Hey guys, new poster here-
Did the hydraulic fluid change yesterday on my Kubota b21. Did every step as per the manual (replaced hyd filter, hst filter, cleaned strainer for tank inlet) refilled with Kubota premium UDT and started tractor.
I left the machine to run for 10 mins and jumped on to move it and now have no hydraulic functions/power steering....
Assuming I lost prime in the pump, I cracked some fittings on the loader cylinders to try and purge air but no luck. Moved the wheel back and forth- no luck
Hoping i am not the only one who has had this problem with a tractor like this and that you fine Kubota experts here can direct me to my next step(s)

The pump should not need priming. May need to drive it and operate the controls a little longer to work any air out.

Check the fluid level again.

Thanks for the reply- Any risk of pump cavitation by running it?

Does the yellow dipstick under the seat have oil on it when you pull it out? The thing takes like 7 gallons of UDT I think.
