techincally yes.. but there's more to it than a simple yes..
1, you can chaint he 3pt down, engage the pto and tap the pressure test port with an orb fitting, runt hat line to a OC ( logsplitter? ) DA valve, with it's return line dumping into the trans sump. then use da functions on it's ports. PTO provides hyd flow and pressure ( 1500-1700 psi up to 2.85 gpm ).. but is not live... so if foot is on the clutch, or pto not spinning.. it dies.
now.. a couple members here make add on engine pumps that guve you either more 3pt flow, or live 3pt with no pto involvement.. or the option of a remote ( and/or really )
TOH and Zane are the people that make these kits..
still there are other engine mounte dpump options you could fab, depending on if you had a loader or not..e tc.
