The SaltDogg TGS07 11 Cubic Foot Tailgate Spreader is a large volume commercial tailgate spreader. It features a horizontal auger, stainless steel trough, and an included concealed vibrator that allows it to spread bulk salt or a 50/50 sand/salt mix from 3/4 ton and 1 ton trucks. The spreader has a low-profile, 11 cubic foot hopper. The hopper's frameless, double-wall poly construction is durable and highly corrosion resistant. The spreader mounts to a 2 in. Class 4 hitch with patented horizontal and vertical adjustment. Its 12 in. poly spinner can cast material up to 30 ft. A 1/2 HP, 12V dual shaft gear motor is controlled by an included variable speed in-cab controller. Note: The TGS07 Spreader Extender (see "Accessories" below) is required for installation on trucks with flared tailgates.
