Multiplayer is in development and playable, but may contain bugs. This mod adds a fully switchable 4×4 traction system to compatible vehicles, including tractors, trucks, harvesters and cars, with front axle engagement, differential lock control and wheel-slip-based reactions.
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, using the same logic adjusted for vehicles with factory-fitted automatic 4WD, CVT/IVT transmissions.
- Intelligent, continuous and proportional engagement in the Fendt style, without abrupt switching on or off.
- Native tyre-pressure simulation during engagement, with 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, as the system integrates automatically into all compatible vehicles.
Changelog
V1.4.0.0
New
- Physical traction prediction for tractors with GPS: compares the required force, including slope, rolling resistance and effort from LOWERED implements, with rear axle grip according to the soil type and ground moisture.
- Front axle engagement by clutch on a ramp, approximately 0.4 s, without jolts.
- Differential lock in 3 positions,
Ctrl+K: open, rear, and 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. It disengages during tight headland turns and at road speed, and remains engaged for at least 6 s, with 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 for tractors and harvesters, and 40 km/h for trucks and cars.
- No mode engages 4×4 above 20 km/h, not even with
Ctrl+J. - Tyre pressure, Fendt, follows field and road conditions, like the real VarioGrip.
- New HUD with live wheel slip, padlocks on locked axles and the REASON for each decision.
Fixed
- The terrain prediction remained high, for example 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.
- In multiplayer,
Ctrl+Jin automatic modes was undone by the dedicated server. - Semi-automatic mode never disengaged on its own. Only the player can do so.
