Rear wheels support rear ends of the decks, and gauge wheels support front portions of the outer wings. A transport mechanism folds the outer wings upward to a transport position over the inner wings, and then folds the inner wings to a transport position upright from outer edges of the center section. A drive is operative to rotate each blade. Beneficially axes of the blades are oriented alternately forward and rearward across a width of the apparatus. A disclosed drive has a main gear box adapted at an input thereof for attachment to a rotating power source, and slip clutch protected power shafts are connected to outputs of the main gear box to drive the blades.
