Backhoe backhoe wont move

[irwin]

another question???

backhoe seems weak, . where is the pressure adjustment on the JD 7 backhoe? I have 2400 psi coming from the tractor,, thanks bd

How weak? Will it pick up several hundred pounds? If you curl the bucket and place it on the ground then, with slight down pressure on the boom, uncurl the bucket carefully..does it pick up the back of the tractor? Does the relieve valve do it's job at the right pressure? Do you have a service manual? How much experience do you have with small backhoes?

Might be time to replace hydraulic fluid and filters. There are ways to test hydraulic pressures.

bucket wont uncurl all the way
fluid and filter r new
i am going to check the pressure going to the bucket or boom, just wondered where the adjustment for the hoe is,, tractor pressure should be good with 2400 psi .
no service manual.. is there a place to put a gauge on the valve chest?

I turned it all the way in clock wise and then backed it about half way out and eveything went too normal /QUOTE]

Close the valve.
