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.

In a spreader for particulate material adapted to be advanced in a given direction and having discharge means for discharging the particulate material downwardly from the spreader and a rotary distributor in association with the discharge means for broadcasting the discharged material outwardly of the spreader, a particulate material deflector means on one side of the spreader and movable between first and second positions, said deflector means being located radially adjacent said rotary distributor when in said first position to intercept material broadcast by said rotary distributor and being spaced from said first position so as not to intercept material broadcast by said rotary distributor when in said second position, said deflector means having a surface against which the material broadcast by said distributor impinges when said deflector means is in said first position, and said deflector means having a nose end portion for directing the intercepted material across the front of the spreader and to the side of the spreader opposite that side where the deflector is located, said surface against which the material broadcast by said rotary distributor impinges comprising a surface which is curved in a direction circumferentially of said rotary distributor.
