Three into one will go

When the swathing hoods on both mowers are closed the augers feed the material from the sides, windrowing it into one central swath. When cutting along field edges you can also close just one hood to present a clean job to the following harvester.

BiG but very agile

Driven by wheel motors and turning through a 50° angle, BiG M is extremely easy to manoeuvre and as such also offers great efficiency in small fields. An excellent front-rear weight distribution (64% : 36%) ensures that the self-propelled mower also copes perfectly in difficult terrain.
