This is my old Massey Ferguson 7278 from FS22. I converted it with Wrobelmen's assistance.
There may be a few little hiccups and mistakes since this is currently a work in progress.
To get the most out of this harvester, I would strongly advise course play and auto drive since the in-game worker and steering instructions are now broken.
The specifications include: Header 7.6 meters 25 feet; Price: £190000; Power: 306; Capacity: 9500

Changelog: V1.2.0.0 - To make the grain pipe and front feed roller better resemble their real-life counterparts, they were colored red instead of black.
It now functions with the in-game 25-foot free flow after the previous heading was removed.
-modified the inner cabin's color to make it less gloomy and melancholy (still a work in progress)
-modified a number of textures and shaders to make it better resemble its real-life equivalent.
