The volume of liquid manure in the barn prevents the manure plain from moving, therefore I constructed a manure lagoon.
Since the lagoon and the liquid manure trigger are the same size, you utilize the manure pump from Custom Modding.
If a manure trigger is added, solid manure may be forced into the pit.
The little barns in the pack have been taken out.
The pasture version of the barn, which is from Marxville, WI and will enter the lagoon pit, should not be used, according to MRG Mapping.
