Curved wire tines move over the soil surface to effectively uproot thread-stage weeds and break up soil crust. Dual rows of staggered, flexible tines spaced at 1 12″ apart can easily move around even mature crops and drip irrigation without damage. The vibrating action effectively brings small weeds to the surface. Cultivate once or twice a week over established crops for weed-free beds. May require two passes for optimal results. Other widths available.
