Truckntran,
Are you interested in selling the control valve you have? Sounds like it is a dual spool valve. I'll be looking for one for my 1650. I'd like to have rear ports.
As for the loader part, PF Engineering (pfengineering.com) sells plans for a DIY loader and backhoe for garden tractors. They were actually designed on a Cub. Their site indicates the Cub hydro does, in fact, supply sufficient pressure to run the loader, however, some other posters, who seem knowledgeable, have indicated they don't supply sufficient volume. So an auxiliary hydraulic pump will be needed.
If you're interested in selling that controller valve, shoot me an email.

P.S. I just read your post again. I thought you said the valve had
extra hoses going back to the rear. I guess it's just a single-spool control valve. Oh well.
