I was going to recommend a L2502. Used to be called a 2501. No regen, no exhuast filter. The regen on my 3901 drives me NUTS. Would have bought the 2501 and put a turbo on it in hindsite (see orangetractortalks.com). My opinion is the 2502 is more tractor for almost the same money. No mid PTO though, so no belly mower if thats your thing. If so, you made the right choice on the BX
