Jim,
I have a new 4310 exactlly like yours, with the 300 cx loader. I have purchased the 72" front arm-mounted blade, but have not yet picked it up (have not had the time to get the tractor to the dealer 100 miles away and stay with it until the SCV is fitted). I ordered the hydraulic angling kit for mine, but I am not sure whether I want to invest in it yet. Even though I really enjoy my 4310, I am planning to look at the 3000 series when they come out, mainly for curiosity but perhaps for trade if they seem significantly better. My questions are: first, is it a difficult task adjusting the angle of the blade manually, and second, have you heard rumors that the new 3000 series would be outfitted to accept the hydraulic angling kit without adding another SCV? If so, I may not need the whole kit if a trade occurred. Do you or any other forum member know the answer to this, or does your dealer? My dealer is excellent, but does not know and neither did his regional rep. This would potentially keep me from having to order the same kit twice.
