Fortunately my son has only shredded the belt on my lawnmower to this point but know those days are coming.
he did that too, but i dont have a picture of it
if i remember correctly, i had bought that lawnmower back when we lived in lowell, so 16,17 years ago
about 2 years ago the belt started slipping when cutting tall, wet grass so i decided to show it some love and put a brand new belt on it

needless to say, that brand new belt didnt even last 2 years

truth be told, the time we spend fixing the lawnmower (or just teaching him basic maintenance on it will probably turn out to be invaluable
