Beckley, Bob . 2000. Ripper Retrofit for the Sweco 480 Trail Dozer. 0023 2310. Missoula, MT: U.S. Department of Agriculture, Forest Service, Missoula Technology and Development Center. 1 p.

Describes modifications to the ripper system for the Sweco 480 Trail Dozer. When the operator backs the dozer without lifting the ripper system, slots that individual rippers fit into become elongated, allowing the rippers to fall out. Modifications to repair this problem and prevent future problems require welding and take about 2 hours. Newer versions of the Sweco 480 Trail Dozer ripper system include this modification.
