Re: torquing wheel bolts
Fredoroberts, I guess I'm bad about not covering everything in one shot /w3tcompact/icons/frown.gif but some other points you might consider:
1. You say you don't have a manual and don't know what the target torque for wheel bolts should be. Well, wen said it's 208 ft.lbs. on his bigger tractor, and my owner's manual for the B2710 says 57 to 67 on the front (shop manual says 57.1 to 66.5) and 145 to 166 on the rear (shop manual says 80 to 93). So, it ain't an exact science, and I wouldn't think your B2150 would need to be tighter than the B2710.
2. You say you bought an impact wrench that puts out 600 ft.lbs. in reverse and it had to work hard to get them off. It should have spun them off quite easily. So . . ., I'd consider whether they had rusted and that made them hard to take off, or whether someone in the past simply put them on tighter than they needed to be. Unless of course, you didn't have adequate air pressure (90 psi) or volume, or you have a defective impact wrench (not too likely).
In my humble opinion, it's more important to tighten all of them the same than it is to get an exact degree of tightness. And the way I do that is to run'em all down barely snug, then tighten one, move directly to one on the opposite side (180 degrees if you have an even number of lug bolts, or as close to it as possible if an odd number), tighten that one, and work back and forth that way.
