    Description

    Data from field studies and a prebunching cost simulator have been assembled and converted into a general equation that can be used to estimate the prebunching cost of the Radio Horse 9 winch. The methods can be used to estimate prebunching cost for bunching under the skyline corridor for swinging with cable systems, for bunching to skid trail edge to be picked up by a skidder or forwarder, or bunching to roadside for stand cleanings and firewood sales. Costs can be determined easily with a hand calculator. The equation can also be incorporated into larger stump-to-mill desktop and mainframe computer programs.
