Get Infinite Spare Parts – No Mods | Rusty's Retirement
When you start a new farm in Rusty's Retirement, you will have a house, a Biofuel Converter, a water well, and a 4×4 crop patch. You will also have 400 Spare Parts and 8 Biofuel. Instead of investing this money directly into crops, I recommend purchasing a Water Bot and a Harvest Bot from the shop. These can be found in the "buildings" tab, which has a small house icon.
They help Rusty harvest crops much faster and free up space for him to build and move crops to the Biofuel Converter. Start by building the Water Bot, then set up the Harvest Bot and fill the field with wheat seeds.
The wheat will grow and be harvested quickly thanks to the bots. With the money, plant two rows of wheat, one row of beets and one row of cabbage.
