ABSTRACT:
A vehicle and, in particular, a feed cart as used in a barn to feed the livestock, which vehicle or feed cart is distinctively provided with an electric motor, an electric plug in cord supplying electric power to the motor from an electric outlet of the barn, a reel for the cord, and a reel drive assembly rotatively biasing the reel toward winding of the cord thereon to thus maintain the cord taut and to prevent entanglement and soiling of the cord, independently of displacement of the latter. The reel drive assembly includes a lever, with a friction drive wheel and an idler pulley rotatively mounted on the lever, and a spring biasing the lever, whereby the cord in operative engagement with the idler pulley, upon reaching a predetermined tension, causes pivoting of the lever and disengagement of the friction drive wheel from the reel and when the tautness of the cord is released, the spring acts on the lever to drivingly engage the friction drive wheel with the reel to windingly bias the cord to restore tautness thereof.
