We have several large stumps in our yard, maybe 8 or 10. I would say 4 of them are 3 ft across and have heaved the ground up around them. I had a service quote me $500 for all the stumps. We do have some time on our hands off and on and wondered about renting a grinder and doing it ourselves. We have never used one before. How long does it generally take to grind a stump and what benefit would we get from hiring it done vs doing it ourselves? Can we do the same job using the rental equipment?
