There are eight tracks prepared for tests on real surfaces.
The texture is selected to cover different difficulties. Four of
them are on flat surface, which means there are no intentional
slopes made. These tracks are created by flattening the soil by
hand. The other four are with uneven surface. These tracks
are created by shaping the profile with approximately threebigger holes. The maximum height difference on a track is
approximately 100 mm. Three main textures are selected;
sugar beet in soil, sugar beet in soil with weed, sugar beet in
grass. There are also one track on flat soil and one on uneven
soil with weed.
