METHOD AND SYSTEM FOR HIGH PRESSURE LIQUID INJECTION OF TURF SEED

摘要

A turf care system and method for injecting a liquid/seed mixture into soil, such as the crown of an established turf stand, using simultaneously fired pulses of high-pressure liquid jets of the mixture shot toward the ground. The liquid, typically water, is mixed with dry grass seed before being delivered to a high-pressure liquid/seed pumping system, which uses an accumulator (60) and sequencing valve (92) to produce at regular repetitive intervals pulses of the liquid/seed mixture under high pressure. These pulses are delivered to an elongated hydraulic manifold (90) having multiple nozzles (188) pointed downwardly, which are spaced from one another and the ground by predetermined distances. This liquid/seed injection system and method for planting turf grass seeds has several beneficial results, including ease-of-use, reduced time and effort to plant seeds, and reduced disruption to the surface of the turf or soil in comparison to other methods of interseeding turf.
