ABSTRACT:
A wiper bar system, transversing a tractor's path, comprises a fluid housing with open fluid channel therein, a wiper blade and a moisture absorbent wick surrounding the wiper blade. The fluid housing is mounted to the rear face of the wiper blade with a portion of the wick interposed therebetween. The spatial relationship between the fluid housing and wiper blade is adjustable by the user to control the amount of fluid/herbicide flowing from the fluid channel to the interposed wick and ultimately the amount of fluid/herbicide delivered to the portion of the wick surrounding the weed-contacting surface of the wiper blade.
