Required Mod:
UniversalProcessKit from 0.9.8

Procedure:
1) Hole shoveling:
Driving with a shovel on the mound and shovel the hole. 12000 l manure located therein. These can be loaded into a spreader, or simply dump next to the hill, but then it is just gone.
To make it usable again for the standard maps I used manure... You can change it in sand, gravel, etc. yourself.
The hole must be completely empty, so you can deliver woodpallets or woodChips.
