Hi all, long-time listener, first-time caller. I have a Kubota BX2350 with a mid-mount mower and rear PTO-driven bagger (both Kubota brand). The issue is that when I go to lower the deck, the rear hitch lowers as well, but will only go down an inch or 2 before the solid upper bar stops its from dropping further (preventing the deck from lowering to the ground). Isn't the deck supposed to be able to operate independently from the rear hitch? Thanks in advance.
