Mechanical harvesting of leafy greens on small farms

Abstract

Over the last century and a half, farming practices have been revolutionized by the advent of mechanical harvesters, but there is a disparity between available agricultural technology and the technology used in the farm equipment that is affordable for operators of small farms. The harvesting practices for salad greens from small farms is just one example of this disconnect. This thesis is a historical and design study of mechanical salad green harvesters for small farms. The designs consist of a frame with power, cutting and collection systems mounted to the frame. Developing an inexpensive salad greens harvester would help small produce farms in one way, but it is only a step toward the overall transition inventors, entrepreneurs and manufacturers need to make toward equipping small farms with the technology that is already in use on large farms. Many consumers have begun deliberately purchasing from local sources. It would be advantageous for farmers and manufacturers alike if agricultural industries began deliberately addressing the demand from small farms.
