I found a very suitable Caterpillar engine and adjusted it to the tractor as much as possible. Yes, there are no hoses from the radiator, but it doesn't matter, I'm too lazy to climb into the blender once again.
The tractor's functionality has not changed. I just added the Caterpillar C9 sound and the engine itself. I will immediately answer for the archive size of 120 MB, almost 80% is the engine, it is highly polygonal (made as light as possible), so now there is a size warning in the log, but it does not affect the optimization in the game.

Price: $156,000
Power: 390 hp
Configuration:
- Bus configuration
- Lighthouses
- Main body color
- Rim color
- Seat color
