How much UDT does my L4400HST hold?

I just changed the hydraulic oil in my Kubota for the first time. The manual says it hold 10.6 gallons.

I added 7 gallons and looked at the sight glass and it looked empty. I checked it again after I added 8 gallons and then 9 gallons. It still looked empty after I added 10 gallons and 11 gallons so I added 12 gallons and it still looks empty.

There are no leaks and I checked my motor oil to make sure it wasn't going in the crankcase.

I ran it a little and the power steering seems weak and the loader seems like it is going up slower than before. The temperature here is 67 degrees, not cold. I am afraid to run it any longer and I don't know what to do next.

Any ideas?

Is there any way to measure what you've drained out?

It's OK now. After it sat for 15 minutes the sight glass filled up. I didn't know it too so long to fill up. I wonder if that is normal? I had to drain out 7 quarts to get it down to the right level.

Now I will go let my engine warm up and give everything a good try again.

For my B3030, the owners manual says:

IMPORTANT - Do not operate the tractor immediately after changing the transmission fluid.

I always wondered why they state that. Maybe now I know.
