Not to start a paint war here, but your comment about the
BX23 doing "twice as good" leads me to believe you've never worked with a 455. I tested a BX2300 when I bought my 455, and I am not sure I agree with you at all. At least as far as mowing goes, I think the 455 cuts faster and with equal or more power. Once you equip a 455 with 3pt hitch and PTO, 4wd is the only advantage the BX series has. If I had been buying new, I probably would have gone with a BX2300 (have hoe and loader on my CUT) over a new John Deere X5XX or X7XX, but finding a used 455 for less than half what I would have spent on the BX made it a "no-brainer".
