Query: Doesn't a mower mow grass?

My son has had this mower for 2 years. The wheels fall off all the time, and he CANNOT push it in the grass. It's fine for playing indoors when he was younger, but now that he wants to "help Daddy" outside with the lawn, its a pain! Please consider this when looking to purchase this item.
