Scale models of agricultural tools represent original objects. They are also apt to show way the originals were used. The visitors are increasingly interested in the operation of these means of production.

All models we show are operable. The models make it possible for us to show the development of agricultural machines and machines of food production.

Important stages of agricultural development are shown via models. The models made in the model plant of the Professional Museum are shown at our permanent exhibition and exhibitions in other museums of the world. The number of models based on authentic documents and real objects is nearly 200.

We also display the following related to food production:
- tools, not operable models, copies
- scale models
- original objects and segments of operable models
- other necessary units to show development

The number of original technique history segments are of a special interest. The operable segments provide picture of the operation of museum pieces. The segments are the same age as the original objects.
