Abstract

This report describes the operations and costs of existing and alternative mechanized lettuce harvesting systems. For mechanization, the immediate prospect is to substitute a harvest machine for the workers who select, cut, and trim the lettuce. Mechanizing the packing and wrapping operations is also possible. Analysis of the cost data indicates that the existing hand-cut, pack-in-the-field system is efficient compared with previous hand-cut methods and is slightly higher in cost compared with machine-cut systems. A ranking of harvest costs places the hand-cut system highest, followed by machine systems involving packing either on the machine or at a shed. Output per worker was increased from nearly 15 to 20 cartons per man-hour by replacing hand selecting and cutting with packing on the machine.
