Operation times in John Deere 1110 e forwarders in regeneration felling

Abstract

We calculated high-power forwarder productivity in regeneration felling with the objective to set long-term work plans. Based on the time studies of the forwarder operator's work operation the operation time consumption was calculated and operation standards for the studied type of forwarder were designed. The standard values were determined based on the volume weight of harvested timber and the forwarding distance. The resulting time consumption required for forwarding 1 m3 of timber, whose mean tree volume is 0.30-0.99 m3·stem-1, and upon forwarding distance of 100-1,000 m ranges from 0.05-0.09 Nh·m-3.
