M&W^® large round hay balers are designed to take the work out of baling hay. A simple, easy-to-maintain design incorporates a fully-enclosed bale chamber, simple controls, and reduced horsepower requirements to provide years of trouble-free service and consistent high-quality bales. The fully-enclosed chamber helps minimize leaf loss, while creating a bale that cures from the inside out, to provide higher feed value in the bale. Featuring fewer moving parts than most balers, the M&W baler requires less maintenance and reduced down time. The chopper feature on the 4497SM creates finer hay silage resulting in a denser silage bale. With four sizes of balers and a wide array of productive options to choose from, M&W provides a simple baler for most any hay and silage application.
