On one of my new turboforce decks (52"), I had to replace the part which which cradles the blade. It cost about $45 if I can remember right. It's a long cylinder which does right down the middle of the spindle. Anyway, it's not too hard to replace. It can't be if I did it myself. But the problem is WHY I had to replace it. The blade bolt got stuck and I couldn't get it out. It was probably cross-threaded? But how did it get cross threaded when I screw the bolts in BY HAND until they contact the blade, then I torque them down with an electric impact. None-the-less, I could not break this bolt free with a breakerbar and a 6 foot extension. It's been a couple months since that happened, and now my OTHER 2 BLADE BOLTS ARE STUCK. The impact won't take them out. Man am I pissed. Any ideas? Remember, I screw these in by hang until they contact the blade.. so I can't imagine them cross threading..
