Features: 4-wheel drive, diff-lock and portal axles
When the Claas tires (109 mm tractor tires) were presented by LEGO I knew that I need to build an agricultural Unimog with off-road capabilities. The present model has portal axles, front and rear diff-lock, two speed transmission, winch and old school lock. It worked well and had a lot of ground clearance. I built a transmission without back lash for optimal power transmission. There was almost no back lash in the transmission but shifting gears didn’t work so well. The model has the following functions:
- Driving: 2 x PF XL motor
- Steering: 1 x PF servo motor
- Winch: 1 x PF L motor
- Diff-lock: 1 x PF M motor with auto-valve
- Control: 2 x SBrick
