Effect of tire size on skidder productivity
During the spring of 1996 a collaborative effort among Mead Coated Board, the Auburn University School of Forestry, and the Southern Research Station was initiated to evaluate skidder production performance as a function of tire size and soil condition (i.e., wet and dry season). The objective of the study was to determine production and cost differences among 28L-26, 30.5L-32, 67x34.00-25, and 66x43.00-25 tires. The first portion of the study was completed for dry sites, and there proved to be no significant differences in productivities among the tires tested. Wider tires do not hinder productivity under dry conditions. Additional data for the same tires will be collected under wet conditions in order to make comparisons among the tires and between the seasons. The goal is to develop a strategy for optimal tire management.
