Abstract
A spreader including a feed gate having a feed gate opening is provided. The area of the feed gate opening may be varied to adjust the spread pattern and material distribution to accommodate different speeds at which the spreader is operated, and different materials which may be spread. Such adjustment is accomplished by linearly sliding a spread shift plate having a wide and narrow section across one end of the feed gate opening, to open or close off the end portion of the feed gate opening. Such adjustment also varies the area of the feed opening in the spreader hopper.
