Typically my production goes like this:
It takes about 7 decent sized trees to make a cord of wood. I have 7 chokers on my skidder, so I pull about 1 cord per twitch. Counting twitches per day gives me how many cords of wood I cut per day. Generally, I cut a twitch every hour, so about 1 cord per hour. That is why I can get a load per day (10 cord), but seldom put in a 10 hour day cutting wood; I just do not have it in me anymore. I am usually done about 2 PM, but I am pretty sick too.
It takes about 10 cord to fill a tri-axle truck, or 15 cords to fill a tractor trailer.
For hardwood logs, it takes about 75 to fill a tri-axle, or with softwood logs, about 125 logs. I typically d not ship logs on a tractor trailer. The log yard is only 7 miles away.
Even then logs can be converted to cords. A thousand board feet of logs equates to about 2 cord of wood.
I typically can cut a load of logs, or a load of firewood/pulp in two days time.
