The Seed Maker is a piece of Refining Equipment that produces seeds from a harvested crop or one of four foraged items: Wild Horseradish, Spice Berry, Common Mushroom, or Winter Root. It takes 20m to process seeds. 
A Seed Maker can be crafted after reaching Farming Level 9. One Seed Maker is the reward for completing the Dye Bundle on the Bulletin Board. A Seed Maker may occasionally be found in a treasure room in the Skull Cavern.
Seeds per Crop
The Seed Maker can produce 1-3 seeds of the same variety as the input crop (97.51% chance, average of 2 seeds), 1-4 Mixed Seeds (1.99% chance), or 1 packet of Ancient Seeds (0.5% chance).
To avoid buying new seeds, an average of 51% of harvests would need to be sacrificed (= 1 / (0.9751 * 2)) to obtain new seeds for the next growing cycle.
The game creates a pseudo-random number to determine the type and number of seeds produced. Note that Luck does not have any effect:
(# days played) + unique game ID / 2 + (X tileLocation of Seed Maker) + (Y tileLocation of Seed Maker) × 77 + (timeOfDay) 
As a result of the above formula, Seed Maker output is repeatable, and exploitable. By taking note of seed output at specific times and seed maker locations, the player can restart the day, inputting seeds only at locations and times that produce a desired number and type of seeds.
The Seed Maker does not produce seeds from:
- Coffee Bean
- Crystal Fruit
- Fiddlehead Fern
- Fruit Tree Fruit
- Sweet Pea
- Tea Leaves
- Wild Plum
- Any item listed as "Forage" in-game (other than Wild Horseradish, Common Mushroom, and Winter Root)
- 1.3.27: Cactus Fruit (both foraged and farmed) can be placed in the Seed Maker to produce Cactus Seeds.
- 1.4: Can now be stacked in a player's inventory and in chests.
