caterpillar941b, that thing is really cool, i would love to see this thing work! i have pictures of this thing that i found googling around, looking for "track skidders", i have to wonder if this would catch on now with the price and availability of cat 527's the way they are.. the production per turn i would think would be 2x's that of the 527 for what a guy could presume would be about the same cost per hour, i think it would fit in the niche of clearcut to steep for wheels, to flat for yarder, to long for shoveling say 400 ft+ average skid? what do others think?............................theironoracle
