Can't you obtain HyGayd/HyGard low vis in your country? I know Deere has a world wide presence in the agriculture industry and their fluid is exactly what you need as they build a comparative machine to what you have with similar drivelines.
I use their HyGard/HyGard low vis in several wet clutch and hydraulic systems and its very good fluid, its generally regarded as the gold standard in both hydraulic/hydraulic wet clutch systems.
