No mushrooms been used. But yes only 12 teeth this pasted year. Keep in mind that they may not be perfectly round and they are at the point they will be replaced this month. Full time is relative. I grind a avg of 10 to 15 a week.
As far as the 112" stump if my son was not grinding on it to learn I would have had it done faster. It was cut down around three months before I could get on it because of rain and there backyard held water. And no I donot have the Autosweep on. Shut it down years back. Its to slow. I do all the work on my machines.
The SC252 is a good machine if you take care of it and it will take care of you. And yes, I get longer life with just 4 teeth on the machine. My rule is, It only as hard as you make it. I like it easy.
