Abstract
FERIC sampled butt-damage on 25 interior felling operations. One hand- faller, 4 shear machines and 20 non-shear machines were sampled. Lumber trim losses (2 X 6-inch basis) to remove damage were predicted as a percentage of total lumber content in the tree. Predicted losses were highest for the shear machines, substantially lower for most non-shear machines and negligible for the hand-faller.

Abstract
The first part of this report deals with the theory of energy balance of a moving vehicle, which will provide the basis for future investigations taking the form of duty cycle analysis. The second part of the report examines the data of a study of power losses though oil churning in the power transmission system. Results with regular and synthetic oils at different temperatures are given

Abstract
This report is intended to be a follow-up to FERIC TN-58 "using circular saw felling heads to reduce butt splitting damage". In TR-56, shift-level production data have been collected and analysed for the Harricana and Koehring circular saw, the Denis SJ-24 twin saw, the Boreal DD-20 double-deck saw and the Lokomo cone saw felling heads. The five felling heads are compared side-by-side on various criteria such as carrier and hydraulic requirements their operational and mechanical aspects, butt splitting damage, smoothness of cut, stump height and kerf width.

Abstract
The objective of this study was to determine harvesting and processing methods that could economically utilize the stands of decadent cedar- hemlock in the interior of British Columbia. At present, existing surpluses or lack of demand for the main end products of these stands mean that they are unprofitable to harvest. Until these conditions change or harvesting modifications and incentives are introduced, it will continue to be uneconomical to harvest the stands. Recommendations are made regarding harvesting modifications and incentives.

Abstract
Mr B. Jerabek is an inventor who designed a cutting attachment for chain saws which was claimed to minimize kickback energy while enhancing cutting performance and reliability. Six Jonsereds 520 SP power heads were modified by the inventor to meet the specifications of this cutting attachment design. The technical note describes the Jerabek concept, and kickback energy, cutting speed and lubrication efficiency obtained from both laboratory and field tests.
