I’m trying to find a used 2782b front mount snowblower for my 2013 B2650HSDC (cab model). I’m a little confused on the front quick hitches. I found a Kubota chart from 2015 saying I needed a B2714b quick hitch. I found one online listing for a blower and B2714c hitch that states it came off a B2650 cab model. I also found a local listing with the blower and a b2714a quick hitch that was previously installed on a B3030 cab model. Are all these hitches different as far as length, width, hole spacing etc and fit different tractors or do the different letters just indicate some updates over the years but they all fit the same and would work interchangeably? Are the frames in front the same on the b3030 cab as the b2650 cab model? Thanks In advance to anyone who can provide some insight.
