For the design of bean harvester, you have consider crop parameter as bean plant height, raw to row distance and depth of root then decide machine parameter like length of cutting blade, plant guide mechanism, threshing cylinder and blower to remove chaff. You have to design each parts of bean harvester and carry out different acting force analysis and power requirement for harvester. I think this information will sufficient to design bean harvester.
