I am now in the process of working on the deck the Cub Cadet 1600 that was given to me. I have been heating the blade nuts and squirting PB Blaster on them and still cannot get them loose. I am now considering just cutting them loose with a Moto-Tool. I do not want to beat them with a maul because I think the spindles are still ok. Any suggestions? The deck has been repaired by welding which I intend to grind off and patch with heavy sheet metal on both sides.
