Barn With Cowshed

A large Polish barn-shed, housing 60 cattle.
The barn already has a built-in manure silo with a capacity of 75,000 liters, use the front loader to push the manure apart and increase its capacity a bit.
Attention:
-Manure extractor animation is unavailable if you don't open the door!
-Price: 75,000 $
-Cost of living: 200 $ per day
Many thanks JMZ for your help!
