Abstract
A study of nine commercial vineyard pruning operations covering some 3600 acres in four counties has shown that the manpower requirement for pruning was reduced an average of 30% during the 1965–66 season, when the use of pneumatic pruning machines was compared with conventional hand-pruning methods. A dollar savings averaging about 15% of the cost of hand pruning was also achieved, even after an original investment in pruning equipment of $12.65 per acre.
