Realistic 4×4 Traction System V1.4

Multiplayer in development, playable but may contain bugs Take real control of your tractor’s traction — engage 4×4, lock the differential and let the system react to actual wheel slip, not just to an assigned key. This mod adds a fully switchable 4×4 traction system to compatible vehicles (tractors, trucks, harvesters, cars): engage/disengage the front axle when needed and toggle a differential lock that trades turning radius for maximum grip in mud, snow or during heavy work. Features - Real rear-wheel slip detection — automatic modes react to actual 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, while manual control is always available - Automatic — the same logic, adjusted 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 any other mod - 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 V1.4.0.0 New - Physical traction prediction (tractors with GPS): compares the required force (slope, rolling resistance, effort from LOWERED implements) with rear axle grip, according to the soil type and ground moisture. - Front axle engagement by clutch on a ramp (~0.4 s), without jolts. - Differential lock in 3 positions (Ctrl+K): open / rear / rear + front, with progressive engagement. - Auto/smart: engages with the implement lowered in the field, when wheels are slipping, downhill with a load and at low speed under load; disengages during tight headland turns and at road speed; remains engaged for at least 6 s (no “flashing on and off”). - Automatic locks while working; they release when turning, braking or above 15 km/h (in all modes, for safety). - Maximum speed with 4×4 engaged: 25 km/h (tractors/harvesters), 40 km/h (trucks/cars). - No mode engages 4×4 above 20 km/h, not even with Ctrl+J. - Tyre pressure (Fendt) follows field/road conditions, like the real VarioGrip. - New HUD: live wheel slip, padlocks on locked axles and the REASON for each decision; Fixed - The terrain prediction remained high (e.g., 27%) simply because a heavy implement was attached, even when lifted. - Braking activated 4×4 and the locks (wheel slip while braking no longer counted as a lack of traction). - Multiplayer: Ctrl+J in automatic modes was undone by the dedicated server. - Semi-automatic mode never disengages on its own (only the player can do so).
