Less effort needed to discharge the drum of the concrete mixer, through the big and strong little gear. The blades construction ensures easy replacement, as they are bolded and not welded. The wheels are made of solid rubber and designed to grant the maximum traction of the mixer on the ground. Shock absorber system for diesel engine cement mixers protects the structure of the frame and reduces vibrations during use. Optimal mixing and reduced mixing time thanks to a special counter bottom that pushes the material towards the sides of the drum.
