ANNOTATION: In the summer of 2006, the John Deere 1490D slash bundler was brought to Arkansas so that four independent case studies could be conducted where no previous studies on the machine had been conducted in The South. The study sites were a clear cut, a second thinning and a first thinning harvested with conventional equipment. The fourth site was a thinning by cut-to-length equipment. The productivity rate of the machine ranged from 60 to 78 percent. Delays (i.e., saw binding, materials handling, and twine spools collapse) were the main problem of the first three sites and movement was the major nonproductive element at the fourth site. The bundles can be economically produced (based on current markets) and they can be stored for seven to 8 months.
