20090294555 | Rolling herbicide applicator with an adjustable shield - A rolling liquid herbicide applicator with an adjustable shield is attached to a hollow pole having an adjustable width protective shield mounted to one end weighted, textured wheels for rolling over most terrains are attached to the adjustable width protective shield. On the opposite end of the hollow pole handle is a trigger. When the trigger is activated, an internal trigger stick is moved down through the hollow pole, thereby causing a āCā piece to move upward. This upward movement pushes on a hard flat disk. The movement of the hard flat disk causes pliable cap center to move. The gravity flow of liquid herbicide from a liquid herbicide container causes the liquid herbicide to move through a tube and nozzle assembly. The adjustable width protective shield over the nozzle prevents overspray and accidental contact of the liquid herbicide on healthy desired vegetation. | 12-03-2009 |
