Four wood log farm

Dusty Dude's four wood tree farm, the one Shulkercraft told people to build and the reason most of the traffic here arrived. Slime and honey walls with fence gates strip and shove the trunk into a TNT blast, and it handles oak, spruce, birch and jungle from one build. It is cheap for its output at around 200 building blocks, it has been running since 2021, and builders are still confirming it on current versions.

• From 1.18 a new oak variant with logs sticking out breaks the machine. Move the block that caps big tree growth down one, or fit a sticky piston to raise and lower it between oak and the other woods.
• Never put fewer than three items in the TNT duper's hopper clock. Several builders destroyed the duper and nearly themselves doing it.
• Watch that the redstone dust on the comparator clock never turns into a dot, and check every repeater delay. A missed delay on the second leaf crusher is what broke it for one builder.
• If spruce saplings will not grow, set the rear repeater that drives the back pistons to four ticks.
• The camera turns at 3:31 mid cut, which throws the orientation of everything built after it. The video also never marks out the 16x21 footprint before starting.
• For long AFK runs use oak with an apple in your offhand, though you do not actually get hungry standing still.
