![]() ![]() for me it's just easier to make one trip and get what i need rather than chance the auto parts place getting a wrong filter and halting the process by another few days. it's as close as any auto parts store is, and the local auto parts places aren't going to have all the filters or the oil need in stock anyways. it's not like i change it that frequently, and when i need it, i usually have to go get filters at the dealer anyways. for my time and money, i have always ended up buying the actual jd oil though. I think that if you have an iso 32 oil suited for hydraulic/hydrostatic/gear applications, then i'd bet it is compatible. there isn't much of a cost difference between regular and low viscosity. that's kind of why i suspect that some of these other oils are equals.ġ: it is a cold weather replacement for original hy-gard.Ģ: it is an oil suitable for hydraulic systems, hydrostatic drives, and gear transmissions.ģ. unless it is like kfc original recipe and the secret ingredients are a well guarded item, i can't imagine there not being an aftermarket equivalent. it would seem that there is a market for it since most aftermarket hydraulic oil brands are $30+ a gallon cheaper. you would think that by now there would be an equivalent aftermarket solution, because so many smaller jd models use it now. i would assume that the entire production line of that tractor did too, so that dates it at least a few years before. I don't know how long the low viscosity hy-gard has been out, but my 770 is a 1998 model and it specified it then. fluidĪn oils wieght rating iso 32, iso 46, iso 68, 5w-20 and such has little to do with the additives that make the oil what it is intended for. I had some HY-GARD on the shelf in the garage that meets the J20D spec, but if I run out, its nice to know that I can use an SAE. I would have serious reservations about using it as a tractor/hyd. According to the Official John Deere service manual for Lawn Tractors LX255,LX266,LX277,LX2 (TM1754), You Can use a SAE 5W or 10W30 Oil (Synthetic or Mineral) or John Deere HY-GARD J20C Oil. ISO 32 fluid may be fine for gear transmissions of a light duty or just a plain hydraulic system. Interesting. Tractor John Deere 4100 HST /410 FEL, R4s. I know first hand that the finals that ran in the gear oil had considerable LESS gear/bearing wear as compaired to the finals that used the THF, with same amount of hours. Joined Messages 5,753 Location central Iowa Tractor. ![]() fluid in them often have large hydraulic driven motors that power a seperate final drive of some sort that is a totally seperate unit itself that takes a gear type oil in the final.ĭepending on the year in IH 1480/1680 combine finals used "hy-tran" IH's tractor hyd fluid or 80w-90 gear oil. Large tracked and other hydrostactic driven machines that use iso 32 hyd. oil SHOULD work in a hydrostatic drive system but, a 1023e has just a little more than just a hydrostatic drive system to operate with one oil.
