this is an adjustable wrench mount that fits a kubota rops. this is on the b2620 but probably fits most of the small or mid size kubotas. the steel on my rops is 1.5" x 3". this clamps right on using 1/4"-20 machine screws. this is designed to fit a 12" crescent wrench but a 10" also fits. its great to have it right there for easy access while hooking up attachments. a 12" adjustable fits all the 3pt hitch lock nuts.
