Automatic Wool Farm — All 16 Colors on DonutSMP
Wool is needed for beds, banners, carpets, and decorative building. An automatic wool farm shears sheep whenever they regrow wool by eating grass — zero maintenance, all 16 colors.
Materials Needed
- • Sheep (16 for all colors, or as many as needed)
- • Dye (16 colors)
- • Grass blocks
- • Observers
- • Dispensers
- • Shears (one per dispenser)
- • Hoppers and chests
- • Redstone dust
- • Building blocks
1. How It Works
When a sheared sheep eats a Grass Block, it regrows wool and the grass turns to Dirt. An Observer detects the Grass → Dirt change, powers a Dispenser with Shears, which shears the sheep instantly. The grass regrows from adjacent grass blocks, and the cycle repeats.
2. Building One Module
1. Place a Grass Block surrounded by walls (1×1 pen) 2. Place a Hopper under the grass block, connected to a Chest 3. Place an Observer facing the Grass Block from the side (detecting block change) 4. Wire the Observer output to a Dispenser facing into the sheep pen from above 5. Put Shears in the Dispenser 6. Place a dyed Sheep on the grass block 7. Ensure at least one adjacent Grass Block is available so the dirt regrows into grass
The sheep eats grass → Observer fires → Dispenser shears sheep → wool drops into Hopper → sheep eats regrown grass → repeat.
3. All 16 Colors
Build 16 modules side by side, one for each dye color: 1. Dye each sheep a different color before placing it 2. Line up all 16 pens with a shared Hopper line feeding into sorted chests 3. Label each chest with signs
This gives you a permanent source of every wool color for any building project.
4. Maintenance
The only consumable is the Shears in the Dispensers — they have 238 uses. Each Shear costs 2 Iron Ingots. With an Iron Golem farm, this is effectively free.
Occasionally check that grass is regrowing properly. If a module stops, the grass might have died — break and replace from an adjacent grass block.
