Here are two, old-style, heavy-duty, bobsled building plans featuring the sort of sleds you might have found in New England and the Maritime Provinces of Canada. (In fact you might get lucky and find them still.) These are designed to haul cord wood on the sled frame.
The remainder of this section on Agricultural Implements is about homemade equipment for use with draft animals. These implements are all proven and serviceable. They are easily worked by a single animal weighing 1,000 pounds, and probably a good deal less. Sleds rate high on our homestead. They can be pulled over rough terrain. They do well traversing slopes. Being low to the ground, they are very easy to load up.
