The harvesting is one of the most important phases in the life cycle of Short Rotation Woody Crops and the performances of the machines depend by the crop morphology and its productivity.
A comparative trial has been carried out in a field with the same operative harvesting conditions, by a self propelled chipper Claas Jaguar on five different SRF species (Populus nigra, Salix alba, Fraxinus angustifolia, Eucalyptus occidentalis and Robinia pseudoacacia). The aim of the study was to evaluate the performance of the self-propelled chipper in function of different productive levels.
The machine performance was evaluated considering the effective work capacity (ha h-1) and the effective hourly production (t h-1). Turning times and dead times were excluded.
The effective work productivity ranged from 36.13 t h-1 to 54.73 t h-1, for Salix alba and Populus nigra respectively.
From logistic point of view the data collected brought important information about the scheduling of harvesting operations, allowing to predict the operational potential of the machine as a function of the field yield. These issues are particularly relevant, especially for the planning and management of energy basins.
