Both of my axles were replaced for $234 outside of the warranty period. The first one, I paid for the part and Exmark paid the labor. The 2nd one, which happened weeks after the first one, I informed my dealer to let Exmark know that I wasn't paying a single dime. And I didn't. This was the fall of 2014 on a 2012 model ( I would not buy a used model).
It is my understanding that this issue has been resolved. There was certainly a tensile strength issue within these axles. After a certain amount of time and stress, they would break (and why there was a service bulletin by Toro). Supposedly, the higher strength axle should not be a problem. I am looking for evidence otherwise, as you can see by my last question in this thread. I have not found anyone with a broken axle AFTER a replacement thus far. We shall see. My fingers are crossed as you can imagine! I ran it last fall and this spring without a problem.
The Exmark/Toro stand ons are not without faults. They are somewhat high maintenance I suppose. I hear of chain and belt issues. I have had NONE. The original belts and chains are still in place! I adjust and lube the chains with the Napa chain spray foam once a week. This takes maybe 20 minutes. I never turn with the tines in the ground (this is what I believe to be almost everyones chain issues). Why would anyone think it is ok to turn with tines buried 3" in the ground?
lawn king, you are still a smart man to not buy new model machines! I don't disagree with you. I was too anxious to own the most productive aerator on the market. And I DO NOT regret it. Even with it's issues, until this new Ryan, it has still been the most productive aerator on the market. It pays for itself over and over annually. For an aerator with a zero fatigue factor, I would buy it again, same machine, with it's faults today.
It will be interesting to watch the Exmark/Toro/Ryan/whoever else joins the party competition. Competition is good for US! I am surprised to see Ryans price tag though. Not sure I'd spend a couple grand more it than for the competitors.
