Under the Canadian Governments Energy from the forest (ENFOR) program, two prototype machines for recovering forest residues from logging sites were built. The Recufor was designed to recover the logging residue left on the forest floor, comminute this material into size suitable for handling, and transport it to roadside. Some of the design principles of the Recufor were adapted for the logging residue processor (LRP) which was developed as a self-propelled machine to recover and reduce the residues left at roadside after full tree delimbing operations. The design, development and field trials of these prototype machines are covered in this report.
