A modular autonomous agricultural vehicle includes a drive module having a frame, a ground-engaging element rotatably coupled to the frame, a power source, and a drive motor receiving power from the power source and coupled to the ground-engaging element for rotating the ground engaging element. At least one toolbar module is detachably coupled to the frame for coupling the drive module to an agricultural implement or another modular toolbar segment. The modular toolbar preferably includes multiple toolbar modules coupled to each other in series to form the modular toolbar.

A drive unit is situated between a first wheel axle and a second wheel axle and has an internal-combustion engine with a crankshaft system including a horizontally oriented crankshaft, which crankshaft acts upon a continuously variable transmission system which drives wheels of the first wheel axle and of the second wheel axle. The crankshaft is caused to rotate by at least one piston of the engine. The crankshaft interacts with a first set of V-pulleys of the transmission system, which first set of V-pulleys, by way of a first drive shaft, is connected with a first differential of the first wheel axle. The first set of V-pulleys, by way of an endless member, is in an operative connection with a set of V-pulleys which, with the interposition of a second drive shaft, influences a second differential of the second wheel axle.

In one embodiment, a vehicle platform comprises a central body that can support one or more implement configurations, such as sprayer booms, or planting row units. A plurality of adjustable legs extends downward from the central body. Each adjustable leg has a corresponding leg actuator to adjust a respective vertical height of each adjustable leg. Each adjustable leg supports the central body. Planting row units are supported by or suspended from the central body.

An autonomous vehicle platform and system for selectively performing an in-season management task in an agricultural field while self-navigating between rows of planted crops, the autonomous vehicle platform having a vehicle base with a width so dimensioned as to be insertable through the space between two rows of planted crops, the vehicle base having an in-season task management structure configured to perform various tasks, including selectively applying fertilizer, mapping growth zones and seeding cover crop within an agricultural field.

A vehicle combining the attributes of a tractor and a utility vehicle includes a three point linkage and other locations to which a plurality of attachments for performing grooming or working operations on a ground or turf surface may be couple. The vehicle includes a front mounted engine, a mid-mounted operator compartment and a rear mounted bed or box. A PTO shaft and/or a hydraulic power system of the vehicle power attachments that require power. A control system and a visual display and data entry device linked thereto are provided for allowing an authorized person to setup, store and thereafter use an operational profile for each attachment that is to be coupled to the vehicle. In a rate dependent attachment, the control system maintains the ground speed and the attachment implement in a fixed ratio. A down/up control is used to signal the start and end of an operational sequence to the control system.

Disclosed is an autonomous agricultural carrier vehicle including a frame construction with mounting devices configured to carry and guide at least one agricultural implement; at least two chassis constructions which are mounted on the frame construction; a drive apparatus having a drive train which is coupled to the least two chassis constructions and is configured to specify a driving speed; and a control apparatus and an environment sensor system which is signal-connected and/or signal-connectable to the control apparatus. The chassis constructions are preferably mounted rotatably about at least 90 about vertically oriented axes. Also disclosed is an autonomous agricultural machine in combination with the autonomous agricultural carrier vehicle.

A wheel assembly is for a unitractor. The wheel assembly has a wheel, a static hub and an internal electrical motor. The wheel has a rim, a traction member arranged to the periphery of the rim and a plurality of magnets arranged to the inside of the rim. The hub has a stator having spherical windings. The wheel is rotatably connected to the hub via at least one bearing. At least one side panel extends from the rim and to the at least one bearing. At least one of an energy source and a controller for controlling the energy source is positioned in the hub. The hub is provided with a coupling member for an implement frame. A unitractor having the wheel assembly is also described.

Vehicles having the versatility to be used as farm vehicles while also being able to be used as a transportation method, such as a motorcycle, are provided. The vehicles can generally include a three-wheel configuration in which first and second drive wheels are substantially vertically aligned, and the third wheel is offset from the vertically aligned drive wheels. The third wheel can be aligned with the second wheel, or it can be disposed at a location that is between the first and second wheels while still being offset from the vertical alignment. A tool for performing farming actions is also provided. In some instances the tool can be laterally offset from the vertically aligned wheels, located between the drive wheels, while in other instances the tool can be disposed distal of the rear wheel. Many vehicle and tool configurations are disclosed, as are methods for operating the same.
