Abstract: A mobile harvesting system is towable longitudinally by a vehicle along a field. The mobile harvesting system includes a trailer frame having wheels and a tongue configured for coupling to the vehicle. A harvesting frame is elongated and pivotally mounted to the trailer frame for pivoting between a longitudinal orientation and a transversal orientation. The harvesting frame has a plurality of sleigh attachments distributed along its length. A plurality of harvester sleighs are each coupled to a corresponding one of the sleigh attachments at a corresponding transversal position relative to the trailer frame. Each harvester sleigh has a first runner transversally spaced apart from a second runner, the first runner and the second runner both being longitudinally oriented and structurally interconnected by a sleigh frame.

Abstract: A plow blade system is adapted for mounting to a vehicle. The system includes a central blade having two transversally opposite ends and a mount for mounting the blade to the vehicle in a configuration where the central blade is orientable transversally to a longitudinal orientation of movement of the vehicle. The system further includes a lateral blade. The system further includes a hinge pivotally coupling a lateral edge of the lateral blade to one of the opposite ends of the central blade about a pivot axis. The hinge has an upper hinge element and a lower hinge element. The upper hinge element is interspaced from the lower hinge element. The lower hinge element has a multi-axis rotary joint.
