FS25 Tractor Terrain Dynamics V1.0.3.7
TTD, Tractor Terrain Dynamics, changes equipment behavior automatically based on weather, soil type, moisture, tire wear and tire pressure.
TTD focuses on equipment physics. Wet fields provide less grip, plowed soil creates more resistance, and asphalt makes driving easier.
Features
- Weather affects your work: rain makes the field softer, while dry weather keeps conditions stable.
- Soil-type physics with 17 types, from asphalt to plowed fields.
- Tracks, dual tires and wide tires affect equipment behavior.
- The transmission works realistically and holds gears under load.
- The HUD displays moisture, grip and resistance.
- Multiplayer synchronization is handled in the code.
- Wheel slip results from conditions such as wet fields, tire wear if UYT is installed, sudden starts or excessive speed.
- No visual dirt.
- TTD does not only slow you down.
- No random penalties.
TTD does not add wheel slip on demand. If the tractor is new, the tires are new and the weather is dry, you will not notice a difference. TTD makes the physics fair and predictable.
Everything that happens is the result of your decisions, the weather and the ground.
The mod archive includes a complete guide describing the physics and containing the author’s contact details.
Compatible with:
- UseYourTyres, tire wear affects road grip.
- More Realistic, for maximum hardcore enjoyment.
V1.0.3.7

- Tracked vehicles now leave ruts just like wheeled ones.
- Completely reworked the wheel sinking system, behaviour is now noticeably smoother and more predictable.
- Fixed an issue where moisture on grass and other natural surfaces was displayed incorrectly.
- Tracked vehicles now behave differently from wheeled ones, tracks sink less, slip less and recover more easily.
- Front wheels of tractors now sink slightly less than the rear ones, just like on real machines.
- Fixed a bug where engine settings could fail to apply to some vehicles.
- Each vehicle now stores its own settings separately and does not affect others.
- Removed unnecessary calculations that could cause frame drops when many vehicles were present on the map.
- Improved overall performance, the game now runs more steadily.
- Cleaned up some old and unused parts left over from previous versions.
- Updated default difficulty values, they are now more balanced.
- HUD now hides together with the in-game interface, the separate toggle button has been removed.
- HUD values now match the actual physics.
- Minor fixes in the interface and settings menu.
V1.0.3.5
- Fixed difficulty saving correctly, which was broken in 1.0.3.4.
- HUD position now stays within screen bounds at any UI scale.
- Removed UYT dependency, all mods, including UYT, Tire Pressure, More Realistic and Moisture System, are now optional.
