The last time the blades were changed, it was done by my Kubota dealer. I don't know what they used to tighten them but they were really tight. After the M12 I tried a 16" breaker bar. nothing. Then I put a 19" cheater bar on the breaker bar and I was pulling so hard I thought the breaker bar was about to snap. So I thought about heating them up but I wasn't sure if there are any seals or such in the spindles that could be damaged. So off I go to NAPA and I get a M18 1/2" drive. That bad boy had those bolts out in no time. I thought I would have to charge the battery first but it had at least some charge from the factory so I figured I'd give it a try and it worked great.
