Establishing qualitative indexes, energetic and exploatation indexes for harvesting machines to fooder plant and silo.

The experiments were focused on testing fodder harvesting machines in order to establishing qualitative index, energetic and exploitation indexes for these units with Romanian tractors U-445 and U-651M. Researches were done on different fields, fodder, climate and soil slopes, effective realization of experiments and experimental data recording were made using the methodology approved by M.C.T. respecting ASAE and ETAMA norms. The effective productivity for rotary mower GMD-44 and rotary rake GRS-24 with U-445 tractor are bigger then Romanian agricultural machines for fodder plant harvesting. Self loading machine LW-220T Pico and Siloharvesting combine Vicon MH-90S Twin with U-651M tractor eliminate handling operations, a high quality of maize silo, but for Silo combine is recommended to use a tractor with a higher power (up to 80 HP).
