Abstract: The Objectives of this project are: 1. Development of an electric type leaf vegetable harvester to replace gasoline engine for greenhouses, both of harvesting mechanism and travelling mechanism are
driven by electricity; 2. Improvement of a leaf vegetable harvester which developed last year for operating in open vegetable fields. The expected results of this project are: 1. The bottleneck of vegetable production in greenhouses is the harvesting. The introduction of suitable harvesters for vegetables can reduce the labors needed tremendously. This will also promote the farmers to extend their business. Leaf harvester may be harvested leaf vegetables before mature with high quality and no need for re-processing old leaves. These performances are good for industrial applications. Greenhouse industry and farmers will be relatively increased willingness to purchase. Therefore, those machines will have a high demand for the market, and therefore have a very high demand and excellent marketability; 2. Similarly, the bottleneck of vegetable production in open fields is the
harvesting. The improvement of harvester for vegetables can reduce the labors needed. This will also promote the farmers to extend their business. Field vegetable cultivation industry and farmers will be relatively increased willingness to purchase. Therefore, those machines have a high demand for the market.
