The Pro Series concrete transit mixer’s most significant change is the redesign of the two pedestals that hold the drum. The front and rear pedestals are now lighter in weight, with fewer parts and wider access holes. The new design makes servicing the hydraulic pump easier, but it also allows for increased parts commonality. Another improvement is the steeper angle of the drums, which provides increased capacity while still allowing for quick loading and unloading. Putzmeister America Inc.
