Was talking to a friend today that picked up a lazer z for cheap from a customer of his to resell. He was talking about the Exmark spindles needing to be replaced every 100-150 hrs (keep in mind that this guy is a die-hard Skag man and has never owned an Exmark before) He said that this lazer has 550 hrs on it and 2 of the spindles are bad and that another friend of his that has a viking with about 300 hrs on it has to replace all 3 spindles on it. I have the TTHP and the spindles on it seem to in great shape no slop or looseness of any kind and I have 220hrs on it. Is anyone else having these problems or is he being misinformed and a little bias? I know that Exmark uses an automotive bearing manufacturer to make these. And from being an automotive technician for 10+ years I have seen these sealed bearings go out anywhere from 130,000 miles to 220,000 miles on cars. So with this , I just don't see this happening unless these people are just abusing the crap out of them.
