I belong to about half a dozen different JD forums, though this is by far my favorite. Here when you ask a question, you get good solid answers, often accompanied by illustrations. Other places seem to have a lot of opinions rather than solid technical advice.
But there is one thing every site seems to have in common and I find it kind of humorous, whenever someone posts about how many bottoms a particular tractor can pull, someone always pops up with a version of, "Oh, you'd never do that in our soil!" This perverse pride in having hard to till ground has always struck me as pretty funny. I don't know if it is a regional thing or the pride some people take in having to work harder to make a living off their land. Growing up, we farmed some pretty rocky ground, enough so, that the tractor pulling the rock picker during spring work had more engine hours on it than either the tractor pulling the cultivator or the one pulling the press drill. As "the kid" I got to spend most of my time on the rock picker. We prepared the seed bed by cultivating it twice before planting and because each pass with cultivator dug up more rocks, you had to go over it with the rock picker each time. It wasn't just stones the size of footballs or watermelons, we had a lot of boulders to contend with each year too. In a rock pile not far from the farmyard, there was a huge boulder that had been split in half by lightning after being hauled there, when it was whole, it was over 5' in diameter. My grandfather dug that one out by hand and hauled it with horses, I can't begin to think of the effort that took. Sorry, I'm digressing a bit here, thinking about my youth on the farm, but my point is this, the people with rocky ground like ours considered it a curse, not a blessing, and took no pride in it at all. So, I guess that is why I tend to shake my head and laugh when some people seem to take delight in their hard to plow soil.
