Nowadays, conservation tillage technologies play an important role in plant production all around the world. The Czech Republic conditions are not an exception. Conservation technologies application brings some risks. To minimise these risks, it is necessary to ensure distribution of straw, husk and other plant remains as evenly as possible. Crushing and distribution of straw appears to be no problem during harvest, when modern types of combine harvesters are used. Unfortunately, the distribution of husk and other small remains are non-uniform very often. Similar situation is, if axial combine harvesters Case IH are exploited. If a design change realised by protraction of distributor's driving shaft length to 200 mm is applied, then the distribution of husk and other small remains is much better, too. The distribution of straw is good in the same time as well. If a design change realised by additional distributing metal sheet vane mounted on a lower side of plate and flicker straw, then the distribution of husk and small remains is better as well, but not so much. Problems with crushed straw distribution can be expected in a field with a higher crop yield.
Key-words: agricultural engineering; straw crushing; conservation tillage; husk distribution.
