The discharge assembly includes a plain nozzle having a contracting bore, a shaped deflector plate positioned in front of but at an angle with the end of the nozzle, and a guard plate for restricting the product discharge angle to less than 180 degrees. Structure is provided for evenly distributing the liquid manure in a swath about ten yards wide.
