Whissel is working on our site right now so I grabbed some pictures of their lineup. They do large scale underground. http://farm4.static.flickr.com/3140/2971119182_5e937a9144_b.jpg http://farm4.static.flickr.com/3051/2971119494_5ac359be80_b.jpg Various sizes can be found at www.vantagefoto.com if you click the picture then click "all sizes".
Nice machines. We have 2 JD 800C's and a JD850D LC. Really like both of these machines. Have them outfitted with JRB couplers and they make for great mainline machines. Our company does heavy sewer work. We have 5 crews, fun trying to keep all of our machines busy in this economy.
