A tillage implement has a main frame towed in a forward working direction and toolbar assemblies supported on the main frame. Each assembly has an elongate toolbar member transverse to the forward working direction with tillage units spaced along the toolbar member for working the ground. A pivot supports each toolbar at an intermediate location on the toolbar for angular adjustment about an upright axis relative to the main frame. Followers at opposing ends of each toolbar member are received in respective guides at fixed locations on the main frame such that the followers are slidable within the guides in the forward working direction while restricting rotation of the toolbar member about a longitudinal axis of the toolbar member relative to the main frame. Angular position of each toolbar is controlled by an actuator with an attached mechanical indicator that can be read by an operator.

An agricultural implement wear monitoring system that monitors a first component of an agricultural implement. A sensor detects and emits a signal indicative of a first geometric dimension of the first component and/or a second geometric dimension of the first component relative to a second component. A controller couples to the sensor. The controller monitors the first geometric dimension and/or the second geometric dimension, and in response to a detected change in the first geometric dimension and/or the second geometric dimension determines a remaining service life of the first component.

A ground engaging agricultural blade, coulter, or disc having a central opening adapted to be attached to an implement for rotation about a substantially horizontal axis of rotation; the coulter or disc have an outer periphery; and plurality of step plane notches disposed in the outer periphery. The blade can be used with a hub disposed around the central opening or a spacer spool on a shaft extending through the central openings of adjacent blades, the spacer spools extending radially outwardly by a distance.

A concentrated high-speed rigid hub allows for heavier planters, high-speed planting and seeding devices in multiple and multiple challenging applications such as no-till, high cation exchange capacity (CEC) soils, compact soils, moist soils, high concentrations of stubble and or Bacillus thuringiensis (Bt) crops, and cover or green crops with massive structured root systems. The hub is made of one of high strength forging steel and medium carbon cast steel, whereby the hub lessons hub flexing, hub bending, cracking and premature failure. The hub comprises rigid, heavy duty deep bosses or gussets which increase structural strength and maximize the strength of attachment points adapted for either bolts or rivets attachment to a blade or object.

A method of manufacturing an agricultural tillage disk blade includes providing a substantially circular-shaped disk body with an outer peripheral edge and a central opening that defines a rotation axis, the outer body being disposed within a first plane. A plurality of waves is formed in a predetermined pattern in the outer peripheral edge of the disk body, and the outer peripheral edge is sharpened to form a plurality of teeth such that at least a portion of the sharpened outer peripheral edge is disposed within a second plane that is parallel to the first plane and substantially perpendicular to the rotation axis. The method also includes machining a plurality of relief portions in each of the plurality of waves at a location radially inward of the plurality of teeth, and heat treating the disk body after the sharpening and machining steps.

A system and method cuts and increases surface area of surface stubble material while contemporaneously mulching, tiling and aerating the soil. A discoidal coulter blade is configured with sharpened areas at the circumference for cutting the surface stubble as well as reducing the downward pressure required for the blade to enter the type and depth of soil desired. The sharpened areas include a first long bevel, a second shorter bevel and an optional opposite counter bevel. The first and second bevels aid in coulter blade lifespan ensuring a self-sharpened blade while the counter-bevel allows mating with a second coulter blade at a sharpened point.

In one aspect, a system for detecting plugging of an agricultural implement may a disc rotatably coupled to a frame member, with the disc configured to rotate relative to soil within a field as the implement is moved across the field. The system may also include a disc scraper coupled to the frame member, with the disc scraper configured to remove the soil from the disc as the disc rotates relative to the soil. Furthermore, the system may include a sensor configured to detect a parameter indicative of an acceleration of the disc scraper relative to frame member. Additionally, a controller of the system may be configured to monitor the acceleration of the disc scraper relative to the frame member based on data received from the sensor. Moreover, the controller may be further configured to determine when the disc is plugged based on the monitored acceleration.
