Had an old smaller  great bend 651 3pt mounted on my old L2850 very handy, it was self contained meaning you hooked the hydro pump on the pto shaft, if I ever needed another 3pt bh I'd probably look for the same setup for hydraulics.  Never needed a thumb I curled the bucket into the stick when I needed to hold something,  I do see the advantages of a hydraulic thumb though.  Being my first tractor and BH, some would probably consider my usage as abuse.  It didn't have a subframe for the BH it did have a subframe for the loader  running all the way back to the rear axle though.  Still have and use  the L2850, and sold the BH when I bought a mini x both tractor and BH  are/were  in good operating condition.
