Can a 6080 run a White planter blower?

I would think they would but you will probably need to add a 'power-beyond' valve. You'll need someone smarter than me to help with that. 

Yes, but No, don't try.  You need a PTO pump.  I run a blower on our 185 for replants etc by taking off the the traction booster outlet on the pump and plumbing it into the blower direct with a 2500 psi safety dump. The motor return goes to sump. Works fine just have to keep the rpm up above 1600.  So it doesn't take a lot of gpm. The 6080 is an open center system that has 2 sections - one for the power steering with a pressure relief dumping to sump = you don't want to pressure the return from the steering motor. The other goes to the remotes. You can not Tee into this and unless you devise a flow control , well it gets complicated. A power beyond is used to power the 3 pt and attaching here will kill the blower when the lift/remote is actuated. Get the PTO pump. In the past I ordered a generic pump with way too much gpm and it heated the system even using a L2 gleaner for reservoir and cooler so spend the $ and get the OEM pump with reservoir and remember it floats on the pto shaft - do not bolt it to the drawbar.   

Agree with pto pump choice.
I’m currently configuring a 540 pto JD planter hydraulic pump to run a Kinze 3000 vac & Vset meters. Anyway I see lots of White Air planters using this exact same pump. From your comment/question your White planter’s hydraulics are plumbed for tractor & so maybe no pto pump?? Which is it?
Don’t believe Deere mfg it, but maybe mfg’d by Command? Its housing is what I would refer to as a “half-moon” shape. It is an aluminum housing reservoir/pump combination. From searching the internet & talking to owners/operatorsof such pto pumps it appears these pumps produce 5-6gpm volume. Believe the JD(7200s) & Kinze(3000s) use ~ 3gpm for their motors. I don’t know about White planter blowers volume.
It’s aluminum housing dissipates some fluid heat buildup, but an in-line radiator(12”x12”?) with no fan is all that is needed to help cool hydraulic fluid. Hydraulic fluid recommendation is 10w(AW32). Most if not all White planter’s blower housings usually incorporate a cooling radiator near their intake to draw air over hyd fluid radiator~ good design.
If this JD pto pump is of no avail, think the older IH Cyclone planters pto pumps will suffice? Or if no other options, a older Chevy c10/c20, GM, Ford, Dodge power steering pump can also make do…?
