Time Studies of Hand and Power Pruning Crop Trees in Plantations
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.
