If the tractor was setting for ten years and the battery never maintained, chances are it is dead. There is a checklist in our HOW-TO's forum on what to do when buying a used tractor and also what to do if it has been setting for a long time. Simply putting the battery on a charger does not mean it is good. If the battery has been in it for years, get it to your starter shop to be tested on his bench equipment. If it is bad, replace with a good brand, GRP-1 if 6V, GRP-25 or GRP-35 if 12V. On your sticking brakes, I'd try to back off the adjusting screw first. Access is on the back side of the brake drum thru a window. Original drums had a rubber plug to keep dirt out, but I've seen many that are missing. It is very important too that you invest in the essential owner/operator manuals for your 8N. All 9N/2N/ and 8Ns, up to early 1950, used the front mount distributor, and were all originally 6V/POS GRN systems. After early 1950, FORD went to a side mount distributor, moved it to the RH side of engine from the front, and moved the generator to the RH side. Many N's have been switched over to 12V/NEG GRN systems. It is equally important that you know which setup you have. Either way, it is very important that the electrical system is wired correctly. Simply swapping out the 6V battery with a 12V battery does not make it a 12-volt conversion. Before jumping in head first, get the essential 8N Manuals and read religiously. The I&T F-04 manual, the 39-53 MPC (Master Parts Catalog), and the original 8N Operator's Manual are the most important.
