Tree farm device

(Posted by request)
There is a world interaction upgrade in the Transfert node (liquids)

This makes a working tree farm I assume? What block is between the wool?

That's a steam engine !
The torches are here to prevent fire on the wool
The wood shafts and wooden gearbox are flamables, so you need to be carefull about that too.

You need to add a chest below the woodcutter to store the items.

The woodcutter will automatically cut all connected trees (including yours. Use carpenter's blocks to "isolate" the farm') and replant trees that have their base log at the woodcutter level (won't replant trees higher and lower than it
