A system for monitoring the operational status of ground-engaging tools of an agricultural implement. The system includes a frame and an assembly including an attachment structure configured to be coupled to the frame and a ground-engaging tool. The ground-engaging tool is pivotably coupled to the attachment structure. The system further includes a shear pin at least partially extending through both the attachment structure and ground-engaging tool to prevent pivoting of the ground-engaging tool about the pivot point when the shear pin is in an operable working condition. Additionally, the system includes an electrical connection through one or more components of the assembly or the shear pin and associated with the shear pin. The system further includes a controller electrically coupled to the electrical connection. The controller is configured to determine a change in the working condition of the shear pin based on an electrical property of the electrical connection.

Planting apparatus includes: (i) a housing that defines: a primary guide; and first and second opposed branch guides extending laterally from the primary guide; (ii) a first runner slidably secured to, and movable along the primary guide; (iii) a second runner securable to, and movable along a first branch guide; and (iv) a third runner securable to, and movable along a second branch guide. The first, second and third runners are configured such that: the second runner is receivable from the first branch guide on to the first runner; and the third runner is receivable from the second branch guide on to the first runner. Drive means move: (i) the second runner along the first branch guide and on to the first runner; (ii) the third runner along the second branch guide and on to the first runner; and (iii) the first runner, together with either of the second or third runners received thereon, along the primary guide.

The invention relates to a plough module (1) with plough-following stabilisation for mounting on a base frame of a plough device, comprising a rotatable first cutting element designed as a hollow-disc cutting plate. A lateral region (122) of a soil ridge can be cut away by moving the plough module (1) on the ground along a ploughing direction (110). The plough module (1) comprises a second plat cutting element (105) with a second cutting edge (106), wherein a base region (121) of the soil ridge can be cut away by moving the plough module (1) on the ground. The plough module (1) is designed as a fully assembled unit, in which the second cutting element, designed as a fixed cutting blade (6), follows the first cutting element (102) in the ploughing direction (110). The cutting blade (6) is angled backwards relative to the working angle, achieving a dynamic balance of forces between the first cutting element (102) and the cutting blade (6) for plough-following stabilisation. A contact plate (8) is provided on the cutting blade (6), which is supported on a furrow wall (121) such that a stabilising effect follows the plough.

The present invention relates generally to agricultural tillage equipment and, more specifically, to a vertical tillage sweep providing low surface disturbance. The sweep comprises a wing structure with a downward and generally vertical fin, and having specific wear coating placed on the various wear surfaces.

A method for ploughing a ground (120) using a plough device (100). A rotatable first plate-like cutting element (102) having a circumferential first cutting edge (103) is arranged on a support structure (101) and is designed such that when the support structure (101) is moved on the ground (120) along a ploughing direction (110), a side region (202) of a soil ridge (201) of the ground (120) is being cut by means of a first cutting region (104) of the first cutting edge (103). A second preferably disc-shaped cutting element (105) having a second cutting edge (106) is arranged on the support structure (101) and is designed such that when the support structure (101) is moved on the ground (120) along a ploughing direction (110), a base region (203) of a soil ridge (201) of the ground (120) is being cut by means of a second cutting region (118) of the second cutting edge (106), wherein the second cutting element (105) is arranged relative to the first cutting element (102) in the ploughing direction (110) such that the second cutting region (118) is arranged before the first cutting region (104) in the ploughing direction (110).

A tillage apparatus for selective primary tillage and seed bed preparation makes use of a selectively moveable primary tillage shank to provide seasonal, in-field and/or on-the-fly flexibility of tillage operation. The tillage apparatus has a cultivator frame, at least one secondary tillage tool mounted on the frame and a primary tillage shank mounted on the frame, the primary tillage shank selectively moveable between a lowered soil engaging position and a raised disengaged position. In a method of tilling or preparing a seed bed, the tillage apparatus is dragged around a field with the at least one secondary tillage tool engaged with the field when secondary tillage of the field is desired, and the selectively moveable primary tillage shank lowered to be engaged with the field when the field is in need of primary tillage or raised to be disengaged from the field when primary tillage is not desired.
