- John Deere 790 with loader LS xr3140h also with loader plus a cab
I did the 50hr. Service not That long ago on my XR 3140h. When I did the hydro and hydraulic filters I noticed the fluid looked and smelled very much like regular iso 32 or 46. Odd it seemed to me at the time, because iso fluid has not the additives like a quality tractor/hydraulic fluid for brake chatter, or the EP ratings.
Then it was pointed out to me, iso 46 is what LS uses in this model of tractor for trans/hydraulic fluid....
I know there is different additives between the oils, but just reg. ISO hydraulic fluid for a common sump for trans and hydraulic instead of a tractor trans/hydraulic seems lacking with wet brakes on the LS and potentially higher pressures and temps with a hydrostatic Tractor tranny.... Especially when some other hydrostatic systems call for a 10w-30 oil
What is your thought of ISO hydro fluid for a common tractor sump oil?
