Model 425 is a twin auger vertical feed mixer with a mixing capacity of 620 cu. ft and it can hold a maximum load with a heavy ration up to 15,500 lbs. The side discharge or front center flat sliding conveyor feed out of either side. Fixed or adjustable incline conveyors are optional. Twin matching single flighted augers with several knife options are available for faster mixing and processing of long fiber material. This unit is available in either truck, trailer or stationary. Its low profile allows several types of loaders to input feed without clearance concerns. The trailer model can be operated with a 110 horse power or larger tractor. Twin screws are powered by a reliable, low maintenance PTO-driven, planetary gearbox. This feed mixer is for medium-sized dairy, cow/calf, stocker and heifer operations.
