The grassland harvesting chain is augmented with a further combination by this application. The collection and chopping of the swathed hay is child’s play with this Pöttinger brand harvest chopping wagon which is drawn by a Massey Ferguson tractor. The front and rear coupling of the Massey Ferguson hauler is suitable for connection of compatible accessory equipment and trailers with a scale of 1:50. The rubberised material tyres guarantee full ground contact. The Pöttinger Jumbo’s hollow, consisting of robust plastic, has a boot lid which can be opened.
