Abstract:
1. A work vehicle having a fluent material spreader comprising: a variable speed right-side impeller rotationally attached to the work vehicle, the right-side impeller adapted to receive and broadcast fluent material out to a right-side material broadcast width as a function of rotational speed; a variable speed left-side impeller rotationally attached to the work vehicle, the left-side impeller counter-rotating to the right-side impeller, the left-side impeller adapted to receive and broadcast fluent material out to a left-side material broadcast width as a function of rotational speed; a right-side command input device adapted to command a desired rotational speed of the right-side impeller, wherein the desired rotational speed of the right-side impeller corresponds to a desired right-side material broadcast width; and a left-side command input device adapted to command a desired rotational speed of the left-side impeller, wherein the desired rotational speed of the left-side impeller corresponds to a desired left-side material broadcast width.
