Design Specifications

The cones are comprised of plastic material and the steel blades are embedded in it. It has a single row and is operated by a single person in a push and pull operation. It has two conical rotors mounted in tandem with opposite orientation. Smooth and serrated blades are mounted alternately on the rotor to uproot and bury weeds when the rotors create a back and forth movement. Each cone has 6 serrated blades and 6 plain ones, each of 2 mm in thickness. Design Specifications
