ABSTRACT:
A ground engaging wheeled trailer includes an elongated chassis having a horizontal deck overlying an upright rolled, hair pin shaped I-beam track including a horizontal section extending the length of the deck, an integral vertical section extending downwardly at the rear of the deck, and an integral, forwardly and upwardly inclined third section. A plurality of cars are mounted for movement on the track by car wheels engaging opposite side recesses within the I-beam track. Each car includes a hinged plate at a radially outboard position on the car. A U-shaped cam follower yoke is fixedly mounted to a spear adjacent the hinged plate and carries cam follower rolls to opposite sides thereof for engaging with respective camming bars to opposite sides of the track third sections. Cam slots formed by spaced camming rails forward of the track third section cause the hinged plates to pivot to a position such that the spears carried thereby are horizontal and generally parallel to the longitudinal axis of the cars. The cars are fixedly coupled to a chain at longitudinally spaced positions over the length of the car corresponding to desired spacing of the impaled round hay bales on the trailer deck.
