An autonomous agricultural robot, referred to as robot, including: a straddle chassis defining an aisle through which a row of crops can pass, propulsion means for moving the robot in a direction of forward travel, a control unit for controlling the robot and an obstacle-characterization device. This device including: obstacle detection means which are configured to detect an obstacle lying in the path of the autonomous agricultural robot, a processing unit configured so that when an obstacle is detected by the obstacle-detection means, the unit logs the data collected by the obstacle-detection means, and/or processes the data collected by the obstacle-detection means and determines at least one characteristic of the detected obstacle.

A row-crop tractor including a tractor frame structure having a front portion and a rear portion. Two front wheels are rotatable mounted to the front portion of the tractor frame structure. At least a rear wheel is mounted to the rear portion of the tractor frame structure. A drive mechanism is mounted to the front portion of the tractor frame structure and connected to the two front wheels for controllably driving the same in dependence upon a control signal received from an operator of the row-crop tractor such that one front wheel is driven independent from the other. A front farm implement connecting mechanism is disposed at a front end of the front portion of the tractor frame structure and an operator seat mounted to the front portion of the tractor frame structure in close proximity to the front end of the front portion of the tractor frame structure such that the operator of the row-crop tractor is enabled to reach a front farm implement connected to the front farm implement connecting mechanism.

A tractor for agricultural use includes a chassis, which connects a front tractor part and a rear tractor part to one another via a connecting element, a driver's seat in the region of the rear tractor part, a drive and at least four wheels. The connecting element of the chassis, which connects the rear and the front tractor parts to one another, is disposed at least 60 cm above the driver's seat and extends substantially horizontally up to the front tractor part. The driver can thus look to the right, and also at an implement disposed behind the front tractor part, below the connecting element. This enables precise maneuvering when tilling the soil for rows of plants.

An agricultural vehicle includes a chassis, a plurality of ground-engaging elements configured to support the chassis above a ground surface, and a plurality of support assemblies supporting the chassis on the ground-engaging elements. Each support assembly includes a height-adjustment actuator. A controller is configured to adjust the height-adjustment actuators independently of one another and transfer a load from a first ground-engaging element to other ground-engaging elements. A method of operating an agricultural vehicle includes receiving a command to transfer a load from a first ground-engaging element to other ground-engaging elements, adjusting at least one height-adjustment actuator, and transferring a load from the first ground-engaging element to the other ground-engaging elements.

A machine includes a chassis, a plurality of ground engaging elements supporting the chassis above a ground surface, a motor for driving at least one of the ground engaging elements and a plurality of assemblies supporting the chassis on the ground engaging elements. Each of the assemblies is configured to selectively raise and lower the chassis relative to the ground surface and includes a first attachment component for attaching the assembly to one of the ground engaging elements, a second attachment component for attaching the assembly to the chassis, an adjustment component for shifting the first attachment component between a plurality of operating positions relative to the second attachment component. A control system allows an operator to remotely control the adjustment components of each of the assemblies.

A suspension module includes a spindle pivotably connected to an axle with a pivot element defining a vertical axis. The spindle has an attachment member and an attachment cap, with outer ends are rigidly interconnected by a pair of lift cylinders. The spindle includes a plate extending between the lift cylinders intermediate the attachment member and cap with the pivot element received between the attachment member and plate. Each lift cylinder has a ram movable within a housing of the lift cylinder. A wheelbox mounts to the wheel and couples with the spindle. First and second strut rods connect the wheelbox with the ram of one of the lift cylinders, and third and fourth strut rods connect the wheelbox with the ram of a second lift cylinder. The strut rods allow the spindle to move relative to the wheelbox while also transferring pivot torque between the wheelbox and the spindle.

An assembly for supporting a vehicle chassis on a wheel of the vehicle includes a wheel attachment component for attaching the assembly to a wheel, a chassis attachment component for pivotably attaching the assembly to a chassis of the vehicle, and a suspension component operably interposed between the wheel attachment component and the chassis attachment component. A first adjustment element is coupled with the chassis attachment component and coupled with a first portion of the suspension component, and a second adjustment element is coupled with the chassis attachment component and coupled with the first portion of the suspension component. The first and second adjustment elements are configured to shift the first portion of the suspension component between a plurality of operating positions relative to the chassis attachment component. A single strut bar slidingly engages the wheel attachment component and is rigidly coupled with a second portion of the suspension component.

An assembly for supporting a vehicle chassis on a wheel of the vehicle includes a wheel attachment component for attaching the assembly to the wheel, a chassis attachment component for attaching the assembly to the vehicle chassis, and a suspension component. At least one adjustment element is coupled with the chassis attachment component and with a first portion of the suspension component, and is configured to shift the first portion of the suspension element between a plurality of operating positions relative to the chassis attachment component. A single strut bar is rigidly coupled with the wheel attachment component and with a second portion of the suspension component, and is configured to pivot relative to the chassis attachment component. The suspension component is configured to regulate motion transfer between the wheel attachment component and the chassis attachment component.

A tractor includes a frame defines longitudinal (nominally forward and backward), lateral (nominally left and right), and transverse (nominally up and down) directions (mutually orthogonal). First and second side structures connect by a width adjustment structure comprising beams of bearing length and bearing width capable of supporting loads (torque, bending, etc.) at any of a plurality of widths therebetween. Individual drive systems in the first and second sides each include a track, motor, sprocket, main idler, and bogey idlers. A carrier system secures, lifts, and descends an implement. Implements may be of any type, such as tillage, harrowing, furrowing, seeding, cultivation, personnel carrier, or the like. A controller is capable of directing the tractor based on a pre-determined course of travel, or a guided course in response to physical features in a farming field.

An agricultural vehicle includes a frame and a plurality of suspension assemblies coupled to the frame. The plurality of suspension assemblies configured to together increase or decrease a vertical distance between the frame and a surface supporting the agricultural vehicle. The agricultural vehicle also includes a plurality of wheels. One wheel of the plurality of wheels is coupled to each suspension assembly, and at least two wheels of the plurality of wheels are movable about a steering axis. The agricultural vehicle further includes at least two actuators. Each of the at least two actuators is coupled to a respective suspension assembly of the plurality of suspension assemblies and is configured to move one of the at least two wheels.
