Update on my frozen bolt problem. Tried 3 things. #1 was to use a jack against my breaker bar. Nope. #2 Tried heating and removing. Nope. #3 Tried long pipe over beaker bar, wedging against concrete wall and using the torque from the mower itself. Nope. --- Have come to realization that I need to cut it off. Bought a couple metal cutting wheels for angle grinder. Parts on order. Hopefully I will find time to do this this weekend. Pretty busy though. Will keep everyone informed on progress. Thank you all for your comments and suggestions. It is very much appreciated.
