Can you post a picture of the plow dataplate? I dont get any results for a model "2034" attatchemnt, I do get some for the B2034.
Per Kubota Tractor Corporation - Parts List (search for B2034 and click on the "local options" link) B2034 is a plow mount subframe which fits the following tractors: B1750D, B1750E, B1750HST-D, B1750HST-E, B5200D, B5200E, B6200D, B6200E, B6200HSTD, B6200HSTE, B7100HST-D NEW TYPE >=S / N60164, B7200D, B7200E, B7200HSTD and B7200HSTE (the D on the end of a model indicates the 4wd variant and the E indicates the 2wd variant).
If that is correct, it should fit your B7200 HST 4WD.
