Hi Converse. You will probably find this is for one of the many types of GMC mower from the early 2000's
They arent a awful mower, provided you get one with the dual swing back blades (they take honda blades).
The catcher flaps are quite weak - often end up cracked
With a 3.75 or 4 hp briggs on them, they are a good mower to use for when you don't want to risk buggering up a good victa - I have a old 1993 3.5 Briggs Masport and a 4 blade Viking mower with quattro 40 for those purposes
