The STABI/FRS for tractors from 300 to 500 hp is the definition of the perfect stabilizer. With a fixed-rotor system and high productivity, it is stable and strong, even on very hard ground with stones. The STABI/FRS can be used on small work sites as well as for major infrastructural work, such as on highways, parking lots and airports. The protruding rotor facilitates stabilization at depth with minimal power absorption. The crushing chamber makes it possible to work the ground to a depth of 20 in, ensuring an excellent mixing quality. The solid frame and use of wear-resistant materials provide excellent reliability over time.
