will this work in the diff and transmission of my 240 farmall tractor

Asked by: seme
Technically, SuperTrac 303 is made for these older tractor applications where most of the components feed out of the sump. 303 has very good demulsibility properties as well which are needed with the seals used in older equipment. The downside is that 303 is a SAE 20 fluid. According to the manufacturer's research on late model Internationals, Hy-Tran or comparable fluids (which includes Super Trac 303) are recommended by the manufacturer, but most owners prefer to run a heavier gear oil in the transmission/differentials. SAE 80 and above. This is a big difference in thickness of fluids. The heavier fluid will provide more wear protection, but will not work as well in cold weather. Thicker fluid will also help stop any small seal leaks that the lighter fluid may be seeping through. With all this said, we would recommend the Traveller’s 80W-90 GL-5 gear oil for maximum protection. If cost is of importance, the 303 does meet the specification called for by the manufacturer and will provide the necessary protection. If using a lighter weight fluid, we would possibly look at changing the fluid sooner than if going with a heavy weight gear oil.

Will it work in a John Deere 1030 tractor ?

Asked by: Paul 69
According to the vendor: "The fluid specification range of this fluid ranges between ISO 40 to 68 with anti-wear additives at levels often found in hydraulic fluids manufactured before 1979. Please consult your equipment owner’s manual to see if this fluid fits your requirement.”
