PTO air compressor?

[pfarber]

Does anyone have any idea if there is a small air compressor I could hook up to the PTO of a G506 or G508?

When I take the hounds up the mountain, I had to air down the tires in the M35. The bonus being that there was service air available to inflate them back up. I also had to air down the GPWs tires to get up a hill... but had to run on basically flat tires till I got home (didn't have the air pump under the seat).

So my idea is to rig up a PTO run air compressor (maybe even a 6V air compressor?) so I can dump the tire PSI without having to worry about running on flat tires on the way home.
