What Is Agriculture Without Mechanization?

I scored a $30 gas powered mini tiller off of Craigslist. Imagine a little 40cc two stroke roto-tiller. The husband wrote up the ad to seem that it didn't work, but when I picked it up, the wife explained that she just didn't like to pull start it anymore, because she has bursitis. I was fully prepared to try and fix it, but the freakin' thing works perfectly, so I used it for an hour today, clearing the weeds under the cherry tree and tearing up bare spots in the lawn. There were some kind of stinging nettle weeds under the cherry tree that are tricky to handle, but with this new machine I was able to just dig that whole area up post haste.
