The John Deere 1 Series Round Baler lineup includes the 451E, 451M, 451R, 461M, 461R, 551M, 561M and 561R. The "E" model designates the baler is equipped with a regular pickup; the "M" denotes the baler is equipped with the MegaWide™ Plus pickup, and the "R" model shows the round baler is equipped with the High-Capacity or the High-Capacity and Precutting feeding system.

Net-Lift Assist, Net Lighting and a Preservative System are options available for the 1 Series. With Net-Lift Assist there is a 90% reduction in lifting effort as the connecting linkage attaches to the netwrap handles and the netwrap roll is moved into position. Net Lighting illuminates the netwrap and wrapping components, making it easy to reload the baler in low-light conditions. The Preservative System for the 1 Series utilizes a tank, sensors, controller and distribution system to ensure the right amount of preservative is applied to each bale.
