wd hydraulic issues

[Steven-Id]

Hi all, I have a wd that was working just fine while i was mowing some ditch banks with a sickle bar mower. When I got done I lifted the bar up and went back to where I was going to park it and when I stopped I noticed a chattering sound coming from the hydraulic pump and it wouldn't go down.
I have a manual for it but I thought I would ask on here to see if anyone has had this happen before I tear into it. Thanks for any info you can provide.

I'd start by checking the pump settings over. It's possible something came loose and it's a simple fix.

I certainly will check the pump settings I was more concerned with what the chatter could be. Thanks

Chattering sound is the pump running against pressure. For some reason it's not shutting off.

Make sure the Traction Booster linkage isn't disconnected or hanging under the tractor. That can turn-on the pump and it cannot be shut down.

The chattering sound might be normal when it's under pressure. Try working the lever all the way back and forth a few times and tap on valve with hammer with it down. If it still don't go down try plugging in another implement and see what happens.
