Background: The Macaw palm ( Acrocomia aculeata) is a tree native to the Tropical America Forests. This has stood out due its high potential for production of oil biofuels, being an excellent source renewable energy. However, rudimentary way exploring palm, mostly using people labor, it not possible extract maximum economical that this plant can provide. In order use in industrial scale, new strategies high-performance machinery several segments chain should be employed. Results: For that,...

In order to reduce the human efforts during manual harvesting and increase operational capacity quality, mechanization of operation has been significantly increasingly in last few years coffee crops. Therefore, for design machines, physical mechanical properties branch are utmost importance machines project. this way, using an experimental approach, present paper analyzes variability branches. The branches were collected different positions, along orthotropic branch: upper, middle lower...
