I have seen the big Harvesters that run over the Corn, and a built in conveyer belt drops the corn into a bin on the back. Being a home gardner myslef, I know that most Tomatoes produce more than one batch of fruit per plant. That would be counter productive to kill the plant after one harvest, in my opinion, which is agreeable to many I am sure. I hope it gets settled where it is both good for the Farmer, and the Consumer. You appear to be a well rounded worker 4th Horseman. I think it was an H-1 B visa that allowed immigrants to come as temps to work, but even that led to illegal immigration when the workers would run away into "The Shadows".
