There are 2 of us with 2 sets of equipment.  Both have the same light footprint 'stand on' mini skid steers. Long wide tracks. Very powerful, top or near top performance for the size. These machines are not the budget variety they are top of the line, quite new and very well maintained. One is setup for holes and is on a flat deck van. This makes for a very quick unload and loading. Easy to park in congested area's.  The other is rigged for screw piles but can do holes as well. This is carried on a small trailer behind a pickup truck. Very versatile.
