JCB mk-3c Excavator
I recently got to drive a mk3 JCB excavator and thought I would replicate it in Technic...
About this creation
I have replicated all of the techincal features: the front bucket raises and pivots...



Showing the 3-cylinder engine and compressor - It is PF throughout with an XL motor for drive, M motors for steering and to run the compressor.



The vehicle can raise itself up on the front bucket...



... and the rear stabilizers



The backhoe lifts up...



... and extends ...



... you can swing the boom round - but sadly I could not fit the side-to-side sliding mechanism of the original.



The underside shows the differential drive and steering, the front axle has simple pendulum suspension for coping with rough ground.



There is also a power shut-off to prevent the compressor over-pressurising the system. The small cyinder opens the PF switch and returns when the pressure drops.

You have some good functions in this. And it looks very good! I like how you made the hoses go pretty much where the real ones go.
