Abstract
The hydraulic system of this invention is for operating a tree processing implement on a work vehicle so that during a first part of an operating cycle the implement is supplied by two hydraulic pumps jointly, while during another part of the operating cycle the implement is supplied by only one of the pumps. The result is that during the first part of the cycle the implement moves rapidly but during the other part it moves slowly.
