Time Studies of Hand and Power Pruning Crop Trees in Plantations
Abstract:Pruning studies in the Kellogg Forest in 1956, 1957, and 1960 indicate the time required to prune 150 crop trees per acre of seven coniferous species with a hand saw and ladder, 4-foot pole saw, a hand saw using the "Tarzan" method, 12-foot pole saw, and an electric pruning saw. For pruning large areas, or for operations conducted over sufficient years to depreciate the equipment, investment in a power pruner appears justified.
