CH27 DMR GENERAL DESCRIPTION AND INTENDED USE OF THE CHIPPER FARMI CH27 is a disk chipper for tractor- mounted operation. As the chip size is adjustab- le, the chipper can be used e.g. for the producti- on of chips to be used for landscaping or for bio energy.
CH27 DMR DESCRIPTION OF WORKSITES A worksite with a level and firm surface should be used when chipping. Clear any small brush and stones from the worksite. The material to be chipped should be as clean as possible - make every effort to keep soil or stones from entering the chipper.
