Hydraulic Suspension System V2.0.2.1

This mod adds hydraulic front suspension to medium and large tractors that have this system in real life. It is a beta version and is still being tested, especially in multiplayer.

Features

• Suspension that works: the wheel moves up and down over bumps and rocks, while the links, cylinders and shaft also move. The tractor is more stable and comfortable.
• Automatic leveling: when front weights or a heavy implement are added, the front returns to the correct height by itself in a few seconds.
• Systems for John Deere ILS and TLS, Fendt, Claas PROACTIV, Terraglide (Case IH / New Holland / Steyr), MF Quadlink, Valtra, Deutz-Fahr and McCormick. Each system behaves differently, with some softer and 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
• Controls:
  • Ctrl+Alt+U, change mode
  • Ctrl+Alt+↑ / ↓, raise or lower the front in manual mode
  • The controls can be changed in the 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. More work is needed, but it is playable. Tweaks and fixes will be released based on user feedback and suggestions.
• If you find a problem, send the log.txt file. In multiplayer, the log from both the host and the player who joined is needed.

Changelog

• V2.0.2.1
  • New: Manual suspension choice per tractor model, using Left Alt + U > Vehicle > “Suspension for this model”: Auto / Levelling / Pendulum / Original. The choice is saved for every vehicle of that model and applied at once.
  • New: Option “Manual height on all tractors” in the window > Settings. This gives manual height to systems that do not have it in real life, for example John Deere TLS. It is off by default and marked as not realistic.
  • Fix: Tractors with their own vehicle type in the mod, for example converted John Deere 6M / 7M, no longer lack suspension, the window or the keys.
  • Fix: Tractors whose front axle is a separate physics part. The axle now stays on the wheels and the chassis rises and lowers, so the suspension cylinders extend and retract with the height.
  • Fix: Tractors whose parts have no mass in the XML are no longer treated as light tractors with a pendulum axle.
• V2.0.0.0
  • Suspension window, opened with Left Alt + U: system, mode, height, front-loader stabiliser and live state, including axle load, weight on the front, cylinders, spring, damping and warnings, with a side view of the axle. Settings and panel moved from the game’s menu into the window.
  • Trucks: rear air suspension with levelling (ECAS), up to 3 axles. The ride height stays the same when empty or loaded. Manual height is available for loading docks and coupling, with a return to ride height by itself above 30 km/h. 8×4 tippers and bigger keep their leaf springs. This can be switched off.
  • Levelling only on tractors that have it in real life, based on brand, weight and minimum power, with a default of 120 hp. Small or simple tractors get a swinging pendulum front axle without suspension instead of the game’s soft suspension. Tracked tractors are left alone.
  • Wheel loaders and telehandlers: Ride Control, with boom suspension and accumulator, above 6 km/h and rigid operation below that for precise work. Ctrl + U switches AUTO / OFF.
  • Front loader on tractors: the load really floats with the movement of the arm tip. It can be switched on or off in the window.
  • Firmer damping on the road above 30 km/h, JCB Fastrac rear self-levelling suspension and hydraulic valve sound.
  • Rigid front axles, for example John Deere 7030, move and tilt as one piece.
  • No more shaking on independent suspension, including JD 8R ILS, and no more little hops when switching tractors.
  • Panel warnings: “end stop” and “front too light – add ballast”, plus the name of the tractor’s system. The panel can be switched off. It hides while the window is open and when Zasty HUD is active.
  • Cars, combines and other vehicles are left alone. The shop category is checked.
  • Keys: Ctrl + U for mode, Ctrl + Alt + Up / Down for manual height while held, and Alt + U for the window.
  • Removed: Ctrl + Alt + L and Ctrl + Shift + U, now available in the window.
  • Fix: the default keys were not assigned on a new installation.
  • Default keys:
    • Left Ctrl + U: Suspension mode, or Ride Control on wheel loaders
    • Left Alt + U: Suspension window
    • Left Ctrl + Left Alt + Up / Down arrow: Manual height while held
  • These are the default keys. If one of them is already used by the game or by another mod, go to Options > Controls and set the key you prefer to avoid conflicts.
• V1.1.0.0
  • Big update: every machine now behaves almost like the real one.
  • Tractor classes: automatic levelling only on tractors that have it in real life. Small and simple tractors get a pendulum front axle without suspension.
  • Wheel loaders and telehandlers: Ride Control with boom suspension. The load floats over bumps above 6 km/h, and the arm is rigid below that. Ctrl+Alt+U switches AUTO / OFF, or you can bind your own key.
  • Front loader damping reacts to the tip of the arm and ignores smooth hills. It has its own switch, Ctrl+Alt+L.
  • Road damping is firmer above 30 km/h.
  • JCB Fastrac: self-levelling rear axle.
  • HUD: warnings for end stop and for a front that is too light, with the instruction to add ballast, plus the name of the tractor’s system.
  • Sound: hydraulic valve sound when levelling.
  • Smoother operation: no shaking on the JD 8R ILS and no hops when switching tractors.
  • Settings: new options in the controls menu, all in 25 languages.
  • Tracked tractors are left alone.
