The out of town guys who came in after the ice storms would grind stumps for whatever you had in your pocket. Flagged one down one Sunday afternoon, took care of a stump in my back yard for $42. We started at $150. In and out of the yard in about 10 minutes, machine a little bigger than the yellow one above. Guy drove it into the back yard, then moved two little handles up and down while the grinder went back and forth like the stump was made of butter.

Had to clean up the mess myself, but it was a well spent $42.
