I have this JD690 that I have been using for a year or so to do small projects around the farm. I have noticed by looking at the sight glass that the hydraulic fluid is getting low in the tank. My question is , would it be OK to use tractor/hydraulic fluid in the system? It seems to work in other machines but I am never sure of what John Deere's engineers decided to come up with.

Thanks for your help in advance.

Universal tractor fluid will work fine.

I run a 690B and have owner and shop manuals for it. A Tractor hydraulic fluid that meets the J20C spec is what is called for. Most of the tractor hydraulic fluids that I see meet this spec. There is a metal mesh filter in the bottom of the tank which needs to be cleaned periodically. If I recall, the manual calls for a fluid and filter change required every 500 hours.

Thanks everyone. I thought that the Hydra/Tranny stuff would work OK but your replies put me more at ease.

Today's Featured Article - Fordson Model N: Field Service Operations and Lubrication - by Anthony West. The daily or weekly servicing of any vehicle is of the utmost importance, and in days gone by when our favorite tractors were doing an important and Commercially vital job on the farm, these service operations would make a major difference to the running costs and economy of the farm. This being so, it surprises me to see how many enthusiasts attending rallies, shows etc, seem to be unaware of the importance of this constant attention. Possibly the modern machine with its 6,000 mile or even once ... [Read Article]
