Growers state that the finish hand pruning takes only 25% of the time versus total hand pruning costs. The Prepruner cuts the long canes small enough that they fall through the wire which is an aid in clean-up. The Prepruner features a dual system for opening and closing of the cutting heads, unique magnetic sensors and manual hand lever. These front mounted Prepruners for vertical trellis vine grapes are low maintenance and high production giving the Collard units high marks with several leading California growers.
