An auxiliary track device for movement of a vehicle. The auxiliary track device may enhance traction and/or floatation of the vehicle, such as, for example, by being installable on the vehicle to convert the vehicle into a tracked one and/or by being deployable to engage the ground in certain situations, including where additional traction and/or floatation may be desirable based on an environment of the vehicle such as one or more characteristics of the ground (e.g., a compliance, such as a softness or hardness, a slipperiness, a soil compatibility, and/or a profile of the ground), a state of the vehicle (e.g., a speed of the vehicle, loading carried by the vehicle, etc.), a user's preferences (e.g., ride quality, etc.), and/or any other suitable factor. The auxiliary track device may be used only for traction and/or floatation of the vehicle or may be part of an implement to perform work with the vehicle.

An autonomous vehicle platform system and method configured to perform various in-season management tasks, including selectively applying fertilizer, mapping growth zones and seeding cover crop within an agricultural field, while self-navigating between rows of planted crops and beneath the canopy of the planted crops on the uneven terrain of an agricultural field, allowing for an ideal in-season application of fertilizer to occur once the planted crop is well established and growing rapidly, in an effort to limit the loss of fertilizer.

A self-propelled agricultural working machine comprising: a drive module with a load-bearing chassis; agricultural implements for performing an agricultural operation; an electronic control unit for controlling the ground-engaging member; and an operator station with an operator interface, the operator station configured to be removably attached to the load-bearing chassis.

A tractor with a chassis comprising a drive unit, a drive gear, a drivable rear axle assembly, a front axle assembly and a front attachment assembly. The front axle assembly comprises an axle drive housing and two wheel suspensions mounted thereon, on which front ground engagement means is positioned. The tractor further comprises a cooling system for cooling the drive unit. The axle drive housing is arranged between the drive unit and the front attachment assembly viewed in the longitudinal direction of the tractor. The cooling system is arranged above the axle drive housing and, viewed in the longitudinal direction of the vehicle, completely between a front, vertically extending plane tangent to the envelope curves of the front ground engagement means in the straight-ahead position, and a rear, vertically extending plane which is tangent to the envelope curves of the front ground engagement means in the straight-ahead position.

A self-propelled agricultural work machine comprising: an energy source; a ground engaging element configured with a drive train, the ground engaging element further configured to be driven in a normal operating mode by at least one of the energy source and drive train; a carrying frame supported on the ground engaging element; and a control unit in communication with an actuator configured to steer the ground engaging element, the control unit configured to transmit signals so as to specify a steering angle of the ground engaging element and, in the event of a failure of at least one of the energy source or the drive train, the control unit configured to operate in a towing mode in which the control unit controls the actuator based on the signals from a sensor so as to detect the angle between a tow bar of a towing vehicle and the agricultural work machine.
