Any suggestions?

Thanks

Pretty odd since down pressure comes from the same source as "up" pressure.
Lets try to refine these symptoms a bit.
Do you have down pressure with the hoe connected?

Yes I do,

it is a Woods BH7500 I took it off to change oil. Them there was no down pressure.
Today I put the hoe back on and everything works.
Thing is I don't want the hoe on right now..

It could be as simple as your perception or a weight issue, as with the BH off it's now front heavy!

there is NO down pressure, I have to turn off the tractor to get the bucket down.

did you connect the hose together after removing the bh?

Now we have something that makes more sense. That is not simply no down pressure - it is no down altogether. Sounds like the line from the loader is blocked. Double check all hose connections. Something is not getting reconnected when you remove the backhoe - most likely the quick connects on the backhoe line.

So I should connect the 2 lines from the hoe together?

Yes!!! When you leave them disconnected you are blocking the flow of oil back to the tractor and dead heading the pump. If you run the engine like that for any extended time you risk damage to the pump. The manual for the backhoe should make that crystal clear.

I don't see where the backhoe manual states this?

so I can understand this
The 2 hoses going to the hoe are providing a constant 2000 psi or so at all times?

So I need to complete the loop if the hoe is off?

Also there s a valve under the tractor that the manual says should be changed from one state to another
IE turn from 90 degrees to 180 degrees if an implement is not attached , does this relieve the pressure?

 

[zpq]

Sorry 90 degrees to 120

The pump supplies a constant flow. It comes out the hydraulic block on the side of the tractor, through the loader valve, on to the back hoe, through that valve, and then returns to the tractor. That circuit has to be complete at all times for the hydraulics to work. The pressure in that circuit varies with load and when all of the implement valves are in neutral is quite low..

The valve under the seat disconnects the implement loop and redirects flow from the implement loop back to the tractor. As long as you have ANY implement attached the valve under the seat should not be moved. Your loader counts as an implement and will not work if you move that valve. Same for the backhoe

Just connect the backhoe hoses together and all should work just fine. I could not find a manual for the BH7500 but here is the pertinent section from the BH75 manual.

It works now. I guess the 1st time I tried connecting hoses it was not on all the way.

Thanks to everyone for your help.
