I suppose I am a little ignorant ... I had some dozer work done a while back and the minimum for that was $300. And that made sense to me because it is a big machine, with big parts, diesel is expensive and so is the truck and trailer needed to haul it. I just always was under the impression that a stump grinder was a small machine and low maintenance. Seems like I was incorrect. Thanks for the insight. I am going to keep checking around. Hopefully I won't cause any one to torch any of their machines
