Abstract: Metering devices for an agricultural implement apply a field input, for example, pneumatically delivered granular product including seed or fertilizer or sprayed liquid product including fertilizer and the like, to an agricultural field. In the applying of the field input, the rate of application of the dispensers of one section of the implement can be collectively varied in relation to the rate of application of the dispensers of a different section of the implement frame.

Abstract: Metering devices for an agricultural implement are present for applying a field input, for example, pneumatically delivered granular product including seed or fertilizer or sprayed liquid product including fertilizer and the like, to an agricultural field. In the applying of the field input, the rate of application of the dispensers of one section of the implement can be collectively varied in relation to the rate of application of the dispensers of a different section of the implement frame.

Abstract: A non-ground-contacting boom height control system for a vehicle comprising a frame supported for rolling movement along the ground; an operator cab for supporting an operator of the vehicle therein; a pair of boom structures extending laterally outward from opposing sides of the frame for pivotal movement up and down relative to the frame; a lift cylinder coupled between each boom structure and the frame for lifting the boom structures, each lift cylinder including a lifting circuit for lifting the boom when receiving hydraulic fluid under pressure from a conventional valve control and a lowering circuit for lowering the boom when receiving hydraulic fluid under pressure from a conventional valve control, and a conventional hydraulic circuit including a reservoir and a pump for supplying the hydraulic fluid under pressure from the reservoir to the lift cylinders.
