Abstract
An agricultural system includes a tillage implement with a frame, a shank mount coupled to or integrally formed with the frame, a rotary sensor coupled to the shank mount, and a shank coupled to a bracket via a first fastener. The tillage implement also includes a rod assembly with a first end portion coupled to the bracket via a shear bolt that is configured to shear upon contact by the shank and a second end portion coupled to a rotary shaft of the rotary sensor.
Claims20
An agricultural system, comprising:
- a tillage implement, comprising:
- a frame;
- a shank mount coupled to or integrally formed with the frame;
- a rotary sensor coupled to the shank mount;
- a shank coupled to a bracket via a first fastener;
- and
- a rod assembly comprising a first end portion coupled to the bracket via a shear bolt that is configured to shear upon contact by the shank and a second end portion coupled to a rotary shaft of the rotary sensor, wherein the rod assembly comprises a rod that extends from a first end to a second end, and the first end is coupled to the bracket via the shear bolt and the second end is coupled to the shank mount via a second fastener.

A tillage implement, comprising:
- a frame;
- a shank mount coupled to or integrally formed with the frame;
- a shank coupled to a bracket via a first fastener;
- and
- a sensor assembly, comprising:
- a rotary sensor coupled to the shank mount;
- and
- a rod assembly coupled to the bracket via a shear bolt and coupled to the rotary sensor, wherein the first fastener in an intact configuration enables the shank to rotate relative to the bracket without contact between the shank and the shear bolt during tillage operations, and the first fastener in a failed configuration causes the shank to contact and shear the shear bolt during the tillage operations.
5 more elements
A method of operating an agricultural system, the method comprising:
- rotating, via a first fastener that couples a shank to a bracket, the shank relative to the bracket as the shank engages soil in a field during tillage operations;
- shearing, with the shank and upon failure of the first fastener, a shear bolt that couples a rod assembly to a bracket;
- rotating, via rotation of a rod of the rod assembly due to shearing of the shear bolt, a rotary shaft of a rotary sensor;
- and
- providing, via a display device, an output indicative of an occurrence of shank displacement in response to the rotating of the rotary shaft of the rotary sensor.
