I thought it said "A Suede Lawnmower, Pulled by Crows".
How do you get crows to do that? They could grip the suede, I suppose. Big crows, too -- probably a hundred. That damn lawnmower could FLY. It would be a FLYING CROW PROPELLED SUEDE LAWNMOWER.
Then I see it is "A Selfmade Lawnmower, Pulled by Cows".
Which is good, too. But you won't be flying with that one.
