Stump Grinder Best

I have a hardwood tree with roots unpleasant high, I have dug around it giving the main roots. I'm thinking?

Rental 20 "chain saw from Home Depot and cutting through the strain and burying the rest. If I clean it very well think that this method work? I explained, I am sure if I saw made through the trunk and roots. Not use a grinder and had to spend about 8 inches to make the ground level, so I think chain saw may be my best bet.

for $ 50 you could get someone to grind down the trunk for you … probably close to what you'll pay chainsaw rental
