Chapin's 8620B 150-pound, tow-behind spreader saves you from reaching back to stop your spreader at the right time, wasting seed or fertilizer in the process. You don't need to strain your back to stretch, and you won't need to worry about burnt lawns because of uneven applications. Hooks on to the hitch on the back of an ATV, UTV or tractor. The auto-stop dual impeller stops spreading when you're not moving. It's constructed to handle tough terrain around your farm, field and acreage. The 150-pound hopper is made from rust-resistant poly, and it's supported on a powder-coated steel frame. There are 11 incremental gate adjustments so you can dial in your mix to fit your application. This unit not recommended for use with sand and sand mixes. Made in the USA with global materials and backed by Chapin's limited lifetime warranty. Material: Plastic.
