Patent ID: 6973885

Claim:
A mobile aerator and deep root stimulator system for subterraneously: treating plants such as trees, bushes, shrubs and the like, said system comprising: a trailer adapted to be towed to a job location near said plants to be treated; a tank for preparing and storing root treatment solution, the tank having an interior and first and second, spaced apart pipes in fluid flow communication with said interior; a pump coupled to said first pipe for withdrawing fluid from said tank and providing a high pressure source of root treatment solution; a first valve for redirecting solution from said pump back into said tank via said second pipe for mixing the tank contents; a multi-segmented probe for subterraneously injecting said treatment solution or high pressure air into the ground adjacent or proximate the roots of plants to be treated; a second valve for directing treatment solution from said pump to said probe; a solenoid-operated valve for allowing or blocking the passage of treatment solution to said probe; wherein the probe comprises: a rigid, upper segment for receiving treatment solution through a check valve; a rigid foot plate that can be manually manipulated; an intermediate segment connected via a T-coupling to the upper segment and extending downwardly to the foot plate; an aerator valve leading to the T-coupling for selectively admitting high pressure air into the probe for subterraneous application; and, a lowermost probe segment terminating in a hardened tip adapted to penetrate ground that comprises at least one outlet orifice for ejecting air or root treatment solution; and, a computer controller establishing a timed injection cycle of treatment solution for activating said solenoid-operated valve for a predetermined time interval, thereby providing a preselected dose of treatment solution to said probe for subterraneous injection.
