All day if you're a big manly man as I've never seen a rental unit that worked just right or had anything even close to a sharp tooth on it.
One 36" stump, you might come out cheaper to just have a stump service grind it for you. I know I could grind it cheaper than you could rent that crappy Dosko for a day and then you wouldn't even have to break a sweat.
The last one I rented the teeth were very dull, the wheel lock didn't really lock the wheel, and the bar you have to hold to keep the engine running wouldn't keep the engine running unless you had FULL force on the left side.
I told the rental guy that they really need to get those teeth sharpened and he told me that the factory told them that as long as there is carbide on the tooth, it's fine and doesn't need anything. lol
