Oxbo worked with customers around the country to design and develop the first self-propelled merger, the Oxbo 4334. The Oxbo 4334 offers all of the traditional benefits of merging--low ash content, fewer rocks in the windrow, more consistent windrows, and the ability to achieve hay in a day--with new benefits, unique to the self-propelled design with the pickup heads in front: increased forage quality, unprecedented operator control and comfort, and high in-field capacity.
