I love grinding above ground stumps/rootwads with a sharp (sharp) stump grinder. Little dirt to slow you down, no hidden rocks. I grind the roots first while heavy part of stump holds them. Some break off, near end of grind a liftable size piece of wood is left. From six stumps I would expect a pick-up size load of root ends, broken pieces, and pieces of wood to load up and haul off.
Carbide chain is so slow in a big cut of wood that you want to turn the saw on yourself in a few minutes. Carbide drags on wood and creates sooo much friction.
If you have sprawling roots above ground (or anywhere) that you did want to cut off the Oregon product Instasharp (?) is a consideration. I have 16 inch set up's I keep on one powerhead. Dulls like normal chain but after cutting a couple of roots you put on the sharpening cassette and it is back to sharp in 5 seconds. Cut a couple more roots and repeat. I got 12 to 15 sharpenings on a new chain from completely dull cutting in ground roots. (Always reinstall sharpening cassette in the same direction to use.)
Ooops! Google shows it to be Powerhsarp. Ebay often has good prices on new set ups here in the US. You need a bar as well at first.
