Sooner or later, all farmers face the issue of haylage, especially those involved in dairy farming, as haylage contains more nutrients, and feeding it to livestock increases milk yield. A hay baler for haylage should only be purchased with a rotor, and one with density adjustment is essential. Among the mass-market models, belt-driven rotary balers from John Deere, Klas, Vikon, and Rivier are ideal for this purpose, as are roller rotary balers from the Klas Rotocut 46 series and above, Doich Farr, and Welgher.
