mahindra 3710 backhoe issues

[taylormade76]

working all morning. then it felt like it lost pressure when lifting bucket out of hole. it wouldn't lift so I checked for blown lines or any leaks and have found none. fluid is full. if I stay on the controls it will take 5-10 seconds of super slow movement then it kicks on and works normally. until I release controls then have to start all over again and wait 5-10 seconds for it to move or lift.

I am thinking it could be the pressure relief valve.... but I cannot find it and have searched the location on this forum to no success.

any help would be greatly appreciated.

The BH relief valve should be close to the IN port.

Show a picture of the valve.

Do the other functions on the BH work OK.

Maybe you have air in the hyd system.
