I have a 2000 54" Bunton hydro walk-behind. When I engage the blades real slow, I can see that one of the spindles doesn't spin in a perfect circle. Must be either bent or the bearings are wearing out. They are greasless spindles, by the way. It's not real bad but enough to notice. Is this something that would affect the cut very much?? It hasn't been cutting that well the past couple weeks.
