I formerly tried to haul firewood up from the woods in my little Gravely dump cart, drawn by one of the Gravely tractors. It was rough going. The Gravely is not powerful enough and the small wheels on the dump cart were unsatisfactory for the job.
A neighbor told me about a bigger and better trailer for sale nearby. I went down and got it. It is shown in this picture.
I attach this to the Ford 8n. I can haul a very substantial load of logs on this trailer. It's a beast.
You may be wondering about the triangular structure on the front of the trailer. That is a streamlined fairing, designed to reduce wind resistance on high speed runs.
