Hi, I'm new to the forum and new to tractors. I have a L175 with one very rusted rear wheel. It has AG tires. From my research,finding a replacement wheel is going to be difficult. I know people repair rusty wheels. My thoughts are to purchase a new blank 7"x24" outer rim then remove the original center disc by grinding away the welds to free it from the outer rim then weld it to the new outer rim. Would this be the best way to make the repair? Your thoughts and advice are welcome,thanks.
