I noticed that as well CM. It appears they load the tub, and the machine forms the bricks and lays them on the grass to dry, maybe? Another thing I noticed is the first pic, it's laying the bricks directly behind a track. In the last pic, the chute is off the side of the track laying the bricks. Interesting machine. I'm like you, know nothing about the process. I assume the peat bricks are fuel for burning, maybe?
