L3901 HST dipstick question.

[BigBodark]

On the HST dipstick on my 2018 L3901, how much oil is required to go from the bottom mark on the dipstick to the full line?

It may vary a bit by brand and model but I think the difference between the bottom mark and the full mark is uaually about a quart.

I thought that all the L's had sight glasses for the trans level. Where is your dipstick?

My L2501 definitely has a VERY HARD TO SEE sight glass. Wish it did have a dip stick.

The dipstick is in the "transmission hump" halfway between the seat and the dash.

I guess I misread the initial question and answered relative to the engine oil dipstick. My L2501 has a sight glass on the left side just below the clutch. There's a half circle cutout on the metal where you can see the window. When I changed my filters I had to add about a half gallon of fluid to bring it to the halfway mark on the window. I did not check it before changing the filters. Note - I have added John Deere hydraulic fluid dye to the system to facilitate viewing fluid level. Disclaimer - Kubota will not be responsible for any damage caused by the addition of the dye. The mechanic at my local dealer said he checked with Kubota and the dye will cause no harm. It that point I got brave and used the dye.

I have been running the JD dye for ten years;way better to see.

I abrasive blasted the HST dip stick and put in the red JD dye in the fluid on my L3901. Much easier to see the fluid level now.

Why do folks not look at owner/user manuals anymore?

I'll 2nd or 3rd the JD red hydraulic dye. John Deere Hydraulic Oil Dye - MT3668

Half the jar did my L3200 fine. Years later I went to use the remaining half in my new L4060 & it was dried up. L3200 had a sight glass, L4060 has a dipstick. 0 chance of figuring if the sight glass was overfill or undefiled with clear SUDT2. Can figure it out with the dipstick, but it's hard. Get the right light, set the stick on a paper towel, etc.
