How much Is enough?

[0ldhag]

The hydrostatic oil level of 2001 Kubota B2910 is confusing me. I just wrapped up another 300 hr service on it. The manual says to add 3.83 gallons but I remember it reading overfilled last time. So this time, I only put in 3 gallons and it still looks a little high on the dipstick. I did everything by the book... Like I drained the oil from the plugs, swapped out both filters, and cleaned the strainer. Should I be concerned that I put in less oil than the manual recommends? By the way, how does anyone see the oil on that yellow dipstick? It is hard to read. I always have to wipe it on a paper towel just to check the level. Is there a better way to check the level?

Don't overthink it. If it's on the stick, you're good. The book says 3.8 gallons because Kubota engineers assume a 100% drain, which doesn't happen in real life. 3 gallons after a filter/strainer change sounds about right.

Cherenkov is right, those manuals often list the dry fill capacity. If you just did a standard drain and filter change, you're leaving a lot of old oil in the cylinders and hoses.
If the dipstick says it's good after 3 gallons, it's probably correct. Run it for a few minutes to circulate, then check it again. If it's in the safe zone, you're good

Hydrostatic systems usually keep some oil. If the dipstick reads high, it could still be okay. Try shining a flashlight on the dipstick if it's hard to see, or get a clear dipstick adapter to help you read it easier.
