Pulled all 3 drain plugs and cleaned both strainers. Manuals states 14.3 quarts. I put in about 14 quarts and she's over flowing out the dip stick tube hole. Didn't realize during a service all the fluid doesn't get drained. Is this common ? I'm gonna drain some fluid and do a fill / check fill /check

There may be drains low on the rear wheel drive system cases??
There are.
Ok thanks. Wanted to make sure I wasn't missing something. My first tractor and hst service. Noob city here.
I should of figured my allison 1000 transmission in my pick up holds 20 quarts according to spec but a service only drains 8.
Automatic transmissions have torque converters which will not drain. Your Kubota has no torque converter so you should be able to drain nearly all of the oil. Do not operate if overfilled.

Was it showing over full after you let it idle for a minute to fill the filter? Operate the hydraulics to purge the air?
Yes I cycled the hydraulics and let it run for about 10-15 minutes. I drained about 4 quarts out and then slowly added some. Not over filled . Final fill amount came about to 12 ish quarts.
