ABSTRACT:
A lawn treating machine consisting of a wheeled front section and a wheeled rear section hinged together by a hydraulically operated vertical hinge mechanism for steering the machine. The front section includes a hydraulically driven scattering mechanism provided at the lower outlets of a multiple-compartment hopper assembly. The scattering mechanism includes a rotating horizontal scattering disc and rotating agitating and feeding elements which feed material from the hopper compartments to the disc. The rear section carries an engine-driven hydraulic pump supplying pressure hydraulic fluid to respective hydraulic motors driving the wheels of the front section. The rear section also carries a pivotally mounted transversely extending ground-scarifying blade assembly having a plurality of sod-piercing blades, the assembly being raised and lowered by hydraulic link means. The front section carries a tank for liquid chemicals, connected to a spray nozzle assembly at the rear portion of the front section, and the spray tank is provided with a hydraulically driven liquid pressurizing pump.
