ABSTRACT:
As the applicator is propelled about the surface to be treated, hollow spikes called tines or tongs are alternately thrust, vertically downwards below the surface and withdrawn vertically upwards. A bulk supply of treating liquid is maintained separate from the applicator, so the applicator is more maneuverable and less bulky. The supply is pressurized and supplied to the applicator via a high pressure hose line. The drive for reciprocating the tongs also powers a flow-dividing valve, which supplies the treating liquid to each of the tongs in turn, so that each tong liquid injects only when that tong is under the ground surface.
