Here are my textures for the production buildings, translated in English and changed in appearence to fit the buildings.
The signs are for the production of Hay, Silage, TMR, Seed, Fertilizer, Pig Food and Pig Food/Diesel.

V1.1 Added signs for the diesel/pig food factory and the pig food mixing plant. Added solid fertilizer to the seed production. The appropriate file should be renamed tabla2.dds and replace the one in the texture folder in each mod.
