My wood is cut at 2 to 3m. I 've got a peeling and mowing machine. Whatever comes in and she doesn't leave the fine sticks, production per hour is not important. It is important that the wood comes out at the top. In most cases the wood is from trees from 8cm to 25cm from the foot to the tip of the wood. Most of the wood is 5cm to 20cm. in60 %. From 20cm to 50cm 30%. Below 8 CM10 %. Thank you for the information and concern.
