A walk-behind tractor has an increased ground clearance to define a plant receiving space that has a greater height than a conventional walk-behind tractor having a straight axle. The walk-behind tractor has trailing drop arms from a frame that carry wheel axles that result in an elevated height of a driveshaft. The elevated driveshaft increases the ground clearance for taller plants to pass therebeneath during operation of the walk-behind tractor which would otherwise be too tall to pass below a conventional straight axle walk-behind tractor.

An apparatus for efficient targeting or removal of weeds or other plants. The apparatus may include a vehicle having a frame, a motor and a plurality of ground engaging members adapted to propel the vehicle over a surface. It may also include a robotic arm comprising a distal portion and a proximal portion coupled to the frame, and an implement, such as a tool or hoe connected to the distal portion of the robotic arm. The implement can be raised and lowered, and also moved relative to the surface by the robotic arm by pivoting or rotating the robotic arm at or near the proximal portion.

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.

An adjustable frame assembly of a planter includes a main frame, a first frame member movably coupled to the main frame, and a drive mechanism operably coupled between the main frame and the first frame member for moving the first frame member along the first axis relative to the main frame. The first frame member is laterally movable along a first axis which is perpendicular to a direction of travel of the planter. The frame assembly also includes a first arm having a first end and a second end, the first end being coupled to the main frame and the second end being coupled to a first row unit. A second arm is provided having a first end and a second end, where the first end is coupled to the first frame member and the second end is coupled to the first row unit.

In one aspect, a system for controlling an operation of agricultural implements may include a work vehicle configured to tow an implement. The work vehicle may include a hitch assembly having a draw point configured to be coupled to the implement. The work vehicle may further include an actuator configured to move the draw point relative to the hitch frame to adjust the position of the implement relative to the work vehicle. The implement may include a sensor configured to detect an operational parameter indicative of the operation of the implement. Additionally, the implement may further include a controller communicatively coupled to the sensor, with the controller being configured to initiate control of an operation of the actuator based on sensor data received from the sensor to adjust the operational parameter of the implement.

In one aspect, a system for controlling ground-engaging tools of an agricultural implement may include first and second ground-engaging tools configured to perform first and second operations, respectively, on a field as the agricultural implement is moved across the field. Furthermore, a controller of the disclosed system may be configured to determine a first value of a field characteristic based on the received sensor data and adjust an operating parameter of the first ground-engaging tool based on the determined first value. After adjusting the operating parameter of the first ground-engaging tool, the controller may be configured to determine a second value of the field characteristic based on the sensor data and adjust an operating parameter of the second ground-engaging tool based on the determined second value.

A wheel assembly of an agricultural implement includes a wheel and a wheel frame supporting the wheel. The wheel frame is configured to pivotally couple to a toolbar of the agricultural implement, and the wheel frame is configured to rotate between a lowered position and a raised position. The wheel assembly also includes a mount configured to fixedly couple to the toolbar. In addition, the wheel assembly includes a linkage assembly configured to control rotation of the wheel frame between the raised position and the lowered position. The wheel assembly also includes a fastener configured to selectively engage the mount and the linkage assembly while the wheel frame is in the lowered position to block rotation of the wheel frame.

An agricultural vehicle header suspension having a frame, a plurality of supports extending forward from the frame, an anchor plate, a frame pivot joining the frame to the anchor plate to be rotatable about a frame pivot axis, a frame actuator connected between the anchor plate and the frame and configured to resiliently hold the frame at a predetermined position relative to the anchor plate, and to allow the frame to move through a range of motion relative to the anchor plate, upon compression and/or extension of the frame actuator. The frame actuator may be, for example, at least one single-acting hydraulic actuator, mechanical spring, or a pneumatic cylinder.

An agricultural implement has implement settings for soil engaging tools that are controlled based on measured temporal and long-term soil properties in a field. A controller receives data from various soil and optical sensors and provides decision support for adjusting the implement settings. The soil sensors include a square or modified square electrical array that includes two independent, isolated disk coulters running side-by-side followed by two independent, isolated soil engaging runners. One runner has an optical sensor for organic matter, and the other runner has a temperature and moisture sensor. Above-ground optical sensors can be used to measure soil and plant material ahead of and behind the soil engaging tool. The controller can provide real time alerts to an operator that adjustments to the implement settings are needed, or the adjustments can be made automatically based on operator set thresholds, factory settings, or historical individual or global grower adjustments.

Implementations are disclosed for adaptively adjusting various parameters of equipment in unpredictable terrain, such as agricultural fields. In various implementations, edge computing device(s) may obtain a first image captured by vision sensor(s) transported across an agricultural field by a vehicle. The first image may depict plant(s) growing in the agricultural area. The edge computing device(s) may process the first image based on a machine learning model to generate agricultural inference(s) about the plant(s) growing in the agricultural area. The edge computing device(s) may determine a quality metric for the agricultural inference(s). While the vehicle continues to travel across the agricultural field, and based on the quality metric: the edge computing device(s) may trigger one or more hardware adjustments to one or more of the vision sensors, or one or more adjustments in an operation of the vehicle.
