A flow gate for an associated spreader comprising: a first body member including a first attachment portion and a first sleeve portion; a second body member including a second attachment portion and a second sleeve portion, wherein the first and second body members operatively attach to each other; a first flow control member received within the first sleeve portion and adjustable between an open position, a closed position, and a plurality of partially opened positions; a second flow control member received within the second sleeve portion and adjustable between an open position, a closed position, and a plurality of partially opened positions; a first locking mechanism having locked and unlocked conditions, wherein the locked condition prevents the first flow control member from adjusting and the unlocked condition allows the first flow control member to adjust; and a second locking mechanism having locked and unlocked conditions, wherein the locked condition prevents the second flow control member from adjusting and the unlocked condition allows the second flow control member to adjust; wherein the first and second flow control members prevent the flow of material from the associated spreader when both the first and second flow control members are in the closed position, and wherein the first and second flow control members allow the flow of material from the associated spreader when one of the first and the second flow control members is in the position selected from the group comprising the opened position and the plurality of partially opened positions.
