ABSTRACT:
To apply herbicide to crop escapements, the elevation and angle of rotation of a wick bar mounted to a tractor for capillary movement of herbicide to an application surface is selected to cause the herbicide-coated surfaces to contact the escapements. A lift arm bar: (1) a wick bar at one end; (2) a cross brace driven by a hydraulic cylinder aligned at an angle to a lift arm; (3) a length beyond the crossbar sufficient so that the movement of the cross brace within the stroke range of the hydraulic cylinder is enough to cause a sweep of between 12 inches and 52 inches of change in elevation of the wick bar; and (4) sufficient strength at the crossbrace to withstand at least a hundred pound weight multiplied by two ratios, which are: (a) the extended length to the brace spacing; and (b) the cosine of the angle of the lift arm from a horizontal position to the sine of the angle the hydraulic cylinder makes with the lift arm. A chain drive having a transmission ratio from the pivot axis of the lift arm to the wick bar rotates the wick bar under the control of the operator through an angle sufficient to control the flow of liquid to the wick surface.
