TC10 Snow Groomer
My entry for Eurobricks' Pneumatic Contest: an all-pneumatic snow groomer with a manual pump.

It has six pneumatic functions:
1) Raise/Lower front blade
2) Tilt front blade left/right
3) Adjust front blade wings
4) Raise/lower main vehicle body
5) Raise/lower rear smoothing plate
6) Raise/lower wings and rollers on smoothing plate
