This is the one that controls the (front) bucket lift and tilt. It is located just to the right of the engine flywheel, below the fuel tank. It is leaking on the rear side, probably from the spool covers, but I haven't got in there enough yet to be sure. What I am hearing is that valve is very difficult to work on in there, I will need a variety swivels, extenders, crow-foots, luck, and cussing! Does anyone have a good diagram of that valve's construction, like an IPB or cut-away, so that I can be best prepared as I fumble around in there to remove the spool covers and spools?
