Zetor 5245 where the implement lift not working

[simonbrodin]

I do only have one pump, did change that one because the front implement didn't work, now that works but not the implement in the back, I'll check the knob tomorrow thanks for you helping

If you have flow to the back, you should still be able to raise the lift arms and cause the relief to sound.

However if the knob is tight to the right, you will not have any down action.

Do you have a lever or switch to block flow to the rear?

Do you have remote valves?
