Thanks to the Heuling Chaff spreader, chaff as well as shrivelled grains are spread over the full cutting width of your combine.
Ever increasing cutting widths and more efficient and harsh threshing systems (more short straws) produce a thick matt of material behind the sieves.
If unspread, this heavy swath of chaff will hinder following cultivations and the establishment of the next crop (competition with weeds and volunteers).
