A digital fence of a work area is generated and loaded into a machine control system that controls an off-road machine. The machine control system detects whether the off-road machine is within a threshold distance of the digital fence and automatically controls operating parameters of the off-road machine when the off-road machine is within a threshold distance of the digital fence.

A system for sensing the angular position of a caster wheel includes a sensor mounted on a bearing which supports a shaft aligned with the rotational axis of the caster. A target on the shaft is detected by the sensor which generates signals indicative of the presence or absence of the target. The position of the target is coordinated with the position of the caster wheel such that the signals are indicative of the angular position of the caster wheel. The target may be a groove extending partially around the shaft and a remaining ungrooved portion of the shaft.

The present invention relates to a motorized machine having a chassis, a suspension system mechanically coupled on the one hand to a wheel of the motorized machine and on the other hand to the chassis, and a steering system configured to transmit the steering to said wheel of the motorized machine through the suspension system, the steering system being in a slide-type mechanical connection with the suspension system along the axis of the suspension system.

Self-propelled vehicles for forming bales of crop or forage material are disclosed. The self-propelled baling vehicles include independently driven real wheels and front caster wheels that allow the baling vehicle to turn with a counter-steer profile. In some embodiments, the center of mass of the formed bale is toward the rear of the vehicle to improve the weight distribution of the vehicle.

To reduce complexity of operation when a working vehicle performs automatic steering, the working vehicle includes a vehicle body to be manually steered with a steering wheel or automatically steered to travel forward or rearward, an operator's seat on the vehicle body, a console located forward of the operator's seat or located on one side of the operator's seat, a first manual operator for automatic steering provided in or on the console, and a second manual operator for automatic steering attachable at a location rearward of the operator's seat.

Provided is a method of automatically combining a farm vehicle with a work machine including confirming a current position of the work machine, moving a farm vehicle into a range having a predetermined radius around the current position, and controlling the farm vehicle, on the basis of a current position and direction of a first coupling unit included in the work machine, so that the first coupling unit and a second coupling unit included in the farm vehicle are coupled to each other.

Communication systems positioned within a cab for agricultural operations include at least one antenna element and a communication module having a cellular modem. A machine (e.g., tractor, combine, etc.) for agricultural operations includes a cab for an operator of the machine and a communication system adjacent a window or roof of the cab.

A valve for hydraulic parallel work systems is provided. The valve includes a first pair of ports, a second pair of ports, a first connection, and a second connection. The first connection is between the first pair of ports when the valve is in a load reaction-enabling state. The first connection transmits a load reaction from a load at a steering actuator to a steering device of a hydrostatic steering circuit. The second connection is between the second pair of ports when the valve is in an electro-hydraulic steering enabling state. The second connection fluidly connects a fluid source to an electro-hydraulic steering circuit.

A hydraulic system for controlling a pair of steerable caster wheels includes a left side actuator and a right side actuator. A rear steering control valve is moveable between a first state for disabling direct control of the left and side actuators and a second state for enabling direct control the left and right side actuators to provide a steer response. A fluid connection continuously connects the pressure source and the fluidic tie rod fluid circuit in fluid communication when the rear steering control valve is disposed in one of the first state and the second state to continuously supply the pressurized fluid to the fluidic tie rod fluid circuit.
