How to test the mod:
1. Choose a rear-wheel-drive (2×4) tractor in Manual mode
2. Accelerate uphill or on soft terrain
– The rear wheels will spin
– TThe HUD shows wheel slip
3. Switch to Semi-auto or Automatic
– TThe mod detects actual wheel slip
– T4WD engages automatically
– TThe HUD switches to 4WD
– TThe wheel slip disappears
4. Test Smart mode (Fendt)
– T4WD increases gradually according to the amount of wheel slip
– It is not simply on/off — it is progressive
– TA dream that took years to become reality.
4×4 Traction System (v1.0.1.0)
Take real control of your tractor’s traction — engage 4WD, lock the differential, and let the system react to actual wheel slip, not just a keybind. This mod adds a fully switchable 4×4 traction system to compatible vehicles (tractors, trucks, harvesters, cars): engage/disengage the front axle on demand, and toggle a differential lock that trades turning radius for raw grip in mud, snow, or heavy pulls.
Features
– Real rear-wheel slip detection — the automatic modes react to actual wheel slip physics, not just speed
– Four drive modes, assigned per vehicle out of the box:
– Manual — you’re always in control
– Semi-auto — engages on real slip, manual override always available
– Auto — same logic, tuned for vehicles with factory-automatic 4WD (CVT/IVT drivetrains)
– Smart — Fendt-style continuous, proportional engagement (no hard on/off)
– Native tire pressure simulation on engagement — no dependency on any other mod
– On-screen HUD with live status, adjustable position from the in-game Settings menu
– Zero XML edits to any vehicle — the system injects itself into every compatible vehicle automatically
V1.0.1.0
– Keybinds changed to Shift+Ctrl+J/K/N to avoid conflicts with other mods
– Auto/semi-auto response is much faster (confirm delay cut from 2.5s to 0.9s)
– The 2WD↔4WD switch in manual/semi-auto/auto is now a short smooth ramp instead of an instant on/off — no more jolt or momentary speed loss when the front axle engages under load
– Optional soft compatibility with Hyper Realistic Maintenance 2, if you also run it (see below) — fully standalone otherwise
