Description

ANNOTATION: A productivity study was performed on a tree length harvesting system thinning a Ponderosa pine stand in Flagstaff, Arizona investigating opportunities to lower the costs of fire hazard reduction treatments in over stocked stands. The harvesting system consisted of a Hydro-Ax 421 E rubber tired feller-buncher with a shear head, a Caterpillar 528 grapple skidder and a Denharco 4400 stroke delimber mounted on a Caterpillar 320C base. Detailed time study was used to gather productivity data for all machines in the harvesting system. This paper presents the results of the study including a description of the stand, study methods and productivity equations for each machine.
