I'm looking for suggestions on a small trailer to pull behind a Yanmar 4x4. the tractor is very small and I would like to find something with a capacity of an average wheelbarow. Using it in the woods where I cant get around with the other tractors. Everything I have looked at so far would never stand up to the load or terrain, even going slowly. The axels or axel supports are too weak. Pulled behind a riding mower maybe, but not for hauling firewood.
