WHEN YOU STOP, IT STOPS: Chapin's 89620B tow-behind spreader starts when you start and stops when you stop, thanks to the auto-stop dual impeller. Say goodbye to wasted product and burned lawns and no more fumbling for control. It's constructed to handle tough terrain around your farm, field and acreage with the oversized poly hopper, powder-coated steel frame, and 14-inch pneumatic tires. Dial in the perfect spread setting with 11 incremental gate adjustments. Backed by Chapin's limited lifetime warranty and our US-based technical support team. We recommend not using large, uneven particles like rock salt, sand or sand mixes, pelletized lime, lime or lime powders with the 89620B.
