Hammerless ripper system using the MTGtwist fixing solution. The system allows for easy extraction of the pin and has a standard shaped square hole. The MTGtwist retainer is made from elastomet and polyurethane. The MTG plug prevents the square hole from becoming filled with soil. The stabilization surfaces of the fitting system provides improved distribution of forces while working and it keeps the tooth firmly in place. This system minimizes breakages, even in extreme applications.
