as far as cutting time goes, Deere blows by Case in a landslide. I have cut in some very tough conditions: Butte wheat, weedy and a high humid cool day, late into the evening. The Case's didn't leave the yard at all, while I cut all day. You have no idea how valuable that is when you are on the harvest run down south. Time and Time again, JD beats case in tough conditions. Case has a great machine, but it won't keep up when the straw is tough.
