The process of hooking up a Vehicle-Dolly-Trailer combo is relatively simple: In the base game, only Trucks have a Fifth Wheel attachment point, which means that all other vehicles need a Dolly to hook up to those trailers. The only purpose of a Dolly is to serve as an adapter or "bridge" between a Vehicle and a Fifth Wheel trailer, when that vehicle is lacking a Fifth Wheel attachment point. It has a Drawbar (Ball) attachment at the front, and therefore cannot be towed by vehicles that lack this specific attachment type, but is otherwise perfectly adequate for its job. On the other hand, a Dolly is far cheaper than buying a Truck, if you do not already own one.įarming Simulator 17 only offers one model of Dolly by default - the Fliegl Dolly EA. The usefulness of this is limited, since Trucks are generally better for the job of pulling massive weights. With a Dolly, your Tractors and other heavy machines will be able to tow massive semi-trailers such as Tippers, Animal Transports, Slurry Tankers, and others. It has no other function or special ability. The Dolly is a simple wheeled metal frame, with a Drawbar attachment point at the front, and a Fifth Wheel attachment point at the rear. In the base game, only Trucks can do this without a Dolly. It allows vehicles to connect to a Fifth Wheel trailer even if they don't have a Fifth Wheel attachment point. A Dolly is a type of Adapter in Farming Simulator 17.
