You are right on. Sometimes its dry as a bone. Just depends on when it gets drained. One field of ours was muddy. The rest was dry. In fact we were burning and disking right behind the combine. Yes we will put anything to the test here. Tractors, planters, sprayers, cotton pickers, and combines just to name a few. Engineers just think that their design is tough until they test it here. One more thing about rice is the high yeilds. Its pretty common to see 200 bu. per acre.
