Engineered for the field

Burley Iron Works builds custom silage trailers at our own shop at 3632 Overland Ave in Burley, Idaho. Owned and operated by KayC Jones & Sons, we have been fabricating farm equipment here for more than 50 years. Trailers come in 34, 36, 38 and 40-foot lengths, and every one is built to order — sized and configured for the operation that will run it. We build for dairies and farms across southern Idaho and the Magic Valley.

Each trailer carries the BIW name because we build it the way we'd build it for our own operation: heavy steel, clean welds and a design that keeps working season after season.
