Built in Lancaster Pennsylvania, by highly skilled craftsman with decades of spreader building experience, these spreaders are crafted for daily farm-use-conditions and made of the most durable components we know of. Materials such as grade-5 bolts, greaseable bearings, oil-impregnated bronze bushings, heavy-duty size 60 roller chain (nearly 2.54cm wide), T-Rod apron chain, and hardened sprockets ensure longevity. You can judge a spreaders materials and components quality by its overall unit weight, the heavier the better. The ABI spreader weighs nearly 1/3 more than equivalently sized competitors spreaders. Now that is tangible quality you can feel!
