Maybe it was Kasco (sp?). Not 100% sure. Anyway - ask your local NH dealer. You can get a quick attach kit. Also need the skid steer bracket for your bucket. I think it is an expensive addition - $1,000 +/- a couple hundred.
Regarding the skid steer attachments - you could run a diverter valve on the FEL hydraulics, but the flow would be pretty low (Grapples & stuff OK, rotating things not). Plan B would be a pump on the PTO (Northern Tools sells them among others) with some hoses to the front - $400 +/-... Plan C is to add rear hydraulics to your machine & plumb them to the front - still have the flow problem.
Keep the 600 lb lift capacity in mind with the skid steer attachments, some are pretty heavy duty.
