I bought a
B7800 April '07.
I directly compared these 2 models when I was buying. The dealer offered both Bota and JD although the JD Ag Line was obviously their bread and butter. I had an idea of "size" needed for my place and a budget cap of $20K for tractor, mower, and loader. I'd had a 6' ZTR and really wanted to stay with that size of a deck since I mow over 5 acres with the rest being woods. With all the obstacles I wanted a MMM deck as about 1.5 acres is semi wooded and the remaining 3.5 acres is open. A BX or 2305 could have worked except for ground clearance and sacrificing deck size. I chose the
B7800 as it seemed "beefy" and offered the 72" driver over deck. The extra hp didn't hurt it either. I've been very happy with it's 35 hrs of service so far although I've had a few minor issues.
You really need to decide what tasks you have. I'm about 75% mowing - 20% landscaping - and 5% snow removal.
3pt Hitch features - Position Control wasn't that important to me since I'd be doing very little blading and no field plowing etc. I solved the cheaper linkage problems by adding a quick hitch from Harbor Freight. I leave it on all the time. My most used 3pt implement is the 600lb concrete filled drum for ballast.
I did really like the sloped hood and quick attach loader buckets available with the 2320 and the 200CX combo, but the $1000 price diff, extra HP, and bigger deck sold me on the
B7800.
