Just as a side note, depending on the scope and scale of the work you are doing, and your typical accessibility, taken out a section of fence and re-installing it is pretty easy and inexpensive. If you're moving a lot of material, skid steers are the way to go.
I have used both the mini-bobcat (dingo) and full size skid steers and the both have their uses, just depends on the application. But if you are spending a lot of time moving 1/4 cy of topsoil at a time, just to get through a gate, then pull out the post and use the skid steer.
Another manufacturer to look at that was at the PLANET trade show was
Boxer Equipment - Big Power in All Places. Very cool equipment and also an optional trailer that towed the machine and several of the most popular components, pretty powerful too.
