2WD with a loader is still better than no loader at all. In most instances if you get stuck, you can drop the loaded bucket and "Crab" your way out. If you've never had 4WD on a tractor you wont miss this feature...If you have then you'll be somewhat dissapointed.
Two red flags immediately come to mind....Recondtioned and Bulldog indicate this is an imported machine from Vietnam and NOT Japan. I urge you to do your homework and search carefully before you part with your hard earned money.
Rollbar? Is it an OSHA approved ROPS? Ask to see the certification. If not, it may be more dangerous than not having one. See THIS.
Ask the seller where you will get loader parts (and for a manual, etc.) We get calls for loader parts for bulldog and v-tech, both used on the vn recons, and we have no idea where to get the parts. Apparently the sellers of them do not either.
The front axle on the 2wd is significantly lighter then on the 4wd....bear that in mind.
