Home owner tip: If you want to get rid of a tree stump and you're not in a hurry:

1) drill a bunch of holes in the top of it using a spade bit (3/8" seems to work well enough)

2) fill the holes with powdered milk

3) decorate it in some way so that your doorbell doesn't get worn out by people who like to randomly stop and brag to strangers about how they own a stump grinder 😂
