Hit a rock, blade bent and mounting screw broke, sheared the four tabs on adaptor that lock blade in place.
Remove blade, remove plastic housing to get at adaptor. Remove adaptor by loosening the drive belt tension. I was able to slip the belt off between two pulleys to gain the slack needed to remove the adaptor rather than remove a pulley. The blade screw had broken off so that i could grab the piece remaining in the end of the crankshaft, and remove it by hand. Assemble in reverse order. I put low strength loctite on machine threads so screws stay in place.

Bolt holding sleeve and mower blade to crankshaft broke 1/2 way into crankshaft.
Drilled hole into the part of the broken bolt still inside crankshaft, I then heated the bolt that was still inside the crankshaft with a propane soldering torch and used penetrating oil to soak into thread and then used an easy-out to remove the remaining half of the bolt from inside crankshaft.
I then replaced the old parts with the new ones I had purchased from your company
