The badge on the back blade spells it out; ECONOMY... from the pics, it appears to weigh maybe HALF what my Gannon does - plates are thinner, hitch appears to be Cat 1 ONLY (mine has another set of draw clevises for Cat 2) mine is 80" wide and weighs right at 1100 pounds, yours would probably tip the scales at MAYBE 600.
It DOES appear to have a hinged rear blade, can't tell but might have latches at outside corners of the back blade so it can be locked down. This is a GOOD thing, I find I keep mine locked down about 95% of the time (better control of aggressiveness by changing top link length; I put hydraulic top and tilt on my tractor to make this easier)
Weight is your friend with a box blade, but if you get a good deal and don't plan to excavate the world, it's probably as good as any other economy model, maybe better... Steve
Oh, and people claim that the Gannons are NOT quick hitch compatible - I thought so too, til I put the hydraulic top link on - it's close, but can be done.
