Build an Automatic Farm using an Observer in Minecraft

This Minecraft tutorial explains how to use an observer to make an automatic farm.

In Minecraft, you can build a redstone device (using an observer) that automatically harvests your pumpkins as they grow. This farm design works with any plants that grow from a vine such as pumpkins and melons.

Let's explore how to make this automatic farm in Minecraft (watch our video below for detailed instructions on how we built our pumpkin farm).

Required Materials

In Minecraft, these are the materials you can use to build this automatic farm:

2 Hoppers

1 Observer

1 Water Bucket

4 Redstone Dust

9 Stones

1 Iron Hoe

2 Bone Meal

1 Melon Seeds

1 Pumpkin Seeds

1 Piston

Build the Farm

In our automatic farm, we've created a 1 block water source and planted pumpkin seeds on a block of farmland next to the water. We used bone meal to speed up the growth of the pumpkin seeds into a vine. We've left a dirt block for the pumpkin to spawn. We've placed an observer on one side of where the pumpkin will appear and a piston on the other side. The observer and piston are connected by redstone dust.

As the pumpkin plant matures, it will form a pumpkin on the block to the right of the vine.

The observer will detect the pumpkin and send a redstone pulse which will power the piston and break the pumpkin (creating a pumpkin "drop"). The pumpkin drop will either fall in the water or get pushed behind the farm.

We've placed 2 hoppers to store these pumpkin drops. One hopper will catch the pumpkins that fall into the water. The other hopper will catch the pumpkins that are pushed behind the farm by the piston. That's why there are 2 hoppers in this design.

Congratulations, you just learned how to use an observer to make an automatic farm in Minecraft!
