Hydraulic Suspension System BETA 2 v1.0

Hydraulic Suspension System BETA 2 v1.0

Ever noticed that the tractor front axle in the game feels like a steel beam? Hit a rock and the whole tractor jumps, the wheel barely moves.

This mod gives tractors the hydraulic front suspension they have in real life.

Suspension that really works
The wheel moves up and down over bumps and rocks, and you can see the links, cylinders and shaft moving. The tractor is much more stable and comfortable.

Automatic leveling
Just like real tractors: add front weights or a heavy implement and the front returns to the right height by itself in a few seconds.

Every brand with its own system
John Deere ILS and TLS, Fendt, Claas PROACTIV, Terraglide (Case IH / New Holland / Steyr), MF Quadlink, Valtra, Deutz-Fahr and McCormick. Each one behaves differently, some softer, some firmer.

Driving modes
– AUTO – levels by itself
– WORK – firmer when working in the field or when the front starts bouncing
– LOCKED – stiff axle for front loader work or heavy transport
– MANUAL – raise and lower the front yourself (only on JD ILS and Fendt, like in real life)

Keys
Ctrl+Alt+U – change mode
Ctrl+Alt+↑ / ↓ – raise / lower the front (manual mode)
(can be changed in control options)

Only works on tractors that have this system in real life: medium and large tractors from the listed brands. Small tractors and crawlers stay as they are.

BETA VERSION
The mod is still being tested, especially in multiplayer. lot of work needs to be done, but so far is playable and tweaks and fixes will be released from users feedback and suggestions, If you find a problem, please send me your log.txt file. In multiplayer, I need the log from both the host and the player who joined.

BETA 2
New
– Systems simulated per brand and model, with real data where it is published:
John Deere ILS (8R, independent) and TLS Plus, Fendt 1000 Vario (independent wheels), Fendt 700 Vario (120 mm, level control, manual height), Fendt 300 Vario (80 mm), other Fendt, Claas PROACTIV (85 mm), CNH Terraglide (Case IH / New Holland / Steyr), MF Quadlink (90 mm), Valtra AIRES air suspension, Deutz-Fahr with anti-dive, McCormick IFS (independent), Kubota M7, JCB Fastrac.
– Real rules where known: Terraglide and TLS only level above 1.5 km/h; Terraglide can only be locked below 12 km/h and re-engages by itself above it.
– Rigid (pendulum) front axles really swing: one wheel over a rock tilts the whole axle.
– Independent suspension (JD ILS, Fendt 1000, McCormick IFS): each wheel moves on its own, with camber change on the arms.
– Firmer damping for a moment under hard braking or acceleration, to hold the front (stronger on Deutz-Fahr anti-dive and Claas).
– Manual height (Ctrl+Alt+Up / Down) only on systems that have it in real life.
– Mode and manual height saved with the savegame.
– Settings and per-system profiles in modSettings/FS25_HydraulicSuspensionSystem.xml: created on first start, kept when the mod is updated; you can add profiles for mod tractors.
– With Soil & Draft Physics: WORK mode only when the implement is really pulling (real draft force, default 15 kN).
– Works together with 4×4 Traction System.
– Compatible with MoreRealistic: on the front wheels it controls, the hydraulic suspension owns the spring/damper (MoreRealistic’s load-based spring stays on the other wheels, no more fighting/bouncing at the front); WORK mode uses MoreRealistic’s real draft force.
– Translations for all 25 game languages.

Fixes
– No more “Path not registered” errors in the log when loading/saving the mode and manual height.

Known
– Multiplayer still being tested. Pendulum angle and ILS articulation travel are estimates (no published figures found).
