Trials to achieve optimal bucking were made with updated OSU-BUCK software in an eastern and a western Oregon location during the summers of 1993 and 1994. The commercial version of the software allows tagging of each log with bar-code identification numbers and therefore provides tracking from stump to customer. Data management is enhanced by automatic creation of input and output files in spreadsheet format. The software allows a choice of scaling rules, and accommodates multiple species while increasing measurement accuracy. The trials showed that, as with previous software, preferred-length requirements are a stumbling block to achieving the most effectiveness. Value and volume increases achieved with OSU-BUCK were moderate. Pairing a Log-Quality Technician with a faller appears to be a promising method for users of optimal-bucking software.
