Abstract
A rolling herbicide applicator contains an herbicide nozzle fastened to a rigid shaft and axle at the center of a rolling disc for selectively applying herbicide to undesirable plants, while shielding desirable plants from herbicide overspray. The rolling applicator allows a user to trace a flowing outline through landscape arrangements of any shape with a steady movement as the rolling disc proceeds along the outline. The open design simultaneously provides the operator a direct and continuous view of the sprayer in operation.
Claims8
A rolling herbicide applicator for selectively applying herbicide to undesirable vegetation, while shielding desirable vegetation, the applicator comprising:
- an L-shaped rigid shaft comprising an upright length and a parallel length;
- a disc carried by said shaft, wherein a rounded opening is provided at the center of said disc and wherein a distal end of said parallel length extends through said opening and is held in place by a first connection means, thereby allowing said disc to rotate about said parallel length;
- and
- a second connection means for attaching an herbicide sprayer substantially parallel to said perpendicular length, wherein herbicide may be delivered to a selected area adjacent to a corresponding side of said disc, while said disc operates as a shield to prevent delivery of said herbicide to an opposing side of said disc.
A method of applying herbicide to undesirable vegetation while simultaneously shielding desirable vegetation, the method comprising the steps of:
- securing an herbicide sprayer to a rolling shield;
- placing said rolling shield in contact with a ground surface having undesirable vegetation;
- operating said herbicide sprayer to begin application of herbicide to said undesirable vegetation;
- proceeding along said ground surface, while maintaining said rolling shield in contact with said ground surface so that said rolling shield rotates about a shaft, whereby said herbicide is applied to said undesirable vegetation on a first side of said rolling shield, while said rolling shield simultaneously shields desirable vegetation on a second side of said rolling shield from said herbicide.
A method of applying herbicide to undesirable vegetation while simultaneously shielding desirable vegetation, the method comprising the steps of:
- securing an herbicide sprayer to a rolling shield, said rolling shield comprising a disc carried by an L-shaped rigid shaft, wherein a rounded opening is provided at the center of said disc and wherein a distal end of said shaft extends through said opening, thereby allowing said disc to rotate about said shaft;
- placing said rolling shield in contact with a ground surface having undesirable vegetation;
- operating said herbicide sprayer to begin application of herbicide to said undesirable vegetation;
- proceeding along said ground surface, while maintaining said rolling shield in contact with said ground surface so that said rolling shield rotates about said shaft;
- whereby said herbicide is applied to said undesirable vegetation on a first side of said disc, while said rolling shield simultaneously shields desirable vegetation on a second side of said disc from said herbicide.
