The powerful unit for effective soil stabilisation * The tractor-towed stabilizer WS 220 is designed to effectively improve and harden soil at a working width of 7 ft. 1 in. (2.15 m). * It can be used to make soil both compact and suitable for construction and also to create load-bearing surfaces. * It can be attached to any standard tractor in the higher performance segment by means of the standardized three-point hitch. * The double-sided, mechanical drive of the milling and mixing rotor allows for an effective power transfer. * The practically designed mixing chamber and the optimum contact pressure of the rear milling drum flap guarantees consistent and homogeneous mixing results.
