I bought a new Toro Proline 48" Walkbehind. Mowed about 2 hours with it but was concerned becuase of vibration. Found all three spindles appear to be bent where the pully is attached on top. When you spin the pulleys you see a very extreme wobble of the top spindle. I noticed when I looked under mower that the grease was coming out of the middle spindle bottom bearing and it was grinding when I would spin it. Brought it to Toro Service Center for warranty repair but they would only replace the bearing not the spindle because they were saying it is normal for it to wobble. Anyone know how much wobble is acceptable and is this normal. I had a hard time understanding why they would take the spindle apart to put new bearing but not replace the shaft which must be bent. The one the bearings went out on was the worse wobble of all three. The service center told me not to bring it back to them and seek service elsewhere because I questioned why they wouldn't replace the bent spindle and called them incompetent.
