Historic vs. current: perfection in miniature format
The 1:32 scale model of the Pronto DC has already been available since the Agritechnica 2023. For HORSCH’s 40th anniversary, the historic Terra-Trac will also be available as a detailed miniature model. Behind this model, there is a much more complex process than usual.
Several versions of miniature models of HORSCH machines are available: from Brixi for self-assembly to precise toys of the 1:32 scale models. The detailed replicas of the machines that are used in the field are particularly sought after for the desk or the display cabinet.
Each model carries the innovation and the history of HORSCH and takes part of this tradition directly into the homes of the collectors and technology enthusiasts. To finally end up with as detailed and as realistic as possible 1:32 scale model requires a complex process that ranges from the discussion about the respective machine, the data collection to various prototype stages.
The HORSCH Pronto is a machine of the current product range that is available in a scale of 1:32. On the occasion of the 40th anniversary of HORSCH, miniature model fans soon will be able to purchase the historic Terra-Trac, too. Both machines play a major role in HORSCH’s company history.
Two models with a history
The Terra-Trac was one of the first machines HORSCH built after its foundation in 1984. The three-wheeled tractor was a supplement to the Seed-Exactor and, at that time, contributed significantly to the success of the still young company. In 2002, its production was finally discontinued as the company focussed on other product sectors. Even today, it is considered to be an important milestone in HORSCH’s company history and is a symbol of the clear focus on the requirements of the customers. In 2020, within the scope of a project, apprentices restored one of the first Terra-Tracs that was still owned by a customer. Visitors now can admire this Terra-Trac in the exhibition space at the Sitzenhof.
In contrast, the Pronto is an example of the continuous innovation at HORSCH and has been an integral part of the product range for many years. The Pronto concept is optimised constantly to meet the different requirements of the farmers. The seed drill now is used all over the world.
Challenge data collection
Before models are available for customers, it first has to be clarified which machines are suitable. Attention is paid to the fact that the specific machine and its equipment are interesting for as many markets as possible and thus also for a lot of collectors. After all these details have been clarified, the order is placed at the model maker.
Even though the final product for both the Pronto and the Terra-Trac was a detailed 1:32 scale model, the approach was quite different. While the suggestion for the seed drill came from the markets, it was the model maker that suggested to build the Terra-Trac as a special edition for the 40th company anniversary. The data collection for the historic model was different, too.
For the Pronto model, the manufacturer could provide 3D models, like they are used by the designing engineers, as well as numerous detailed photos. In addition, some more photos were taken on site. The seed cover for example was photographed in open and in closed position to reproduce this in the scale models down to the smallest detail.
The current model is contrasted with the historic one. With regard to the Terra-Trac model, we had to face the same problems as the apprentices during the restoration: There was neither a 3D model nor appropriate detailed photos or other documents. We found leaflets from that time, photos as well as design drawings on paper. So the task was to find colleagues who had been working for HORSCH for many years and could share their memories and experiences from that time.
However, all this data was not sufficient to manufacture a detailed miniature model. Therefore, the manufacturer came to the Sitzenhof and took photos of every single detail of the exhibited Terra-Trac. From these photos, he prepared a 3D model which served as a basis for the rest of the process. According to the manufacturer, this approach reminded him of his early days as a model maker when hardly any data was available in digital form.
Different prototype stages
Once the data collection was completed, the process was the same for both models. First of all, a resin model was produced. This special type of resin is very easy to mould. The resulting model was still colourless and was examined by the people involved at HORSCH. The main focus was on proportions and details as things can still be changed at this stage. This is why it is very important that the model is scrutinised intensively.
The tools and moulds for the production of the actual model are only manufactured after the model has been approved and the required adjustments have been made. The first prototypes which were already HORSCH red were then again examined intensively at HORSCH. Only minor changes can be made in this stage. For the Terra-Trac, for example, the group noticed that the radiator grill did not quite match the original. And the highlight of this scale model also had to be tested: the moving tyres which allow for moving the Terra-Trac easily from A to B. After some final adjustments and the final approval, the production of the miniature models started.
Around 1.5 years pass between the idea for the scale model and its final availability in the HORSCH Shop. To continue to meet the wishes of the collectors, further models of HORSCH machines already are in the planning phase.
