Abstract

Prediction equations for estimating cycle time were developed for five small tractors studied under various silvicultural treatments and operating conditions. The tractors studied included the Pasquali 933, a Holder A60F, a Forest Ant Forwarder (Skogsman), a Massey-Ferguson, and a Sam4 Minitarus. Skidding costs were estimated based on the cycle-time equations. Using these equations to determine the incremental effect of log size on cost shows that hooking a 30-fP log cost $0.1 03/ft3 while hooking six logs to form a 30-cubic foot turn cost $0.234/ft3, an increase of 127 percent.
