Abstract

In mountain regions due to the high slopes, the coffee harvest is carried out manually, generating higher production costs. An alternative to reducing these costs is to use portable breakers. The objective of this work was to evaluate the efficiency of portable coffee breakers in coffee harvesting. The experiment was carried out in a field of Catucaí Amarelo 24/137, 3.5 years old. In the study, six types of breakers were tested, in addition to an extra treatment, the experiment was delineated in randomized blocks with four replicates. The number of broken coffee, remaining coffee, number of broken branches that fell on the melting cloth, number of primary and secondary branches present in the plants and defoliation were evaluated. The commercial bruising Brudden promoted a greater amount of broken branches fallen in the cloth of derrick. Regarding the defoliation, it was observed that the Brudden melt promoted the highest values, followed by commercial brands AGS Dupla, Nakashi and Sthil WR9. The treatments Sthil WR6 / 2 and WR6, and Sthil associated to the rubber extensors obtained the lowest values of defoliation. Brudden was also the one that promoted the largest amount of broken branches accounted for in the plant. Based on that, results showed that harvest process using portable milling machines has high harvesting efficiency.

Key words: Operational efficiency, defoliation, Coffea arabica.
