The 'usual' setup you see is the 722 with a hyd bucket, and a 711 with a trip bucket.. however.. according to the manuals I have.. both bucket options were available for the 711 and 722. The actual determining feature is the bottom loader support. On the 722, the lower support frame is also the hyd sump, and it has a couple tapped ports.. the lines would have then run to the small crank driven pump, and to a set of spools on the upright loader frame... making it a self contained unit. the 711 relied on external hyds, like from a remote on the tractor.. and the lower frame was not setup to work like a sump. My 660 is setup like it is a 711 loader. That is, the oem 722 spool valve on the upright support is gone ( bracket is there! ), and the loader is using remote valves on my tractor to power it. However.. inspection of my lower support reveals it is the unit that had the sump, as my ports have plugs in them. The spare i bought is a 711.. it has no bracket where the oem spools went.. and it does not have provisions for the internal sump. Now I just have to repair the bucket, fabricate or locate the side and front bracket ( I have the lower one ), and then locate a 'preferably' 8xx/4000 4 cyl gas job to mount it to! Soundguy
