I want to install a back blade on my 3-point hitch while my front end loader is attached to x728. I left the FEL hydraulic hoses all connected, but set the bucket at the position a little off the ground so it would not drag while using the back blade. I turned the hydraulic cylinder lockout valve fully counterclockwise. When I started the tractor and expected the 3-point hitch to move when I used the hydraulic control stick, the 3-point did not move but the front end loader did move. If I disconnect the hoses for the FEL, will the 3-point now work if I turn the lockout valve cc? if this works how do I keep the FEL bucket from dragging while I use the blade?
