I bought a BX2370 a little over a month ago, I did not have any regrets about the purchase until I read this.
This is what I know so far about the 80 series:
lower rops
one piece hood design
stay on the tractor to remove the loader
joy stick at your hip
SSL type implement attachment
Pat
Then I thought about it for a little bit, the ROPS does not impact me much as I only have one door it won't fit in now and that door will be getting modified for other reasons (not a door I'd use often anyway)
One peice hood would be nice, but reality is I'm not going to be doing much more than the routine service / fluid change myself anyway, more complex and it will go to the dealer, with the current design it is hard to check coolant levels but otherwise not a big deal for me. Even the routine service I only expect to happen twice a year for my use, I'm not using it for work, but for home chores.
Loader removal from the seat would be nice but I use the loader enough that I don't see taking it off except for when I put on the snow blower. Now if I could keep the blower mount on and have the loader on, it would be a different story.
The joystick at the hip would be real nice, it was one of only 2 thinks I liked more about John Deer when I was looking (the other is the seat fit my rounder shape better), but not enough for more than a few hundred dollars more.
The SSL implement attachment, this one would be really nice. Especially if the snow blower can be attached to it (don't see that happening). It would allow for easier access to attachments like grapple buckets, but I am curious if the loader capacity will increase, as that seems like the bigger constraint.
That is just my opinion. For my situation I'm happy I got the 2370, it is a great little machine.
