Optimization of Suction Channel System on Vacuum-Type Soybean Seed Metering System Powered by Hand Tractor

Jurnal Teknik Pertanian Lampung (Journal of Agricultural Engineering)
A vacuum-type soybean seeder powered by hand tractor for Indonesia’s local soybean has been developed to overcome soybean low productivity. The developed machine still has a weakness in the context of the suction channel system. This research was conducted to optimize the suction channel system efficiency, suction performance for bigger type of seed ...
