I can't make up my mind which is more impressive the chipper, the grapple, or the smoothness of the operator. I don't think I'd spend any money on those trailers, no door hold backs and shallow dump angles.
No diesel, you can see the butt of the electric motor in the chipper's engine case. Also 2 electric motors to operate the feeding rollers.
The main problem for the dump trailer is that the chips are way too over-sized for the scale, they can't flow out.
Still, I'm completely amazed !
I thought that the guy could be a real operator at scale 1 to have such a control on the grappel.
