Thanks very much for the thoughtful replies. Its a great community here

and very helpful for a new tractor owner like me. I did pick up a 26mm socket and breaker bar at a local store since I needed a 1/2 breaker bar anyway. I will grab the 3/4 set in the near future. I used a 4' pipe and with my 270 lbs was able to turn the lugs. I used some PB blaster penetrant to assist. After a few turns it started to loosen, so I used my impact gun to further things along. Unfortunately the bolt just spun in the hub so i guess the threads are stripped

I quit there since my reason for removing the tires was to paint the rims front and back. I painted the outsides and called it a day. I will soak the lugs from hub and try again in the future. I may have to use heat for the assist.
