The Allen HDX 600 hydraulically powered trowel is a double, 4-foot-diameter rider. First in the new Hydra-Drive-Extreme (HDX) series, the new trowel features all-hydraulic drive and steering, plus a 44-horsepower Kubota diesel engine. The HDX 600 uses two, 46-inch-diameter, five-blade overlapping rotors and provides rotor speeds to 135 rpm. Other features include an electrically powered spray system for retardant application and a flip-up seat and removable screens for access to power train components.
