How do you break the bead on a lawn mower tire?
Lay tire flat, place long (and strong) board on sidewall and other end on floor. Walk (or drive with vehicle) up the board until the bead breaks free using the board like a ramp for leverage. Use caution with metal shovels and the like.
How do you take the rear wheel off a MTD riding lawn mower?
Strike the head of the axle bolt with a hammer three times to knock away some of the rust adhering the axle to the rim. Remove the center bolt completely with the socket wrench. Grab the tire on two sides and pull it straight off the axle.
