FERIC compared three harvesting systems (full-tree, tree-length, and cut-to length) on a clay site in northwestern Québec. None of the systems limited rutting to below the acceptable target level; however, cut-to-length harvesting (using a three-machine system) showed slightly better results than the other two systems.
European harvesters and processors have generated a lot of interest in Eastern Canada. This technical note reviews their current configurations, major components and suitability to Canadian logging systems.
The Forest Engineering Research Institute of Canada (FERIC) monitored and evaluated an enhanced bucking trial. The recovery of veneer bolts, stud sawlogs, pulpwood, and hog fuel manufactured from measured short logs were compared to those revcovered from enhance-bucked long logs. This report also presents productivity and cost information.
The Forest Engineering Research Institute of Canada (FERIC) examined the measuring accuracy of common harvesters and processors operating in British Columbia and Alberta. The results showed large variations in length and diameter performance of the machines, which was attributed partly to differences in emphasis placed on measuring accuracy at the harvesting site. Other factors affecting measuring accuracy included variation in tree characteristics, lack of properly calibrated measuring systems, and wrong target lengths programmed in the measuring system's computer. Based on the findings, FERIC made suggestions to improve measuring performance.
