ABSTRACT:
For the control of weeds in turfgrass, herbicide is selectively applied to the weeds overgrowing the height of the turfgrass after mowing. An applicator pad carrying the herbicide is drawn across the turfgrass as the pad is held parallel to the underlying ground and at a preset height just above the height of the turfgrass. For this purpose the applicator pad is supported by a skid having flat portions resting on the ground as the skid slides over the turfgrass. The preferred form of the skid for unestablished terrain is a large flat plate having an upturned leading edge portion and supporting the applicator pad behind its trailing edge. For established terrain, however, the skid preferably comprises a pair of runners near the respective transverse ends of the applicator pad, a horizontal transverse member preceding the applicator pad for uplifting horizontally extending weeds and raising the applicator pad in the event of the runners bridging a spot of high ground, and a pair of horizontal forward support bars intersecting at a draw bar and extending rearward to respective ends of the transverse member. The forward support bars form a plow for diverting foreign objects and for uplifting horizontally-extending weeds. Applicator assemblies are also disclosed for trim work.
