Zetor gearoil

[nigel]

does anyone know what type of gear oil goes in a zetor 5718 also engine oil
15w/40 motor oil and 80w/90 gear oil or 10w/30 multifarm

for the gearcase wich is better? motor oil or gearoil?

What you say is correct: 15w/40 motor oil and either 80w/90 gear oil, or 10w/30 universal tractor oil.

80w/90 gear oil and 10w/30 universal tractor oil are of the same viscosity, but both are measured at a different oil temperature, hence the difference in number.

In Australia, only 80/90 is recomended.
