That 50g weight is 12500 with long arm and additional counter weight , thumb. I have same 2 machines. My friend has angle blade, his weight is 13000. Lbs.
I’ve rented the 17G several times, very user friendly little unit. The factory thumb on them is surprisingly strong too. I don’t think they offer many packages but that would be my buy if getting into that size class, bobcat, kubota, tackeuchi and cat are fairly clunky in that size class.
