This category has a few useful information about trailers that are used for transporting goods. Some of them can't be purchased. They can be found on the map and you can't sell them (transportation trailer for wool and milk).
You can choose from four tipper models. Their only difference is capacity. However, you must remember that bigger wagon generates more burden and because of that a vehicle will move slower. The biggest one, Fliegl ASS 298, requires an "adapter" - Fliegl Dolly EA hitch or you must use a tractor. All tippers unload from behind in a place where you can empty them, in a warehouse or in a shop. You can't combine tippers.
If you want to transport your animals to and from their pens you must get Joskin Betimax RDS 7500 trailer. It can transport up to 10 animals (8 cows). In order to buy animals you must drive with your trailer and stop next to a shop and select action icon. If you want to load/unload them next to their pen you must get to an animal icon in front of a pen and press action button.
Fliegl Low Loader is a type of transport trailer that is used to transport big and slow vehicles to places that are far away - mainly forestry machinery and combines. This vehicle is completely optional. However, it requires Fliegl Dolly EA adapter if your vehicle doesn't have a hitch. After attaching a trailer to a transporter press the action button to lower a ramp. After that you can drive your vehicle on it.
