      abstract = {Felling and skidding operations were monitored while  clearcut harvesting a 12-acre area of a 14-
year old  loblolly pine (Pinus taeda) plantation. The study area  contained 465 trees per acre for
trees 2.0 inches Diameter  at Breast Height (DBH) and larger with a Quadratic Mean  Diameter
(QMD) of 7.26 inches. Two feller-bunchers (tracked  and rubber-tired) and two skidders
(conventional and large  capacity) were paired to create four different harvesting  systems which
were randomly assigned to 3-acre units for  evaluation of production rates and costs. Each system
was  balanced to determine the number of machines needed to  minimize the cost of producing
each ton of wood. Cost from  woods to landing ranged from $1.92/ton to $3.16/ton. The  two
systems that incorporated the large capacity skidder  performed better, and at a lower cost per ton,
than the  systems that used the conventional skidder.},
