Implement the Switch for Your Harvesting Farm: This step is relatively straightforward. Return to the side of the structure containing the initial stairs and position a solid block atop the gap between the block bearing the Redstone Lamp and the Redstone itself (you might need to initially place a block within the gap and then remove it). Now, facing outward, mount a lever. This lever will serve as the activating switch for the entire machine. Toggle the lever to verify seamless connectivity and piston movement. Refer to the provided image above for enhanced guidance. (minecraft download)
"Lock" the Piston and Position Hoppers: A pivotal step emerges. Now, proceed to position another solid block atop each one that initially encircled the sticky piston. This entails placing a total of three blocks, an effort that poses minimal inconvenience. If any ambiguity persists, consult the first image in this section.
Subsequently, it's time to introduce Hoppers to the assembly. You'll need a total of 6 Hoppers, which you'll situate around the piston, all aimed toward it. To facilitate this placement, create three columns of 2 Hoppers each. Crouch while positioning these Hoppers to ensure seamless layering. If executed correctly, the Hoppers won't repeatedly open their internal inventory. Upon completion, the resultant configuration should mirror the provided image.
Connect the Observers: To operationalize the circuit and enable the machine to fulfill its intended function, you must introduce two Observers oriented toward the initial Redstone Lamp you positioned. These Observers should be placed atop the lamp, facing it directly, as demonstrated in the initial image. This configuration generates a signal vital for the Hoppers' operation. For further guidance, refer to the primary image in this step.
After their placement, you should again place solid blocks. Specifically, situate a block atop the final Observer (a critical placement), and then position two additional blocks on each side. Upon these two columns, distribute Redstone Dust to energize the circuit. For a clearer understanding, consult the subsequent image provided.
Watering the Farm: The utilization of water is essential to maintaining fertile soil for a successful operation. The procedure is elementary. On one side of the line of Redstone blocks you previously positioned—ideally within this space—place two solid blocks. Between these blocks, introduce a ladder, ensuring a gap between the ladder's edge and the adjacent Redstone block. This resultant configuration is showcased in the initial image.
With this setup in place, take a bucket filled with water and pour it into the gap. Consequently, your water reservoir will be prepared, ensuring that the soil remains fertile for cultivation.
Place the soil, Prepare, and Populate the hoppers. Position a plain dirt block atop the piston. Upon placing it, utilize a hoe to till the soil into farmland. Subsequently, introduce Bone Meal into each of the Hoppers you've positioned (you don't need to fill them to capacity). This final element is essential for the optimal operation of the machine, and its function will become evident upon activation.
Initiate Your Farming Machine: Now, acquire either a potato or a carrot. Activate the machine using the switch, observing the motion of the piston and the activation of the Hoppers. With your chosen crop in hand, interact with the moving farmland, automatically accumulating an expanding collection of potatoes or carrots in your inventory. The beauty lies in its versatility; this very machine can be employed with various crops, ensuring a bountiful inventory for your endeavors.
