I have a f935 72" front deck mower. I have been mechanicing for most of my life so this really has stumped me. I can't get the shaft to press out of the hub assy. Do I need to heat up the hub? I don't like that idea as I beleive it will damage the seals. I have already broke one housing trying to press the shaft out. I am pressing on the bolt that holds the blade on. Does anyone have any tips for replacing the bearings in the hub?
