I am a trail steward for a mountain bike club in the Dallas area, we needed to get 3 land bridges back over a mile into the trail. Each is 16ft long and 3 ft wide. So I used a 1980 CT 110 as a mule.
Can't see the full size pics, but I get the idea. Pretty cool, better than dragging the stuff yourself, plus a 2-wheeled tractor is probably easier to get to rough places.
The trail has some spots about 31 inches wide, the bridges was 30, not much else would have worked but man power, and why use that when ya got a strong honda
