    2009 Lazer Z 60" ZTurn, less than 300 hours, light commercial use-this is the second one. Axle from drive motor. No curbs.

    What do you think?

    Manufacturer defect. It could have had a micro crack or fracture. My bet would be that heat cycles from normal use caused the defect to show it self.

    The right side axle went at 175 hours. New pump and drive motor installed by dealer, covered under warranty. Now the left side has done the same thing, about 100 hours later. They said they normally don't even cover 1 of these repairs; they call it abuse. I'm the only driver and my last machine was 13 years old and never had anything like this. So I don't think I'm abusing it-I'm just mowing. But needless to say, they don't want to cover this latest one...

    Those are heavy machines, If you ever skid on the pavement this is likly to happen. I have guys that go through those axles like crazy and other guys that never have a problem. So if you went through 2 I would say abuse.
    It also could be possible that it happened before you bought it. Last year I was driving by the local Toro dealer and saw them popping wheelies with a brand new Toro 60inch ztr.

    Also, Have your dealer call exmark and see about getting a used shaft. Harold in the warranty department saves the shafts out of warranty returned wheel motors. They are perfectly good still. Just go one a couple weeks ago.

    Going over bumpy lawns at full speed?

    All lawns around here are bumpy. Certainly at times I've gone fast on that type of lawn. Again, same as with my last machine which ran great for 13 years. I hate to think that constitutes abuse..

    Yes but your old mower was slower and lighter. Speed+Wieght+Running to the max=bad things

    Are you the only one that has driven this mower? A manufacturer would tell you someone is backing this mower down on pavement, then slamming forward attempting to pull the front wheels.

    I'm 100% sure that has never happened. I'm the only driver.

    The manufacturer did say that it looks like it was being turned very quickly on hills, or curb hopped. Neither of those are true. Then they said the bagger and weight kit probably contributed-it is their bag and weight kit though...so now they say I have to "baby it"..
