I have converted for you a Rapid A800C seeder like that of Seryoga (blogger) on the channel “Everyday Life of a Tractor Driver”. Don't forget about Cover0.
I made a large red Väderstad Rapid A 800 C seeder for the FS 20. It also has yellow paint in places.
Such a large seeder fits well into the mobile Farming Simulator. She needs a powerful tractor in the form of a green John Deere.
