Just a piece of advice. Whenever you add something to an i3D file, always place it at the end of the existing shapes. I had a look at the i3D for this Zetor, and I'm actually surprised it works at all. For example, the beer you added inside the cab was inserted higher up in the hierarchy, which isn't the right way to do it. By doing that, you shifted the indices of everything below it. You also completely removed the placeholder for the front license plate, which is why it's showing up incorrectly. Its index now points to the drive belt instead.
Great trailers, and thank you for your hard work! Just a small note for those asking or complaining that unloading from the combine doesn't work. The standard and low sideboards are intended for bulk materials, while the tallest sideboards are designed exclusively for chopped forage (silage, grass, etc.) and similar lightweight materials. 😉
