Thank you for your replies. This afternoon i called our local New Holland/Kubota dealership and i talked to one of their mechanics. He was concerned that the diff was not unlocking. He stopped by and checked it out, and all is good. He said what urednecku said. He also said if the diff had been staying locked it would want to go straight and with the wheel turned it would be tearing up turf.
I hope i'm not doing anything wrong, and if so i apologise, but i would like to give a shout out to this dealership. I called this afternoon, one of their mechanics came to the house, checked out my tractor, and would not take a penny. If anybody in western N.C. is looking for a great dealership Blue Ridge Tractor Company is definitely that.
