Describes the results of an equipment demonstration July 27, 1999, at the Targhee National Forest's Island Park Ranger District in Idaho. Several small machines were operated to demonstrate their utility in fuels reduction and in thinning small-diameter stems. The tasks included precommercial thinning and shredding, grinding slash piles, shearing and skidding, and processing at the log landing. The machines demonstrated included a Ford Model 276 Versatile tractor with a Royer Woodsman 5-foot-wide horizontal drum shredder, an ASV HD-4520 Posi-Track with a Dymax forestry tree shear, and a Kubota KH-191 excavator with Hahn HSG-140 single-grip harvester.
