A bogie positioning system and method for a work machine. The bogie positioning system adapted to selectively engage a wheel of a work machine to a ground surface through a bogie assembly wherein the bogie assembly may have a front wheel coupled to a rear wheel through a bogie coupling mechanism. The bogie coupling mechanism comprising a beam with a rotary joint. The rotary joint allowing the front wheel to rotate about a rotary axis relative to the rear wheel. The beam is coupled to a chassis of the work machine with at least one actuator coupled to the beam. A control unit is in communication with the bogie assembly, a user input interface, and a plurality of sensors, generating command signals to actuate the actuator based on the input signals, thereby selectively engaging the front wheel or the rear wheel with the ground surface.

A couplable automotive road vehicle includes two front wheels, a chassis having a front part and a rear part, an articulated connection device, and front and rear couplings. A wheel cylinder is defined as the cylindrical geometric shape surrounding the two front wheels when the wheels are not turned. The front part of the chassis includes a chassis beam disposed behind the front wheels, outside the wheel cylinder. The front coupling includes a yaw rigid coupling module mounted on the chassis beam between the two front wheels. The vehicle includes, for each front wheel, a suspension arm mounted on the chassis beam and extending around the wheel cylinder, above same, and a tie rod for controlling the steering device, located above the wheel cylinder.

A right shock absorber and a left shock absorber are provided on outer sides of a left front wheel and a right front wheel that define a steering allowable space therebetween. At a lower portion of the right shock absorber, an outer edge of a right front fender is positioned farther radially outwards than an outer edge of the right front wheel, and a right guide wall that extends from the outer edge inwards is provided in an upper rear area to the left of the right front wheel. At a lower portion of the left shock absorber, an outer edge of a left front fender is positioned farther radially outwards than an outer edge of the left front wheel, and a left guide wall that extends from the outer edge inwards is provided in an upper rear area to the right of the left front wheel.

A spreader sprayer system includes a frame member defining a frame body that has a first side, a second side, a front portion, and a rear portion, a first walking member pivotably coupled to the first side of the frame body, a second walking member pivotably coupled to the second side, a first and second plurality of drive wheels, and at least one spray container. The first plurality of drive wheels are disposed on the first side of the frame body and are operatively coupled to the first walking member. The second plurality of drive wheels are disposed on the second side of the frame body and are operatively coupled to the second walking member. Each spray container is coupled to at least one of the first walking member or the second walking member.
