Ok, getting super ticked off now. Dealer was great, found me a pair of tires that are level. He also snagged a little black grip for the loader pin release off another tractor because mine was missing. Got home, double checked tires and air pressure, mounted on tractor. Still no change. Checked front tires-they are ok. I then rolled bucket down till the right side touched floor. Tried loosening loader frame on right side and put floor jack underneath, raised it till it started moving tractor, then tightened bolts back up-still no change. I then loosened the left side loader frame from tractor frame-bucket dropped level. Bad news is as soon as I tighten any of the mounting bolts, it pulls the bucket back off ground on left side. Calling dealer today or tomorrow to see what can be done. I'm getting close to saying I want my old 1870 back and cancel the deal....
