In 1855, Hussey attended another world's fair, the International Exposition in Paris. This and the 1856 Agricultural Congress, also in Paris, provided opportunities to demonstrate Hussey's reaper in France. Hussey achieved a "gratifying measure of success," but was unable to win the top awards, which went to McCormick. In 1857, a Hussey machine made in Vienna was defeated by a McCormick machine in a field trial in heavy rye near Budapest.
