To increase efficiency when transporting trailers, use the opportunity of installing the rear hitch. This option allows you to attach another trailer or other device behind the PS trailer.
The most common use is to connect another trailer to the combination of vehicles. This increases the useful weight and volume for one turn. Very often such combination of vehicles are to be seen in Austria or Germany. This design has the advantage of easy disconnecting the whole combination and leaving it in the field, for example, to fill the grain. So one tractor is more versatile and can perform multiple operations at once.
