Abstract: A mobile grass seed planter having mounted thereon a frontal line of spaced water nozzles, and behind each nozzle, in a second or back row, is a row of outlets through which seed is directed under air pressure. In operation, as the planter is moved over the earth, a plurality of parallel narrow grooves are cut into the earth by the pressurized water, and the seed is then blown into the grooves. The liquid and airblown seeds are supplied to the planter via hoses from pressurized sources, typically mounted on a truck, tractor, or trailer.
