I heard rumors that lettuce harvestors have already been designed and are waiting for the correct political moment to be introduced.
When you think of the vegetable row crops that are now harvested by mechanical harvestors, I can't think why lettuce would be a problem. Onions, potatoes, asparagus, broccoli, corn, tomatoes, sugar beets, peppers, grapes, all the seed crops, peanuts, tobacco, cotton, and a bunch more are now under mechanical harvesting.
The Legacy 2480 brings a higher level of reliability, efficiency and productivity to vegetable harvesting.
The machinery angle makes sense, and it must make sense to the big Agri-business. Let's just say they all go mechanised and won't need the cheap labor in a few years. Then what? What happens to all those "guest workers" then? There is no good ending to this mess, I think we've waited too long.
