After a few holes I got around the shudder problem better. I would push in the clutch, stopping the bit at the bottom of the hole and pull the three point lever all the way back so that the bit came out in one motion. If you try to come out slow is when the shudder is really bad.That way there was only one bang at the top and most of the dirt stayed on the bit. You could move forward and then give the bit a spin and all the dirt came loose. I do really like my tractor and now have 6 hours on it. It is amazing how little fuel they use. Very nimble. Bucket is great. I also have a box scraper that i have not tried yet. There, I think the shudder would be a pain. Going to visit my dealer today and see status of valve and ask about it effecting the hydro as someone said in another post. Thanks, Brian.
