Abstract

We developed a practical lettuce harvester with a combination of technical elements to save labor. The use of this harvester with a couple of workers involves almost no bending, and is a very accurate all-round harvester. On our first trial run we attached the harvester to a tractor but we found a problem with mulch-film flexibility caused by the tractor. The harvester was as efficient as manual labor. On the second trial we tested a self-operated harvester. It proved to be the most practical harvester. It cut the lettuce very accurately, was very flexible in the field.
