No difference. The cost could be a bit less from a box store.
Home Depot does have a repair service that repairs lawn mowers. You drop off the mower, they fix it and you pick it up at your convenience.
According to Home Depot "Riding Mowers"
My first stop would be at your local John Deere dealer. Not a Home Depot or a Lowe's but at the actual place that devotes its time and efforts to you the customer and your satisfaction with your lawn mower.

Actually, I work for the Home Depot and I was recently told that we do at certain dealerships. If you work with the Home Depot, just ask the dealer, it wouldn't hurt to try. :) I'm not sure if there is a list of dealerships or not, but when buying a car, just ask them. Most of the time there is.
