally includes four bucket members pivotally attached to each other. A pair of double-acting hydraulic cylinders can cause the outer bucket members to rotate on a frame, which in turn moves the inner bucket members. Due to the location of the pivotal connections, the bucket members can be moved into different positions, resulting in a single attachment that can be used as a V-blade, a box plow, and a bucket.
