I believe this is an early 90's model disc. We bought this disc in '94 or '95, we have been strip till since '08 and no longer need this disc. It is 35'9" cutting width. Weighs 600 lbs. per cutting ft. This is a primary tillage disc not a finishing disc. We have the two recap air plane tires for the center section. Please contact me with any questions. Thanks for looking.
