I considered the
BX24 when I was tractor shopping last year.The dealer did not have one on the lot, but gave me a price for the BX with a MMM. I ended up with a
b2620 TLB setup, and I'm very happy. The price, while while higher than the BX, was affordable in my mind and I believe I ended up with much more machine.
I agree that weight is a big issue. The
BX25 only has one more engine HP than my 2620....but my machine is hevier, has larger tires and my engine runs much slower to reach the max HP output than the BX.
I'm not saying the BX is a terrible machine, I think it's very well suited for some things. If I were you though I would at least have a look at the B series. The TLB setup is the same as the BX where the tractor seat serves both tractor and BH, the BH is tucked in nice and tight to the machine unlike many others with add on hoe.
Long story short, if I had it to do over I would buy what I have now (
B2620 TLB) or LARGER. I also wouldn't fool with the MMM on a tractor. For what the decks cost you can buy a REALLY nice dedicated mower and not have to mess with mounting and unmounting the deck on the tractor.
