    Small diameter timber offers unique challenges for resource managers. Soil disturbance, residual stand damage, and high equipment capital are often associated with using large logging equipment to extract this timber. In an ongoing project at the University of Idaho, an All Season Vehicle (ASV) RC 30 has been modified for use as a low impact skidding device. Several skidding methods are being evaluated including the use of log chains, tongs, skidding arch, and a modified tractor winch. Both uphill and downhill operations are being evaluated for site impacts, productivity, maneuverability, and machine reliability. Evaluations consisted of elemental time studies, quantitative and qualitative observations, and day-to-day operation of the ASV RC 30. The skid steer qualities of this machine have allowed it to operate with minimal disturbance to the residual stand. Our observations found that the ASV was underpowered for some skidding applications, but the machine was still an overall effective skidding device for most situations. Preliminary data shows that the ASV is an effective multiple use tool for small wood management.
