Abstract: A spindle assembly for a cotton harvester. The spindle assembly includes an elongated nut having a first end with a threaded portion configured for receipt by the spindle bar. The elongated nut also has a second end, opposite the first end, with a tool receiving portion configured to be received by a tool to tighten the threaded portion of the first end into the spindle bar. The elongated nut further has an aperture extending through the elongated nut from the first end to the second end. The spindle assembly also includes a cotton harvester spindle having a bearing portion rotatably supported by the aperture of the elongated nut and a picking end projecting outwardly from the second end of the elongated nut. The elongated nut is hard coat anodized to improve wear resistance.

Abstract: A picker bar includes spindles which are nonaligned in the vertical direction to define two or more offset sets of spindles on the bar and increase the number of spindles per unit length of the spindle bar. A spindle assembly includes a support carrying two spindles driven from a picker bar drive shaft by a single drive gear. Driven spindle gears are spaced on opposite sides of the shaft axis to facilitate close spacing of the spindles. A doffer column includes doffer pads of differing diameters to optimize doffing of the offset sets of spindles.

Abstract: A coupling assembly for releasably securing an implement to a work vehicle. The coupling system includes top wedges which are engaged in wedge-shaped sockets, and tapered lower hooks that apply a continuous force to a pin or cylindrical rod which operates to tightly engage the wedges in the wedge-shaped sockets, thereby preventing movement and resultant wear between the engaging portions of the coupling assembly and having the capability of handling heavy, high load inducing attachments as well as existing attachments.
