Hello All,
Since we now have tractor tires, let's build some tractors!
Here is my version of the Case 620 HD farm tractor, rated at 620 hp and designed for large farms:
First, the real thing:
Now the Lego version:
This tractor features 4 pneumatic remotes, as well as pneumatic steering controlled by a servo and switch. Other features include seperate PTO, drawbar, recovery cable, opening hood and pivoting center section.
It is driven by one XL motor, and the pto and air pump are powered by M motors. There wasn't room under the hood for two receivers, so an sbrick is used to control all functions.
