Kubmech,
Thank you for the explanation. I've wondered about the 4 position, and I didn't think it had much application, as I too thought it would give me a faster dump that I didn't need. Now that I actually understand it, I can see why it's so important. I sure wish my dealer had mentioned it or at least given me the option. I have the 3 position and can see down the road that i might be spending the cash for a 4 if i want that front blade....
