This versatile 70lb Ice Melt spreader is ideal for homeowners and professionals alike - a perfect size for every application. Made of rugged polypropylene, the 70 lb. capacity hopper wont rust, dent or crack - even in the cold. Nylon hubs on the wheels and stainless steel fasteners to prevent corrosion. The calibration dial's 90 settings allow operators to accurately calibrate for the specific type of material being applied - in any season. With its large fully pneumatic tires the PS10-70BH rolls easily and maintains constant ground contact. The fully enclosed gearbox and metal gears provide a uniform spread pattern every time and last year after year. Open and close the shutter via a solid steel linkage that works even in gritty conditions and won't fail like most cable-based designs.
