Realistic 4×4 Traction System V1.5 fs25-mods

Description:

Multiplayer in development, playable but may contain bugs. Take full control of your tractor’s traction — activate 4×4, lock the differential, and let the system respond to actual wheel slip, not just a preset key. This mod adds a fully switchable 4×4 traction system to compatible vehicles (tractors, trucks, harvesters, cars): engage or disengage the front axle as needed and toggle a differential lock that balances turning radius with maximum grip in mud, snow, or heavy work. Features
Real rear-wheel slip detection — automatic modes respond to real wheel-slip physics, not just speed.
Four driving modes, assigned to each vehicle by default:
- Manual — always in control
- Semi-automatic — engages with actual wheel slip, manual control always available
- Automatic — same logic, optimized for vehicles with factory-fitted automatic 4WD (CVT/IVT transmissions)
- Intelligent — continuous, proportional engagement in the Fendt style (without abrupt switching on/off)
Native tyre-pressure simulation during engagement — no dependency on other mods
On-screen HUD with real-time status and adjustable position in the game Settings menu
Zero XML changes to any vehicle — the system integrates automatically into all compatible vehicles

V1.5.0.0
NEW / FIXED
- Differentials now truly work: rebuilt on the drivetrain node exactly as the game creates them (in FS25, previous locks had no effect)
- Separate FRONT / CENTER / REAR diff locks (Ctrl+Alt+K / Ctrl+Alt+J / Ctrl+Alt+L) + quick cycle (Ctrl+K), all rebindable
- Locked center respects the real front-axle lead (tyre size ratio + 2.5%): no more rear wheels spinning while the front brakes the tractor
- 2WD mode leaves the front axle free
- CTIS tyre pressure per axle calculated from real axle load and tyre load tables (with Soil Draft Physics); realistic -3.5% rolling radius instead of -15% (no more “flat” tyres)
- CTIS automatically disabled on tracked tractors
- New translations: DE, FR, ES, IT, PL, RU (plus EN, PT, BR) with Google; some errors expected
Tested together (no conflicts)
- Precision Farming 1.5.1.0
- Soil Draft Physics (beta); when installed, CTIS tyre pressure is calculated from real axle load
- Realistic Mechanical Systems (RMS) 0.10.0.0
- Realistic Weather 1.2.0.0
- Vehicles: Fendt 1000 Vario Series, John Deere 8R Pack / 6R Large / Ripper 2100, Case IH Magnum CVX, Kubota M7, JCB Fastrac 4000, CLAAS Lexion 8000
- Real Three Point Attacher, Remove Frontloader Axle Locking, Vehicle Speed Sync, DashboardLive, Real Vehicle Cams, Universal Autoload
- Maps: Riverbend Springs, Redstone County
Not recommended together (they also change wheels/differentials):
- Mud System Physics, REA Plus, Tractor Terrain Dynamics, Variable Tire Pressure
- EnhancedVehicle: disable its differential/drive-mode functions if used alongside this mod.
