5.4.2.2 Single-Pass Harvesting of Short Rotation Crops

Willowscanbeharvestedusingcut-and-chip,cut-and-billet,andcut-and-bale
methods. The cut-and-chip method involves use of a cutting mechanism and chip-
ping mechanism designed for tougher woody material like willow (Fig. 5.29a ). The
cut-and-billet method is employed by typical sugar cane chopper-harvesters (see
Fig. 5.29b ). The chipped or billeted material is received in a trailer. Self-propelled
machines pose soil compaction problems because of their weight. The use of track-
type machine reduces compaction, but the track-type machine needs to be trans-
ported on a low loader from site to site. Further, the trailer used for receiving chips
