Just purchased a new TYM T-1104 110 HP Tractor and trying to get everything together for the 50 hour maintenance. Most confusing is the requirement for the Front Axle gear oil. Specification is Gear Oil API-GL4 SAE 80W/90 (4.62 gallons). The closest thing I can find is a 75W90 Synthetic Gear Lube. It is a GL-5 made by Sinopec. Tractor Supply also has Traveller 80W-90 GL-5 gear oil that is not synthetic for about the same price. Can't find a GL-4 and not sure it really matters since I doubt there is any yellow metal in the Front Axle or Front Wheel drive gears. I was originally planning to use the Universal Tractor Fluid in the front axle, but that may not be a good idea!
Any and all suggestions would be appreciated.
