Case studies of two large Washington vineyards and two smaller Oregon vineyards found that growers who purchase machines to mechanize common tasks will see savings compared to those who rely on hand labor. Mechanized harvesting offers the biggest return, with a profitability result of over $1,200 per acre each year in both a 500-acre vineyard and a 40-acre vineyard. Cane pruning was the only task not suited to mechanization. (Source: Clark Seavert, Oregon State University  Graphic: Jared Johnson/Good Fruit Grower)
