5. ESTIMATING LOGGING UNIT COSTS
The production rate, P, in cubic meters per hour is P = V/T where V is the volume per tree, m 3, and T is the time per tree, hr. The unit cost of felling is UC = C/P where C is the machine rate for felling and bucking and P is the production rate. EXAMPLE: A power saw and operator cost per hour and the time to fall and buck a tree is
