Jeff, that's great. I have owned one for just over a year, put only 100 hours on it, but it has not let me down, much. Had two early issues, but the dealer supported me well.
First issue was a parking brake that somehow broke, leaving me stuck on a customer's driveway, blocking it, on a Saturday. I had to make about 10 phone calls before I got satisfaction, but it happened. No long term complaints on that one.
Second was when one of the hydraulic lines broke on one of the tracks. I was not operating, so didn't see if my man ran over a stick that knocked the line, but sort of doubtful given where we were operating (asphalt, mostly clear). Again, called the dealer and got warranty satisfaction. Though it did take some tough-talking, and more than a few phone calls, it was rescued free of charge.
I have stuck this machine on a few stumps however, due to it's very low height (not sure how it compares to other mini skids) - so watch out and really really try to know what you're driving through/over. If you're in a woods setting, try to clear a path and stick to it. Put a cone on stumps near your travel lane.
And keep your tracks tight! I think the number is 9 and 5/16" or so, and it will behoove you greatly to stick to that. Also, KEEP YOUR OWNERS MANUAL IN THE BOX ON THE FRONT OF THE MACHINE, WHERE IT IS REQUIRED TO BE. This is an OSHA regulation (as I understand it), and it came in quite handy for me about two weeks ago.
If you didn't get the required tools for tightening the tracks when you bought the machine, ask me what they are, I'll let you know. Don't have the numbers in front of me right now.
