I have only noticed shorter wheel bases on the SCUT/CUT/UT, but not Ag tractors.
Agree with the previous post on maneuverability as the shorter wheel base will turn sharper. The only downsides are it gives a little choppier ride and requires more ballast when using a FEL. I am sure there are others.

Short wheelbase provides for better maneuverability. Take a look at a skid steer, for example. The old NH Boomers, with their Supersteer, are another good example.
Tractors with longer wheelbases are not as prone to flipping over backwards. This is due to the momentum effect of technically adding more weight further in front of the rear axle. It's partly the same principle behind making rail dragsters about 22-24 ft long rather than just 16ft long. Even still, you will see one of them will occasionally flip over backwards.
- No (or fewer) front weights needed
- Less likely to flip
- More traction (drawbar pull) for the same wt and HP
- Better loader balance
- Look better
Why do they use a short WB? All the reasons mentioned in above replies, I agree they will maneuvor better in tight spaces but anything over 40HP shouldn't be used in areas that tight, just my opinion. Besides, with 4x4 (MFWD) you have a LOT of weight in the front axle so there is little reason to add another 12" of length.
My opinion: The happy homeowners and weekend warriors don't want huge "tractors" for hard work, they want compact do-it-all models. This means high engine HP, short WB, MFWD, Hydro and not for me.
