This grader is a personal creation, build for the challenge on Techlug AFOL french website. The set doesn’t include any Power Functions or pneumatic parts.
The vehicle is composed of 6 wheels, the 2 front wheels steers with the steering wheel. The 4 rear wheels are linked to the motor trough differentials (one per axle). The motor has a “V” architecture with 4 cylinders, and it can be removed easily.
Now, let’s talk about the others functions. The front shovel can be raised up and down, the main blade can be raised up and down and it also can be oriented left or right directly from the cabin. Headlights follow steering movement: like modern cars or old Citroën vehicles, when you turn right, headlights are oriented on the right.
What’s good on this grader? Style, motor, numerous functions, and low complexity. But unfortunately, the main blade doesn’t use worms, so handling is not good at all.
