The YM2002D is newer than the YM2000/240. It is three cylinder, wet brakes, spin-on hydraulic filter, full dash, etc. The USA YM220 was smaller and has dry brakes, the YM276D was larger and is a power-shift. I can't off the top of my head come up with a USA "sister" tractor to your YM2002D. It shares a good deal of parts with the Japanese YM1802D if that helps any.
