Description: There have always been concerns about the impact of timber harvesting with conventional ground-based harvesting equipment on many parts of the forest ecosystem. One of these parts, which is easily measured, is the residual stand. The interest in small tractors (less than 60 horsepower) has increased in recent years because private landowners are concerned that large harvesting equipment may damage their woodlot. Several of these small tractors in the 12- to 60-horsepower range have entered the marketplace. We report on residual stand damage following thinning operations in northern hardwood stands using three small tractors. They include a Holder A-60, Pasquali 993, and Forest Ant. Plots for each tractor were taken after the cut to determine damage to residual trees. Six classes of damage were recorded: bark abrasion, barked skinned, root damage, tree broken off, tree bent over, and felling damage. The following points can be made regarding stand damage caused by the tractors: (1) The Pasquali caused less damage than the other machines; (2) the Forest Ant required greater maneuvering to position it closer to the felled trees; therefore, directional felling was required which resulted in greater felling damage; (3) stand damage from the Holder was mostly due to the larger size and length of the load per trip.
