Features drive by a single cylinder engine, clutch, steering and front suspension.
This moc was designed to be shown at Fana’briques 2011, the most important lego exhibition in France. The aim was to built a “kinematic” moc in order to have parts in motion. The other aim was to have visible gears to get a more attractive vehicle. Consequently, the moc is powered by a single pneumatic cylinder engine which provides 1w of power (at 3 bars of pressure). The basic principle is based on old steam vehicles or tractors. Then, a remoted clucth by a small cylinder provides the power on the rear wheel (with the main chain). The steering is operated by the steering wheel in the cab with a 8t/screw and lever system (through the chassis). The front suspension is made with a flex part on a live axle. Finally I have had details like the centrifugal governor or the tank (which hides the Air-tank).
Concerning the driving, a hand pump with 4 pumps gives power to the engine. The engine runs smoothly thanks to the inertia wheel. The engine is quite reliable, during 3 days of exhibition, the engine have run without problem. Through this moc, I think the LPE moc is a good example for a demonstration of what it is possible to do in lego (such as in an exhibition).

[…] to build another tractor to improve the previous and use a single engine with inertia wheel as on my pneumatic machine. The result is here : a pneumatic single engine tractor with a special feature : adjustable […]
I meant surfsupall@gmail.com
I’m sorry but I still don’t understand what to do can you send to surfsupallan@gmail.com. I spent over 100 dollars u.s. To make this model this is very important.
There is an axle 7 stud.
I was wondering what goes to the back pneumatic switch because one of the “pins” on it has nothing on it.
Is the large inertia wheel the skinnier version or the thick version. Please email me back THIS IS URGENT!
Do you need a air tank to make this model work. Thank you for emailing back
It moves because I command with a pump and a switch outside the model (remoted). Regards
Sorry no, the model is taken apart. Regards
Do you think you can maybe post better instructions.
How does the mini pneumatic pump move automatically

will u let me buy it off u please send a price to l.leno@sky.com
Very nice work!
Bascally :
The pressure goes from hand pump to main switch.
Pressure goes to main switch to air tank (lower end)
Then pressure goes from the upper end of the air tank to the second switch (which control the cylinder)
Then 2 hoses go from the second switch to the cylinder.
hello
beautiful model,but the instructions very leave to wish
I do not understand like and where to connect the pneumatic hose leaving from the tank.
you can send a clear scheme to me?
many thanks
