An agricultural tillage implement, comprising at least one section including a plurality of attachment bars; and a plurality of indexed seedbed tillage arrangements distributed on the at least one section, each indexed seedbed tillage arrangement including a first horizontal tillage apparatus coupled to a first attachment bar; a second horizontal tillage apparatus coupled to a second attachment bar and offset in the travel direction from the first horizontal tillage apparatus; and a vertical tillage apparatus coupled to a third bar of the plurality of bars and offset in the travel direction from the first and second horizontal tillage apparatuses, positioned such that it processes soil not disturbed by the first and second horizontal tillage apparatuses.

An agricultural implement includes a frame having a longitudinal axis and laterally opposed sides and motive supports mounted to and supporting the frame. The agricultural implement further includes a first wing carried by the frame and at least one second wing, in which each second wing is pivotably connected to the first wing. The agricultural implement also includes an elevator mechanism configured to raise and lower the first wing and the second wing. Each second wing is connected to the first wing by a wing pivot assembly that includes a skewed hinge pivotably connecting one of the second wings to the first wing. The wing pivot assembly allows each second wing to pivot with respect to the first wing between an operating position and a transport position, in which the skewed hinge defines a first pivot axis oriented at an acute angle with respect to the longitudinal axis.

A remotely positionable stabilizer wheel arrangement for a towable agricultural implement utilizes a control unit that receives an input signal indicative of a desired position of the stabilizer wheel, and/or a desired depth of penetration of tillage tools operatively attached to the front and rear of the implement frame, to automatically control a hydraulic positioning cylinder of the remotely positionable stabilizer wheel arrangement to position and hold the stabilizer wheel at the desired position of the stabilizer wheel, by controlling pressure in the hydraulic cylinder to hold the stabilizer wheel at a target position determined from the desired position input signal.

An apparatus, which may be a tillage apparatus, is disclosed that may have a flexible frame. The frame may be made from open members. The frame may support ground engagers and may be supported on wheel assemblies. The ground engagers may be connected to a spring trip mechanism. The ground engagers may be mounted to open members of the frame with a clamping style mechanism. The clamp mechanism may include wedge devices. The frame may be lowered and raised relative to wheels of the wheel assemblies with a lift mechanism. One row of ground engagers may be raised or lowered relative to the frame independent of another row of ground engagers. An anti-skid or skew control system may be employed in association with the independent height adjustment of one row of ground engagers. A system may be provided to maintain and control the height of a tow hitch forming part of the apparatus.

A soil opener comprises first and second soil-cutting members. The first member has a first soil-engaging surface inclined at a first angle perpendicular to the soil surface when viewed along a travel direction, the first angle being greater than zero, and at a second angle to the travel direction when viewed along a perpendicular, the second angle being greater than zero. The second member comprises a rotating disc and has a second soil-engaging surface that faces away from, and in a substantially opposite direction to, the first soil-engaging surface, the second soil-engaging surface being inclined at a third angle perpendicular when viewed along the travel direction, the third angle being greater than zero and in the same sense as the first angle.

A sensor system for determining soil characteristics is disclosed herein. The sensor system includes a ground engaging device for coupling to an agricultural implement. The ground engaging device includes at least one disc member having an aperture and an elongate shaft extending through the aperture. A first sensor unit is arranged on a sensing surface of the disc member and is configured to measure forces acting on the disc member. A second sensor unit is arranged on the elongate shaft and is configured to measure forces acting on the shaft. A processor is communicatively coupled to each of the first and second sensor units. The processor is configured to generate an output signal indicative of a soil characteristic based on the forces measured.
