The mechanical properties for the threshing mechanism design, distance setting and the size of thrasher for better threshing and less damage to the seeds were used. In this study the mechanical properties of unbroken pods of canola were investigated including failure force, failure strain, failure energy, toughness, and modulus of elasticity planted in three canola varieties in the fields of Aliabad city in Iran including Hyola 50,401, and 420 at the three times of sampling in pre-harvest, harvest and post-harvest in two directions of loading (in the direction of small and medium diameter). Canola varieties had different moisture levels at the same time, and this moisture was measured as a sub factor. The results showed that moisture changes were effective at 5% on deformation, failure strain and failure energy and canola variety changes were effective at 1% on deformation, failure strain and modulus of elasticity. Changes of sampling time were effective at 1% on failure strain and 5% on toughness. And also changes of loading direction was 1% effective on failure force, failure strain and failure energy and toughness and it was 5% effective on modulus elasticity. The mutual effect time and variety on deformation, failure strain and modulus of elasticity was significant at 1%, and with 5% significant on failure energy. The mutual effect of variety and direction on modulus of elasticity was 5% effective.
