My attempt at a Caterpillar 584 Forwarder. My goal was to have the arm and steering operated by individual pneumatic auto-valves located in the trailer. I however did not anticipate the amount of wires and hoses involved, so it is a bit sloppy looking. Also the small pneumatic pumps do not really handle the heavy arm very well and it is hard to operate accurately. But it does work, and with a good bit of practice I was able to pick up a log and put it on the trailer. The arm can be extended in and out and the claw is rotated by a micro motor. The front blade is operated manually by a power function switch located in the cab. It also has working suspension on both the tractor and the trailer.
