Abstract: An implement includes a frame, a tower, a manifold, and a retractable mount. The manifold is attached to the tower. The retractable mount attaches the tower and manifold to the frame and is configured to allow the tower and manifold to move between an extended position and a retracted position relative to the frame. A distance between the manifold and the frame is greater in the extended position than in the retracted position.

Abstract: A seeding machine having a plurality of seed meters receiving rotary input from a common input shaft. First and second gearboxes respectively connect the common rotary input to individual seed meters. A flexible drive extends from the gearbox adjacent the common rotary input to the seed meters. Spring clutches, normally connected, are electrically actuated to disengage the drive to the individual seed meters. The clutches may be integrated in the gearbox adjacent the rotary drive or the gear box for the individual seed meters.

Abstract: A level indicator for a disk harrow or the like having a motorized on-the-go leveling adjustment. A small diameter flexible cable is attached to the spring retainer which bears against one end of the coil spring on an adjustable link structure located between pivoting hitch structure and the adjustable ground wheels. The opposite end of the cable is attached to a slide which is free to move vertically in a bracket fixed to the motor mounting bracket. The weight of the slide maintains tension on the cable and as the motor is activated to move the spring retainer relative to the motor mounting bracket, the cable moves the slide vertically to provide an indication of the leveling adjustment. The consistent relationship between the spring retainer and the motor bracket at a given adjustment position provides an easy to read indication even though the entire leveling system may be moving relative to the machine frame.

Abstract: Adjustable link structure for providing on-to-go disk harrow adjustment from the cab of the towing vehicle. The mechanism for automatically maintaining the frame of a disk harrow at a level condition as the frame is raised and lowered relative to the ground includes an adjustable link member with a rotary hydraulic motor utilized to adjust a mechanical screw type mechanism to maintain a set adjustment position independently of continued fluid pressure to the motor.
