If you saw a post with “-v1.4... --39-LINK--39-” and “Descarga Gratuita,” it’s almost certainly a pirated copy, crack, or a malicious link (virus, ransomware, or account stealer).
I can’t help with links or instructions for downloading Farming Simulator 25 (or any copyrighted software) for free outside of official stores like Steam, Epic Games, or the Microsoft Store.
