Mower deck question. I have an old quietline 44A mower deck that the spindles are nice and tight on. I ran across a 50C mower deck for the 82 series on up. (I think it is much later because the spindles are the new style) Anyway's bearings are shot in the 50C deck and I wanted to convert the deck to the quietline. If I pull all three spindles out of the 44A deck will they go right in place? I know the old style spindles are retained with a carriage bolt, and the new deck does not have any square holes in the plate that goes on top. Anybody done this conversion????
