A Farming Simulator 22 mod that locks the joints of double trailers so they stay straight. You can finally reverse with a dolly, a turntable drawbar trailer or a trailer train.
- One key (ALT + L) locks or unlocks the whole trailer chain behind your vehicle
- Only the side-to-side turning is locked, so trailers still follow bumps and slopes
- The hitch on your tractor always stays free, so you steer the train from there
- A "Trailer lock: ON" text shows on screen while it's locked
- A trailer you unhook unlocks automatically
- Works in multiplayer (the server applies the lock)
| Setup | Locked | Stays free |
|---|---|---|
| Tractor + turntable drawbar trailer | Turntable (front axle) | Drawbar on the tractor hitch |
| Tractor + dolly + semi-trailer | Dolly → semi-trailer | Tractor → dolly |
| Tractor + trailer + trailer | Trailer → trailer, plus any turntables | Tractor → first trailer |
