Using a special lever, you can turn the front wheels to set the correct tractor driving direction. In order to open the bonnet, just pull the lever in driver’s cabin. Tractor doors may be opened, and passenger seats are adjustable. You will not only assembly the set “from zero” – in process of assembly you’ll understand the structure of tractor and engine operation principle. So, you’ll have a good and interesting time, and, probably, you may become an expert in modelling, since all the models of construction sets are designed basing on real mechanisms which operate without fail.
