No experience but looking at the Argo web site I have to wonder how they would compare to something like a Polaris or a Deere Gator?  I can't see it being any cheaper to buy (or maintain for that matter).  You have  6 or 8 wheels vs 4. and it will be like driving a skid steer everywhere!

It might be better under certain conditions and that has to factor in your decision. How often do you need to bail off in a creek?

Which one is going to be easier to hop in and out of?  If it's easy to get in and out of, it will be used a lot more than one requiring you climb inside every time.

Which one will be easier to haul your cargo? A dump box is really handy every once in a while.  And a lot easier to clean out than a cargo area that doesn't dump.

As for going down the rows you need to do some measuring.  Also compare ground clearance.

Ask yourself which will retain its value 2-3-10 years down the road?  We have a Kawasaki Mule that will go almost anyplace (if it won't go you'll have trouble walking out) and a Rural King"Chuckwagon"  we use kind of like a utility golf cart.  We keep it out of the field and don't go muddin' with it and it works very well for that use. I know the Mule will bring at least half of what I gave for it and will have some value for quite a while.   I bought the Chuckwagon used for $1400.  It still had a price tag on it for ... I think $5995.  Consider what the Argo will cost and ask yourself honestly what you would give for one just like it 3 years old?

As you can tell I have a prejudice. My opinion is the Argo is a specialty vehicle for a specific use.  I'm just not convinced a farm is it.
