No, Welger balers and Massey Ferguson balers are not the same. They are from two different manufacturers and have slightly different designs and features. While both manufacturers produce self-loading round balers, their designs vary in many ways. For instance, Welger balers have adjustable swaths and include a pick up for straw collection, while Massey Ferguson balers typically have fixed swaths and lack the straw pick up. Additionally, each manufacturer offers different size balers and additional features such as hydrostatic drive, auto-tie systems, and adjustable packing density.
