Realistic 4×4 Traction System V1.1 fs25-mods

Description:

Take full control of your tractor's traction—engage 4WD, lock the differential, and let the system respond 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): activate or deactivate the front axle on demand, and toggle a differential lock that balances turning radius with grip in mud, snow, or heavy pulls. Features - Real rear-wheel slip detection — 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 automatically injects itself into every compatible vehicle. V1.1.0.0 Fendt Vario Grip Smart remains unchanged for now. More details on how it works are coming. New Features - Automatic differential lock - In "Auto" and "Smart" drive modes, the center differential lock engages and disengages automatically under severe wheel slip at low speeds (never on the road). "Semi-Automatic" and "Manual" modes still require Ctrl+K. Shop upgrade: Semi-Automatic to Automatic - Tractors configured as "Semi-Automatic" now offer a new upgrade option in the store’s Customize screen, allowing you to pay to upgrade that specific unit to full "Automatic" behavior (including automatic diff lock). This clarifies the difference, as many players didn’t realize Semi-Automatic and Automatic tractors behave differently. The options are now clearly labeled: - Semi-Automatic (Diff Lock Manual) — free, default. - Automatic (Diff Lock Automatic) — paid upgrade. Known Issues - Some vehicles may need tweaks or fixes; not all have real or near-real specs. - Compatibility not fully confirmed with other mods, especially those involving tractors or maintenance scripts, except my maintenance mod. Fixes - Excluded three grape harvesters with independent hydraulic wheel motors (ERO Grapeliner Series 7000, New Holland Braud 9070L, Gregoire GL) — these are always all-wheel-drive by design, so the mod no longer applies to them, nor to crawlers and tracked vehicles. - Crawlers and tracked vehicles no longer get 4×4 system. Documentation - Clarified the difference between "Semi-Automatic" and "Automatic" modes in the in-game HUD hints, configuration comments, and readme: both automatically engage/disengage the 4×4 based on real wheel slip. The actual difference is that only "Automatic" (and "Smart") also lock the differential automatically. Compatibility - Singleplayer only. No changes to save-game compatibility. Existing installs can update directly.
