The objective of this work was to evaluate the technical efficiency of the self-propelled harvester with vibrating rods in conilon coffee plantations (Coffea canephora) and its influence on harvest costs. The tests were carried out in commercial fields, with a spacing of 3.50 x 0.50 m. In the tests, the harvest speed (1.0; 1.6 and 2.0 km h-1), the vibration frequency (700, 800 and 900 rpm) and the number of har...
