Some time ago I started building John Deere 8RX model in 1:17 scale. Unfortunately, due to the difficulty of the model, the scope of the work is very slow.
The project assumes rear and front three-point linkage, rear PTO driven by 2-3 m motors, one pneumatic output, 4x4 drive - XL or L motors ( if I have enough space), steering with servo motor, everything controlled by 2 sbricks.
One of the biggest problems with this model that I encountered at the very beginning of the project was the drive of the tracks and the exact representation of all its moving elements. The second problem is the 8RX mask and its curvature. This is my 3rd mask concept. Now I'm waiting for the green bricks to finish the prototype of the mask. And move on to body design .
