The aim of the scientific contribution is simulating the load of gear hydraulic pump used in agricultural machinery in laboratory conditions, where the impact of ecological transmission-hydraulic fluid on life limit (flow and efficiency) of gear hydraulic pump GHD1-17R is monitored. Laboratory test equipment was used for the simulation. The equipment was used to perform life limit test of hydraulic pump and to monitor changes in physicochemical ecological energy carriers. The simulation in laboratory conditions took 500 hours. The Vickers test took 100 hours. Transmission-hydraulic fluid MOL Farm NH Ultra was used for simulation. The results were that fluid is appropriate to use in this type of hydraulic pump in agricultural machineries. According to the Vickers test, the fluid is characterized by an increased value of flow and efficiency after 50 working hours, thereby exceeding the specified test values.
