600 hydraulics

[Anonymous-0]

Hey Guys, I need help with my 600 lift problems.THE LIFT ARMS RAISED WITH NO LOAD ON THEM BUT HICUPPED.THEY WOULD NOT RAISE WITH A BUSHHOG ON THEM.
The lift will only raise under load if, I lift the draft lever under the seat all the way up and wire it in that position. I had the top unit rebuilt.new fluid. I WAS TOLD TO REPLACE THE RELIEF VALVE. I have a new one but have not replaced it yet. Can anyone help me?

Well for something like a brush hog it should be in that position, but you shouldn't have to wire it there. So you have a problem with that part of the lift. I can't tell you how to fix it but know it should sit in the up position on its own. On my 841 I have never used it any other way but I also don't use the tractor for plowing so I don't need to use the draft position which by the way is when its down
