Forage harvester and a semi-trailer
A forage harvester can work even when it is raining.
Chaff can be received from almost any grain or grass – you need to use a Forage harvester. Grass, hay, grains or corn – everything must be collected with the right attachment. Also, this harvester doesn’t have a container – you need to drive a tractor next to it or attach a sugarcane trailer made by Randon (you can find it in Sugarcane technology tab). Besides this trailer, you can also attach Agroliner HDK 302, however, its capacity is too small to what you harvest.
