What seemed to be nonsense was the disconnect between a component supplier and a manufacturer regarding fluid viscosity specs. Place contaminated materials in disposable containers and dispose of in a manner consistent with applicable regulations. Where feasible and appropriate, remove contaminated soil. non-combustible absorbent materials or pumping. Just to be clear, I was NOT saying any of your statements are nonsense. Murf Join Date: Dec 1999 Posts: 7233 Toronto Area, Ontario, Canada Pics: 160122 Mark, according to the JD literature, the numbers for the Hy-Gard is remarkably similar to the numbers for the Kubota fluid I listed above, not surprising considering that same page in the document says that the Hy-Gard. 3 of 7 John Deere Hy-Gard Low Vis Transmission/Hydraulic Oil MSDS : 20070. 100 5 0 100 5 0 Wet Clutch Test Hy-Gard JD J2 pec 15 Better Clutch Performance Slow-Cool Fluidity Test Low Temperature Flow Hy-Gard and Low Viscosity Hy-Gard are checked for proper viscosities using the slow-cool fluidity test in addition to industry-standard tests. There is no doubt that the Mobil fluid you have selected will work just fine, but there are many many units running with lowvis without issue, and many of them don't get serviced as they should. John Deere Hy-Gard Transmission and Hydraulic Oil. Deere is a very large company and aren't going to spec a wrong fluid for years with anything, warranty claims would tell them they were wrong and it would be changed if need be. and have had lowvis in them since new, without issue, just changed at 250 hrs. We have one of these units with over 1,000 hrs., and another with over 500 hrs. The way these units get damaged is to not clean the cooling fins/fan area, they clog up with grass clippings and can't keep themselves cool. The 4.4 is the oil capacity for the K70.Īnd if you were to use the JD lowvis you wouldn't have a problem. Of course my JD owners manual says to use JD LO vis.they want to sell me they're oil! I have used Mobil1 15w50 for years in my TT K61 with never a problem, and I expect it to do the same in my TT K70. I'm sure TT would have said the JD Lo Vis would work fine if I had asked, but I was looking for a synthetic oil that would handle the heat of a hydro transmission better than an old spec Dino oil. I didn't say TT stated you MUST use 15w50.those are your words. I couldn't find the 5w50 locally and called TT and they said the Mobil1 15w50 would work fine in my TT K70 Hydrostatic transmission. The 5w50 synthetic is the new TT recommendation.
