An adhesive bonding technology is a prospective bonding technology of diverse materials. For successful practical application, knowledge gained by studying factors that significantly influence mechanical properties of the adhesive bonds are essential. The adhesive bond rise is influenced by an increase of chemical – physical links. The adhesive bonding strengthens its position in a number of agricultural machines and tools. The aim of the experiment is to create the adhesive bond which provides the maximum strength and quality for single combination of the adhesive and adherents, usually at minimum costs. This aim can be reached by describing the process of the hardening and ensuring the optimum adhesive layer. Describing the adhesive bonding process and its factors is essential for companies producing agricultural machinery. From the results of the experiment there is visible a significant fall of the tensile shear strength of the adhesive bond with increasing time needed for the adhesive bond creation. The experiment results also certified the negative influence of the unequal adhesive layer on the strength fall but also a huge dispersion variance of results.
