Help with IH 5088 with Sprayer

Danny,

Please review this schematic and note that the outside lever has a smaller splined hole which in turn drives the inside valve. The way they arranged the linkage on the 88 series reversed lever location from valve location.

Ok so I have the same question Todd does. I’m running similar sprayer on a 5088 and 5488. Outside black lever runs  sprayer pump fine and is returned to the right spot. I have flow turned down so it matches the pressure I need. 
 

Now..our question is does keeping another outlet pushed forward/back all the time to supply power to the boom folding box hurt the pump. Ideally I would have constant power to the boom so I could use the joystick on ends and terraces. The block is set up for closed center.

These systems are not load sensing, so that second lever forward does make heat in the system, as it constantly sending even when not using the booms.  Running a loop bybass kit on the boom remote will help with this.  I am running the same setup with my 5488 and a Fast BW with hydraulics sprayer pump.

The 88s are load sensing. IH called it PFC but it is the same thing.

Set your block to open center. Then the oil can circulate and not be dead headed.

Press compensating and load sensing closed center systems are different.  It may of been IH version of load sensing, but different from today's.  See the Fast manual below as it has one sets thing up differently for pressure compensation or load sensing.

Looks to me like whatever literature you posted is referring to an older deere hydraulic system when it is referencing pressure compensated. (30-60 series) On an 88 you would want to use the flow controls to control pump speed- not a restrictor orifice. 
 

88 series definitely use a signal/load sense line.
