The best tractor mod for the game, it has excellent maneuverability and an interesting engine sound. Under load, the engine sound is realistic.
I made a 1985 Ursus 1614 for MudRunner for free, it has its own sounds and all-wheel drive. This all-wheel drive can also be locked for improved cross-country ability in a swamp with trailers.
The Ursus 1614 model in the MudRunner game has the ability to attach a beacon to the roof of the tractor, and a counterweight in front (what mass is not known). In addition, all default trailers are hooked up, this is all its benefit as a tractor in forestry.
