No, none of these will "fit" Not that they couldn't be cobbled on but they are designed for an "F" series tractor where the attachments go on the front of the tractor. also the "front" pto turns the opposite direction on a BX to that of an "F" tractor.
Equipment designed for the BX will have "BX" in the model number.
TractorData.com says that a BX2670 takes either a RCK54 or and RCK60 mower. Are the actual model numbers BXRCK54? Is it the -F## that makes it a front mounted mower?
