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 pivotably coupled to the attachment structure at a pivot point. 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. Additionally, the system includes a sensor configured to detect a load applied through a pivot member extending through at least one of the frame or assembly at any pivot point between the frame and the ground engaging tool. The system further includes a controller, communicatively coupled to the sensor, configured to determine a change in the working condition of the shear pin based on the detected load applied through the pivot member.

A ground utility robot and implement attachment apparatus having a ground utility robot, at least one implement, at least one solar panel, at least one battery that is chargeable by the at least one solar panel, a power take-off system that is connected to the ground utility robot and to the at least one implement; where the battery powers said ground utility robot and the implement; a safety system that has a computer, a safety program that utilizes a processing logic on the computer, where the safety program initiates precautionary measures that are carried out by the ground utility robot and the power take-off system if an object comes within a predefined distance from the ground utility robot and implement attachment apparatus.

An agricultural implement system includes: a work vehicle with an engine carried by a vehicle chassis and a PTO coupler coupled to the engine; an agricultural implement including a power take-off coupled to the PTO coupler, a feeder configured to feed crop material, a pickup configured to convey crop material to the feeder, and a plug sensor associated with at least one of the feeder or the pickup and configured to output a plug signal; and a control system including a controller coupled to the plug sensor. The controller is configured to: receive the plug signal to determine a plug condition exists; output a PTO decouple signal when the plug condition exists; output a stop signal when the plug condition exists; and output a plug clear signal so the power take-off is recoupled to the PTO coupler and the work vehicle resumes moving when the plug condition no longer exists.

A tractor includes a link mechanism and a power extractor. The link mechanism includes a top link, a right lower link, and a left lower link. A work apparatus is connectable to the link mechanism to move the work apparatus upward and downward. The power extractor is connectable to a power input of the work apparatus to take power from a power source and supply the power to the work apparatus. The power extractor is located at a position lower than a lowest position of the right lower link and a lowest position of the left lower link.

Gearbox device for an agricultural machine comprising a primary shaft, a secondary shaft, at least one intermediate shaft, and a motion transmission element moveable between at least two operating positions in which it sets up intermeshing drive lines between the primary shaft and the secondary shaft with different gear ratios, at least one of the drive lines incorporating the intermediate shaft, the motion transmission element passing through at least one neutral position during its movement between the at least two aforementioned operating positions, wherein the gearbox device comprises a manually-operated pivoting means that makes it possible to make at least one of the primary, secondary, and intermediate shafts pivot around its rotation axis when the motion transmission element is in the neutral position.

A generator unit to be attached to a traveling vehicle that has a prime mover and a PTO shaft to transmit power from the prime mover, includes: a generator; an input shaft having: a first connector portion configured to be connected to the PTO shaft; and a second connector portion configured to be connected to a working device to be connected to the traveling vehicle; a transmitter mechanism to transmit, to the generator, power supplied from the PTO shaft, the power being inputted from the first connector portion to the input shaft; and an attachment frame having: an attachment portion to which the generator, the input shaft, and the transmitter mechanism are attached; and a mounting portion configured to be mounted to the traveling vehicle.
