Kubota B21 - Lost Hydraulics

[Whiety]

Just changed my crankcase oil and filter, and changed both hydraulic filters and strained the UDT back into the holding tank and now I have a strange noise coming from my transmission area and no hydraulics???

Comments?

Kubota B21 Backhoe - 2005. Never had a problem before.

Check the level and allow the machine to idol long enough to remove the air from the system before trying to move it.

Yep, make sure level is good and let it idle a bit. Hopefully that will help the hydraulics to be found

Nope.......let it sit for 20 minutes. Same sound just very weak hesitant jerking hydraulics. The sound seems to be coming from my hydraulic pump and is squealing in what sound like keeping pace with the engine.

Not happy right now.

The only thing that I did not mention above is that it developed a high pitched pinging sound last week when I was loading some busted up concrete into a dump. I thought it was vibration and that made me look at the oil change and date and I saw that it was overdue so that is what I did yesterday.

I have had this tractor since 2009 and it has never given me trouble outside of a stupid safety switch.

I am at a loss right now.

OK............got it fixed......it was a partially clogged front Hydro filter. Operates as she did before!!

Thanks for all of your help!!
