Feb 13, 2018 · Kubota L4400, Kubota recommends K UDT. Some forums reference Valvoline 3089 (about $120/5gal), or Walmart UDT ($100/gal). However Tractor Supply sells Traveller Premium Universal Tractor Trans/Hydraulic Fluid for $40/5gal.

Nov 1, 2019 · Full Disclosure: I’ve never actually done this in a tractor, but I have experienced it when another vehicle was submerged in a stream-crossing. The hydraulic system fluid (a red H5606 hydraulic oil similar to transmission fluid) became very “pink” or “milky” .

Mar 5, 2023 · It depends where your cylinders are. With your loader on the floor all the cylinders are basically empty - more fluid in the reservoir. If you lift the FEL up and fully dump the bucket, a bunch of fluid will be in the cylinders. I'm pretty sure overfull is fine, there has to be capacity in the reservoir to take the fluid from the cylinders.

May 7, 2019 · I've since learned that the little sight glass used to read the hydraulic fluid level is really sensitive, in that if the tractor isnt perfectly level it can read low or high, and also once the fluid level enters the window, it can quickly go from bottom to the top of the window with seemingly just a few ounces of added fluid.

Oct 19, 2010 · Is there any other hydraulic oil that I could use in my transmission other than Kubota UDT. My local tractor supply store carries Valvoline unitrac tractor hydraulic oil-3098 as well as Valvoline anti-wear hydraulic oil-3015. Would either of these be a sutible substitute? Tractor in question is a L1801DT. Thanks.

Mar 16, 2022 · Was doing some research on using ATF in lieu of tractor hydraulic oil, can't seem to find anything that says that is a bad thing as the weights are the same and trans fluid generally runs a little cooler because of various additives over hydraulic oil.

Feb 5, 2022 · Ha! Of Course! THAT is exactly the right answer, and mystery solved. The earlier thread I referred to had convinced me I was not losing my marbles, it was a flaw in the manual - - not true - - it was a matter of symantics - - NOT "Hydraulic Fluid" - - - "Transmission Fluid" - - all 56 Liters (59.2 US quarts) of it And there was the filling port, right where my mechanic said it …

Nov 27, 2015 · same sump holds all the oil needed for the two or more separate systems. They all run on the same oil. HST, power steering, hydraulic system. One filter is the suction filter for the main hydraulic pump; it's on the suction side of the pump so there is only atmospheric pressure there (about 14.5 psi)-or a little less.

Mar 1, 2023 · According to the service manual, a Kubota L3400 4WD Manual Transmission tractor, should hold 7.3 gallons of UDT fluid. I just drained the 4 ports as described in the service manual, changed the filter, and started refilling with new UDT. Problem is, as I was pouring in the 6th gallon, the oil sight window showed it to be full.
