Semi-pneumatic tire

Gandy introduces an eco-friendly 12-inch semi-pneumatic tire option for its 24 and 36-inch precision lawn drop spreaders. Made from recycled rubber, it features a puncture-proof solid rubber tire mounted on a black, rugged polypropylene center, made from recycled plastic as well. Weighing nearly 4 pounds and 1 ½ inches wide, these 12-inch semi-pneumatic tires provide a visible stripe in the turf, allowing the operator to easily mark the area where fertilizer, granular chemicals or seed has been previously applied ensuring optimal accuracy and productivity.
