From all the posts it seems like it depends on where you are going in your life. If you're moving into bigger places, more land, more heavy-duty projects, more animals, more more more, then it's probably a progression to bigger. If, on the other hand, you have arrived at that place in your life where you want to be, most or all of the big projects are done, and it is simply a matter of maintenance (and sitting back and enjoying actually being at the place you want to be), then downsizing, or at least maintaining a given tractor size probably makes sense.
As for me, my
B7800 appears, after less than a year of use, to be just the right size for where I am. Over the past nine years I went from a 50 x 70 suburban lot (no tractor) to a 3 acre rural suburban lot (used
B1750) to a 60 acre rural "farm" (new
B7800). If I ever get into livestock in a big way and convert the cornfield into pasture, I might need to scale up again, but for now I seem to be in the sweet spot WRT size and power. The little 1750 was great, but out of its league on this property. Any bigger and I probably would have trouble mowing my lawn. Henro, I sometimes wonder if I would have preferred the added bells and whistles of the 2910, but the size would still be the same.
Speaking of bells and whistles, I do plan to add some enhancements this year. I covet a Top and Tilt, and a set of Pat's Easy Changers (or some other quick hitch device) would be nice. The adjustability of the 3PH on the 2910 is probably the only thing I miss on the 7800. Hopefully, the QH will address that issue.
But, having a little brother for the 7800 like SOMEONE else, sure is enticing. /forums/images/graemlins/smile.gif

p.s. What is most impressive to me in reading all these posts is the amount of research and analysis that TBN users obviously put into making decisions about tractors, attachments, modifications, etc. There's a lot of brain power chugging away out there.
