Some local home improvement stores that offer stump grinders to homeowners include Loweâs, Home Depot and Menardâs. There are also manufacturers you can rent stump grinders from like SunBelt, who averages their prices at around $70 to $300 a day by the size of stump grinder -- small, medium and large.
As to the size of the grinder for a rental I would seek the largest I could find, a 252 tackling 100 stumps like pictured looks like more than a one day job to me. As for sinking later on, be sure to grind the stumps out completely and this will be avoided.
