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 implement frame having a carriage frame for coupling to a towing vehicle and wheels to support the frame for movement over a ground surface. A pivot frame is rotationally mounted to the carriage frame and a lift assembly is coupled to the pivot frame via a shift assembly. A tool bar is mounted to the lift assembly. The shift assembly moves the tool bar forward as it is moved from the field use position to the transport position. The wheels are mounted to swing arms to move the wheels inward for a narrow transport position. All motion is accomplished through actuators, such as hydraulic cylinders, to automate the process making it quick and easy.

A system for irrigating an agricultural field includes a high-clearance vehicle (e.g., a sprayer vehicle) and a hose configured to connect an external water source to the high-clearance vehicle while the high-clearance vehicle traverses the agricultural field. A method for irrigating an agricultural field includes connecting an external water source to a high-clearance vehicle by a hose, and dispensing water from the nozzles of the high-clearance vehicle while the external water source remains connected thereto and while the high-clearance vehicle traverses the agricultural field.

A system for adjusting the lateral positioning of wheel assemblies of agricultural implements includes a toolbar extending in a lateral direction and having a substantially circular cross-sectional shape. The system also includes a rail coupled to the toolbar and extending in the lateral direction along a length of the toolbar. Additionally, the system includes a wheel assembly configured to be removably coupled to the toolbar such that the rail is positioned between the toolbar and a portion of the wheel assembly. The wheel assembly includes engagement structure configured to engage the rail when the wheel assembly is installed relative to the toolbar, with the engagement between the rail and the engagement structure being configured to prevent rotation of the wheel assembly about the toolbar.

A mounting assembly for a gauge wheel on a row unit allows for infinite lateral adjustment of the gauge relative to an opening disc on the row unit. The mounting assembly includes an arm with a threaded bore extending through a split end of the arm. A threaded bushing is adjustably mounted in the bore and secured in a desired position with a bolt standing through the split end to clamp bushing in position. The split end mounting arm provides a method of quickly and easily adjusting the lateral position of the gauge wheel on the row unit in infinite increments.

A wheel-mounting assembly for a utility vehicle includes a chassis and a wheel support assembly mounted to respective outboard ends of first and second telescopic axle assemblies. The first and second telescopic axle assemblies are laterally spaced from one another and are each secured to the chassis. The first and second telescopic axle assemblies each include a respective actuator arranged to control extension and retraction thereof for steering and track-width control.

A soil cultivator comprises a frame attachable to a tractor and at least one processing unit attached to the frame. The processing unit has a frame-like element, a first soil cultivation tool attached to the frame-like element via a first connecting element, a second soil cultivation tool attached to the frame-like element via a second connecting element, and a swiveling axis element. The first soil cultivation tool and the second soil cultivation tool are arranged on different sides of the swiveling axis element. The first connecting element has a first annular section, and the second connecting element has a second annular section. The first and the second connecting elements are arranged so that they can swivel around the swiveling axis element such that a change in the extent of the frame-like element can effect a change in the distance between the first and the second soil cultivation tools.

A wheel-mounting assembly for an agricultural utility vehicle includes a chassis and a telescopic axle arrangement fixed to the chassis. The telescopic axle arrangement includes an inner axle telescopically received in an outer axle, which is fixed to the chassis. A wheel-support assembly is mounted to an outboard end of the inner axle. A steering-control actuator is connected between the inner axle and the wheel-support assembly. The steering-control actuator is connected to the inner axle through an opening provided in the outer axle, which allows the steering-control actuator to translate together with the inner axle when track width is adjusted.
