OK. So I didn't look before I removed the clamps to adjust my rims. I got the one rim all the way out but the side only out about 3". Going to give up on it temporarily and lock it down where it's at. Looks like snow coming in so I'll get to it later. Need to get the blade on the tractor and ready to go. Question is, does the small tab go into the slot on the disc and then the clamp is used as a wedge to lock the rim down? If I put it flat on the disc, there's no way the tab will fit into the slot. Looks like the clamp is angled to wedge against the rim, but just want to make sure. Yea, I know, I should of looked before I jumped into it. Thanks!
