Abstract: A sliding gate type outlet port for a semi-liquid manure spreader is presented. The spreader with which the gate is used has an open topped tank of triangular cross section supported on a tractor drawn trailer. The power takeoff from the tractor is coupled to a shaft extending internally the length of the tank near the bottom.
