Mod: Horsch Pronto15m
For everyone who uses this mod on maps with MultiFruits like NF_Marsch, Südhemmen etc. here are a few easy steps to add them to this sowing machine:

1. Extract the .zip of this mod
2. Find the pronto15m.xml and search for the following line:
"<seedFruitTypes>wheat barley rape soybean oilseedRadish grass sunflower maize potato sugarBeet</seedFruitTypes>"

3. Replace it with the following line:
"<seedFruitTypeCategories>sowingMachine planter</seedFruitTypeCategories>"

4. Save and zip the file. You can even change the store name in the xml file so you'll get an "extra" sowing machine with all seeds.

I take no responsibility for any errors this may cause or may not. For me it works.
