REDSTONEPEDIA › Farms › Iron farm
Middle-ground iron farm (the most iron for an evening's build)
430 iron an hour · 2,562 blocks · 0.17 an hour per block · 333 iron to build · villager carousel: twelve villagers ride minecarts past one golem station, a gate at every stop
Villagers scared by a zombie summon iron golems; the farm kills them and collects their iron in a chest.
Twelve villagers ride minecarts on three loops; 57,319 blocks of room (43×31×43). Four three-villager modules side by side make 426 iron an hour each, at 28.0 build minutes each. Nether quartz: 56; iron: 333. Its storage holds 5 hours of iron.

Try it
Press play to watch it work: the villagers sleep at night and panic at the zombie by day, golems spawn and die, and the hoppers carry their iron to the chest; the top right counts the game's time, the golems and the iron. The magenta floor is where a golem can spawn, seen through the blocks (Spawn spots hides it). The chest tagged OUT, under the last hopper, collects the iron. In the game, build it and wait near it.
How this design does it: Carousel: 4 groups of 3 villagers, one per minecart, on 3 concentric loops (inner side 28); the golem's fall through a tripwire releases every cart at once to its next stop; the north stops are the station over the pad.

The .litematic opens in Litematica (Minecraft 26.3): every block of the design in one region. The text file is the same build written as plain text, block by block.
Pour in the water and the lava (4 bucketfuls) where the view shows them. Leave open sky above its daylight detectors: they are its dusk clock.

Details: how it works, measurements and properties
In depth
villagers scared by a zombie summon iron golems; the farm kills them and collects their iron in a chest
How to try it
Press play to run the farm. The villagers sleep in their beds at night and panic at the zombie by day, golems spawn, fall and die in the lava, and the hoppers carry their iron and poppies to the chest. The chest tagged OUT, under the last hopper, collects the iron. The top right shows the game's time, the golems so far and the iron in the chest; the speed menu plays it faster or slower. Drag to look around, pinch or scroll to zoom.
Measurements
On Hard, through rain, thunder and lightning.
| metric | value | what it means |
|---|---|---|
| iron per hour per block | 0.17 | iron ingots an hour for each block you place |
| iron per hour | 430 | iron ingots an hour |
| iron range | 95% 420-441 | the range its rate falls in, 95% sure |
| golems per hour | 108.6 | iron golems an hour |
| seconds per golem | 33.1 | the time between two golems |
| share of ceiling | 90% | how close it comes to the game's limit: one golem every 30 seconds for each group of villagers |
| modules | 1 | groups of villagers that each summon golems on their own |
| iron per hour per module | 430 | iron ingots an hour for each group of villagers |
| kill | 20.8 s | how long a golem lives before the farm kills it, at the longest |
| kill tail | the longest 54.95 s: no golem outlived 1 min in 1,448 golems (95% bound 0.21% a golem) | |
| golems at the zombie | 0 of 1,448 golems targeted the farm's zombie | |
| riding | 40 middays, 0 with a villager not riding (the fewest 12 of 12); 1,448 of 1,448 golems summoned by riders, 0 by villagers off their carts | |
| bill | 333 iron, 56 quartz, 0 villagers, 12 beds, 1 zombie | what it costs in survival: iron (hoppers, the bucket and every tool you need), quartz, villagers, beds |
| payback | 46 min | how long the farm takes to make back the iron it cost |
| build time | 211 min at middle prices (2,549 placed, 0 dug, 1 lava trips, 0 villagers moved) | about how long the build takes: placing and digging its blocks, fetching the lava, moving the villagers in |
| time to an iron kit | 214 min (the build | about how long from starting the build to a full set of iron armour (24 iron), its own iron counted |
| then | 24 iron at the card's rate | |
| then | the trip to the chest) | |
| build minutes | 211.1 | |
| t kit minutes | 214.4 | |
| collecting | 0 s per trip to the chest (2 x its depth, 0 layers | |
| at | the access's speed) | |
| iron per hour sleeping | 786 | |
| volume per module | 57,319 | |
| entities alive | 26.7 | |
| entities peak | 29 | |
| tools | bucket 3 + shears 2 + iron pickaxe 3 | the tools you need and the iron each one costs: a bucket for lava and water, shears for leaves, an iron pickaxe for redstone dust |
| lava sources | 4 | lava source blocks to bring: one bucket trip each |
| materials | Nether: quartz in 22 blocks | the stage of the game its materials need: day 1, the Nether (quartz, slime, magma...) or the End |
| chunk columns | 9 | how many 16 x 16 chunk columns it covers |
| storage | 5.4 h (47 slots; 108 poppies/h) | how long its chests and hoppers hold the iron and poppies before they fill |
| hoppers per 1000 iron/h | 9.3 | hoppers for each 1000 iron an hour: each hopper costs the server a little work every tick |
| redstone dust | 789 | the redstone dust its blocks take to craft (a repeater or a comparator 3, an observer 2, a piston 1...): redstone ore needs an iron pickaxe to mine |
Notes from its designer
Carousel: 4 groups of 3 villagers, one per minecart, on 3 concentric loops (inner side 28); the golem's fall through a tripwire releases every cart at once to its next stop; the north stops are the station over the pad. At dusk each cart drops its villager onto its stop's bed and waits there empty; at dawn it picks the villager up from a pocket past the brake.
