Abstract: The present invention relates to a rotary spreader where material is deposited on a rotary disc and is broadcast upon rotation of the disc as the spreader is moved. The present invention is directed to a jet action deflector which is used with the rotatable disc. The jet action deflector functions to intercept the material which is broadcast by the rotatable disc, which material would normally be directed to one side of the spreader, and redirect that material across the front of the spreader and to the other side of the spreader. The intercepted material is effectively shot at high velocity by the jet action deflector across the front of the spreader to the opposite side of the spreader. As a result, this material is spread over a wide area of the turf and is not concentrated in any particular area. The deflector may be used to prevent spreading of material on a driveway or sidewalk when the rotary spreader is being used adjacent the driveway or sidewalk.
