A device for harvesting crops comprising woody material including a processor arranged to mechanically work the woody material and to feed the mechanically worked woody material to a bale-forming mechanism, the bale-forming mechanism being arranged to form a bale of the mechanically worked woody material. The present invention also extends to a method for harvesting crops comprising woody material in a continuous operation including the steps of: (a) mechanically working the woody material using a processor of a harvesting device; (b) feeding the mechanically worked woody material to a bale-forming mechanism of the harvesting device; and (c) forming a bale from the mechanically worked woody material.
