[Minecraft] Automatic Wheat Harvesting! How to Build a One-Touch Water Flow Farm.


It’s called the “Water Flow One-Touch Harvest Farm”! It’s a super useful farm where you can harvest crops all at once just by pressing a button.

It’s quite satisfying and convenient to use, so I’m going to explain how to make it in an easy-to-understand way.

By the way, the article title says you can harvest “wheat”, but it’s a device that can be used for almost anything that can be grown in a farm.

*Except for watermelons and pumpkins.

Let me first explain what this device is. This is what it looks like.

It’s quite large.You’ll need a space of about 25 x 15 vertically and horizontally, so be sure to secure a place before you start building the device.

As you can see, it’s a multi-tiered farm, and we’ll be making a three-tiered one this time.

Plant the crops you want to grow in the soil, and when the crops have grown, press the button located next to the device, and…

It’s a farm system where a large amount of water flows down from above, harvesting all the crops at once and automatically collecting them in the chest installed below.

It’s super exhilarating because the harvest is completed in just a few seconds!

We will explain how to create a water flow-style harvesting farm.

Now let’s get into the instructions for building it. We’ll explain it in the following steps:

  • How to make the harvesting section
  • How to make the redstone circuit section
  • How to make the farm section
  • How to create the water flow section.

1. Let’s make the harvesting section.

First, let’s create the mechanism for harvesting crops such as wheat. Start by digging a row of 13 holes in a line.

Expand two of the holes in the center.

Once you have this shape, deepen all the holes you’ve dug so far by one block, making them two blocks deep.

Next, place a chest where you will store the crops you’ve cultivated, such as wheat and potatoes. Put a large chest in the expanded hole.

Then, attach a hopper facing the chest.

Be sure to hold down the shift key when attaching the hopper to the side of the chest. If you don’t, the crops won’t be harvested properly.

Next, place hoppers on either side of the hopper you just placed, all facing in the same direction.

To prevent water from flowing towards the chest, cover the hoppers with glass before flowing water over them. Remember to shift-click while placing the glass blocks.

In addition, place another row of glass on top and let water flow from both ends of the hoppers.

The harvesting section is now complete.

In the image, the back of the chest is forgotten to be dug out, but it is okay to dig one level behind it so that the chest can be opened.

2. Let’s create a redstone circuit.

We will now create a circuit using redstone.

We will create a circuit that allows you to press a button once to start the water flow, and automatically stops it after a few seconds. Redstone circuits can be complex and difficult to understand, so if you’re not familiar with them, just follow the instructions in the images.

First, dig 20 blocks backwards from the water channel side that you created earlier. (only one side)

After digging the trench, you need to lay down the redstone. Place 15 blocks of redstone dust in a row, and then place a redstone repeater at the 16th block to extend the signal. Place four more blocks of redstone dust from the 17th to the 20th block.

The repeater placed on the 16th block does not need to have any delay. It is only placed for the purpose of extending the circuit.

Then, dig 6 blocks parallel to the waterway and lay redstone from there. Place a redstone torch on the top block of the hole.

If possible, go around to the back and make sure the position of the redstone torch is perfectly aligned with the centerline of the device.

Install a button on the block placed on top of the closest redstone to the water canal.

Press the button a few times and check if the redstone torch at the back turns on and off properly. If everything looks good, move on to the next step.

We are in the process of creating the circuit, but let’s also work on the first level of the farm. Place blocks on top of the redstone, covering eight blocks including the one with the button.

Do the same for the other side, too. Then, dig a hole 5 blocks in from the 8th block and pour water into it. Do this from both sides. It should look like this from above.

The part sandwiched between the water and the block in front of it becomes the first level of the farm, so it is okay to till the soil with a hoe at this point.

Let’s return to creating the redstone circuit.

Please dig inward from 3 blocks away from the block placed earlier until just before the column with the opposite block.

I will go back one block, leaving one block space from the front.

Place redstone and repeaters here as shown in the image. Be sure to pay attention to the direction of the repeaters and set the delay to the maximum (right-click 3 times).

Next, continue digging forward and connect the circuit as shown in the image. Again, set the delay of the repeaters to maximum. Finally, make sure to connect the circuit to be just before the previously placed redstone torch.

By doing this, the signal emitted from the button will split into two and the straight signal will give the command to release the water, while the delayed signal from the repeater will give the command to stop the water. This is the mechanism that can be completed with just one touch! Of course, this mechanism can be applied to other devices, so let’s remember it as an example of what can be done. The troublesome redstone circuit is mostly finished here. Let’s move on to making the farm.

3. Let’s start making the farm area.

Moving on to creating the farm. However, we already made the first level of the farm earlier, so we’ll create the second and third levels now. Cover the water and redstone circuit with blocks by stacking soil until just before the redstone torch.

We will cover the water and redstone circuit we placed earlier by stacking soil up to the redstone torch. Be careful not to bury the water or tamper with the redstone repeaters.

Create a wall using blocks for the second level of the farm.This will be for 4 blocks. Do the same on the opposite side with placing blocks.

Next, please dig a hole at this location and pour water in it, just like before.

Cover the water with soil up to the back and create the third level of the farm just like the second level. Place blocks for four spaces,

Add water.

At this point, there should be a gap without a wall of blocks that is three blocks deep, so fill it with blocks and build walls on the sides with blocks as well.

This completes the creation of the farm area. It may have been quite tiring, but all that remains is to create the water flow mechanism! Let’s do our best!

4. Let’s make a device to drain the water.

Let’s make the mechanism to drain water, which is the last step. Please stack the blocks like this on the topmost level that we created earlier. We changed the color for better visibility, but any block is okay.

Additionally, stack blocks in this configuration on top of it:

Please stack blocks in this configuration firmly, as if you don’t, water won’t flow over the entire farm. Please be careful not to make any mistakes!

Next, go around to the back of the mechanism.

Place three blocks on top of the Redstone Torch that is stuck in the ground, and then attach the Redstone Torch to the side of the block like this.

Attach a redstone torch to the top block as well.

Place a dispenser on top of it, and put a water bucket in it.

Finally, once you have finished placing the blocks, tidy up the back with blocks, and it’s complete!

Cover the exposed redstone circuit with blocks, and create a wall-like structure on top to prevent water from flowing back.

Press the button to see if the water flows throughout the field. If it does, then you have passed!

Once you till the soil and plant the crops, it will be a splendid farm.

To prevent crops from flying around when water flows, I stacked glass to make the fence higher. Now, you can harvest without any spills.

My impression after using this device is…

I’ll write a bit about my thoughts after trying to make a water flow harvest field. It’s definitely a convenient and refreshing device, but replanting is tedious! Harvesting is super easy and quick, but planting has to be done manually. Also, when stepping down from the tiers, the soil you’ve tilled gets compacted, so you have to be careful when planting. When I made it in survival mode, I tried making a glass platform in the middle so I could plant from above, but if you fall, the soil gets compacted, and it becomes difficult to plant under the platform.

If you have time, please try making it.
