This began as a conversion from FS19. I couldn't get permission to release my conversion, so I decided to build one instead. I learned a lot with this mod, most importantly, to create a backup. 
This is a first-generation John Deere 7R that has the Trike conversion, which is a real-life modification. It transforms the 7R into a zero-turn tractor. I highly suggest using either the wide wheel with weights or the twin wheel set-up, as they make the tractor more stable. I'll add more tire selections later on. 
This is the first of three trikes I plan on. The second will be a first-generation John Deere 6R and then a John Deere 4755. Why these three? They are the only real-life examples I could find. It's also why I'm using the first-generation 7R and 6R as those are the ones I could find that had this conversion. 
This should be error-free. I had no issues with it in game, or during testing, so it should be all set to go.
