Wet Blade, integrated roadside vegetation management system, applies 2.5-gals. of herbicide per acre. Cuts brush up to 4 ins. in dia. and applies herbicide to the cut portion of the stem simultaneously. Centrifugal force runs chemical underneath the blade as it spins. Chemical stays on the bottom of the blade until it touches the very top of the stubble, where the herbicide is brushed onto the end with a wiping motion.
