Hydraulics drifting.

[Danny bubba]

Hydraulics stopped lifting my hay rake. Drained the hydraulics and changed the sump filter. Refilled the hydro reservoir and now the hydraulics will lift the rake but it slowly bleeds off so I am constantly having to adjust it with the control lever to keep it up. What would be the first thing to look at? It never did this before it stopped lifting the rake what I mean is it never bled off like it does now??? Anyone I would appreciate your input!!!!!!!!

Valve leaking or cyl seals.

Can you still get relief pressure?

How many times have you cycled (raised and lowed) the wheels fully?

Might still have air in the system

I can't answer that yet on the relief pressure I havnt been back out to the field I took the complaint from a worker by phone I have to go put my hands on it so I will be able to tell you more after I see it myself. Thanks guys for the info. and I will get back to you some time tomorrow after I have had the time to look at it myself. Thanks again!!!!!!!!!!!!!!!!

I'm hoping it is air in the system since it wasn't there before we changed the filter. I have to go lay hands on the tractor tomorrow personally I have had a worker telling me what is going on over the phone so I will look at it tomorrow and maybe have more information. Thanks a bunch for your help!!!!!!!!!
