Abstract	This paper shows how ten easy-to-use linear skyline thinning production rate equations were obtained by transforming existing but more cumbersome turn time equations using the THIN simulation model [11). The equations provide reasonable approximations of delay-free hourly production for several cable yarders operating skyline thinnings under a variety of conditions. The equations have been limited to three independent variables which can be influenced by management decisions. The independent variables are relatively easy to obtain and include: cut volume per acre, average slope yarding distance, and average log volume. The production equations which were linearly regressed for user simplicity have an inherent source of error since some of the data is nonlinear. A log bucking model is presented which aids in the determination of average log volume. Suggestions for future transformations are offered.
