A utility vehicle includes a chassis and a work implement movably coupled to the chassis. An operator support is positioned within an operator cab. The operator support includes a seat and a backrest coupled to the seat. A position of the operator support is selectively adjustable relative to the chassis. The utility vehicle further includes a control system in communication with the operator support. The control system includes a sensor operable to sense a position of the work implement relative to the chassis, and a controller including a processor and a memory. The controller is configured to receive a signal from the sensor representative of the position of the work implement. The controller is further configured to generate a signal to automatically adjust the position of the operator support relative to the chassis based in part on the position of the work implement relative to the chassis.

A ground utility robot and implement attachment apparatus having a ground utility robot, at least one implement, at least one solar panel, at least one battery that is chargeable by the at least one solar panel, a power take-off system that is connected to the ground utility robot and to the at least one implement; where the battery powers said ground utility robot and the implement; a safety system that has a computer, a safety program that utilizes a processing logic on the computer, where the safety program initiates precautionary measures that are carried out by the ground utility robot and the power take-off system if an object comes within a predefined distance from the ground utility robot and implement attachment apparatus.

A working vehicle includes an operator seat, an armrest arranged on a side of the operator seat, and a speed shifter to change a traveling speed. The armrest includes an operation lever to be swung back and forth to cause the speed shifter to perform acceleration and deceleration, and an operation switch to be pressed to cause the speed shifter to perform acceleration and deceleration.
