Not sure about the best way here. Bs had brake bands. Probably take off everything so you can get to it and start prying the band away from the drum. I don't think it will be easy but if you stick with it you will get it. Maybe if you get the brake band anchor pin out you can rotate the drum and free the band up as it comes around. I don't know about this though but I would try it. Also, get manuals. Owners and Repair.

Thanks for the info. I have a manual on order for it but I am anxious to get started on it. I took off that cover plate above the brake housing but I still can't see how the mechanism works. If I lube it real well and clean out all the dirt, put it in neutral and drag it around backwards do you think it will do me any good? I will probably have to take the whole thing apart but I am trying to avoid it if I can. The tractor seems to be remarkably intact so I'm more anxious to get the motor running rather than having to hassle with a stuck wheel. Thanks for the advice and keep it coming if you have any suggestions regarding any aspect of this restoration.

Thanks for the help with the stuck rear wheel. I finally got it free through a combination of wd40 and that "pb rust inhibitor" product. Next I plan to drain all the hydraulic fluid and replace all the lines. Any suggestions on what brand etc. of hydraulic fluid should go in it. I live near a major city (Salt Lake) so I probably have access to most types of stores. But is it better
to buy it mail-order through specialty dealers?
Thanks again for the assist.

Well it can't hurt dragging it around for a while. Once while helping my brother get a farmall BN he had the same thing, one wheel stuck. We were dragging it the 100 to 150 ft out to where it could be loaded onto a trailer and just before we would have had to drag it onto the trailer the wheel freeded up and it rolled onto the trailer. The engine didn't free up though, and he is still working on it along with several other projects. If it doesn't work after a few tries it probably won't though, at least for that day. Good luck and keep us up to date. We learn from the problems others solve too.
