Trip by old man on a riding lawnmower

This is not an old movie, and I don't think it had any stars in it,
but this old man wanted to visit an old time friend (somewhere in the
south) but did not have a driver's license or car, so he rode his
riding lawnmower for several days across the state to visit this
friend. The movie is about his trip and the people he meets. My
grandmother saw the movie on TV but can't remember the name and would
like to have a copy. Can anyone come up with the name and make an old
lady happy? Thanks. Boondockbob
