Here I have a placeable foundation for the Jenz hackers from the Forstmod. Since the hacker with some tree trunks for hiking tends, I have built a foundation that is floating. Pure drive, build and enable backward with the Jenz hackers. Through the concrete limitation no longer walk. As more help on loading the logs a concrete channel as wood tick. Log freely.
There may be difficulties in all trees that have to nudge then again possibly. The hacker is bombproof. I went to the testing with a wheel loader, no wobbling, jerking.
The foundation is floating, rotatable with the keys A and D in the desired direction.
