Equipment physics, not a mud mod. No settings — everything works automatically.
What is it?
TTD changes equipment behavior based on weather, ground type, moisture, tire wear and tire pressure.
Ground is not the goal — it’s a condition. The tractor is the main character. Wet field — less grip. Plowed soil — more resistance. Asphalt — everything is easy. Just like in real life.
What you get:
– Weather affects your work: rain — field becomes soft, dry — everything is stable
– Ground type changes physics: 17 types from asphalt to plowed field
– Equipment feels different: tracks, duals, wide tires — everything matters
– Transmission works realistically: holds gears under load
– HUD shows moisture, grip and resistance
– Multiplayer: synchronization is in the code
Important to understand:
TTD does not add wheelspin “on demand”. Wheelspin is the result of conditions: wet field, tire wear (if UYT is installed), sharp start or too high speed. If the tractor is new, tires are new, weather is dry — you won’t notice any difference. TTD simply makes physics honest and predictable.
What TTD does NOT do:
❌ No visual mud
❌ Doesn’t just make you slower
❌ No random punishments
Compatibility:
– Tire Pressure — tire pressure management with auto mode
– UseYourTyres — tire wear affects grip
– More Realistic — for maximum hardcore experience
Everything that happens is the result of your decisions, weather and ground.

V1.0.3.1
TTD v3.1 – What’s New
Realistic differential. Your tractor now pulls to one side when one wheel is on soft ground and the other on hard ground. Just like real life – the machine doesn’t just spin dumbly, it behaves differently depending on what’s under each wheel.
Smarter implement hydraulics. Some implements (Horsch, Maestro) used to lift the tractor when the wheels sank in. Now the hydraulics work in float mode – the implement stays on the ground and the tractor doesn’t get jacked up.
Smooth field/road switching. No more jittery physics at the edge of a field. The tractor knows clearly whether it’s on a field or on the road.
Trailers and implements don’t lose connection. No more crashes when deleting a tractor, and physics updates instantly when you attach or detach.
Performance boost. The mod is lighter now – less CPU load, fewer checks every frame. Your FPS won’t suffer.
AI tractors now feel the ground too. Bots sink into plowed soil and slip just like you do. Fair physics for everyone.
V1.0.3.0
Multiplayer support enabled — mod now fully works on dedicated servers
Fixed moisture behavior when game time is paused
Fixed tyre wear synchronization between server and clients
Fixed ground type detection reliability
Fixed manual — all pages now display correctly
HUD: new icon order — moisture, sink, grip, resistance, tyre wear
HUD: sink (wheel sinking) now displayed instead of season
HUD: grey tyre icon “NA UYT” when UYT mod is not active
Physics: ground resistance now depends on wheel sinkage, not directly on moisture
Physics: wheel slip now depends on sinkage, tyre type and tyre wear
Physics: reduced ground resistance for stubble, cultivated stubble, post-harvest and other post-harvest field types
Physics: maximum wheel sinkage increased to 25% (was 20%)
AI: wheel sinking now works when AI is driving
Improved overall network performance
