Hi,
303 oil is available in all the farm stores. It was replaced by HyGard in the JD dealerships. These days, there is the original HyGard and a thinner variant for some of the current machines. You want the original. But the 303 from the farm stores would be fine.

Final drive lubricant
I have used and believe the service manual allows the use of 80-90 gear oil in final drives and transmission of straight 350 and 350B dry clutch machines. Hydraulic reverser and wet clutch-brakes (350C) requires 303-Hyguard.

Re: final drive
Just working on a 350B I recently purchased. The serial number tag is missing but based on the engine tag and other identifying features it appears to be in the 1972 - '75 era.
I downloaded a 350B manual directly from John Deere, and on Page 34, line 22 in their service section, it says to use "John Deere Type 303 Special Purpose Oil or an equivalent."
I understand that 303 has been replaced by Hygard - but I'm wondering if there is a typo or if I've misunderstood something. Any final drives I've previously worked with (not a lot) run 80-90 weight oil.
What am I missing?

Re: final drive
It is common now to use the new fluids in compartments that used gear oil. Formulation of lubricant have changed greatly over the years. 303 was the start of that conversion with John Deere. Use Hy Gard or a UTHF meeting the John Deere J20C spec. As long as the seals are good you should have no problems.
If you come across any "yellow bucket" oil sold as 303, do not buy or use it. Be sure what you get is labelled as meeting J20C.
