As promised, I made a Huerlimann XM4Ti tractor from FS 18 in Farming Simulator 20 Mobile. The mod turned out cool, but there is no animation as such.
In order for the engine to be identical to the FS 18, you need to put "Motor 2" in the configuration. The Huerlimann XM4Ti mod itself from the game FS 19 seems to be. It has configurations: Wheel, Motor, FillUnit, FrontLoader.
