What Is a John Deere Seed Plate Chart?
Definition and Purpose
A John Deere seed plate chart is a reference tool that displays the different seed plates compatible with John Deere planters and seeders. It provides information about various seed plates, including their size, compatible seed types, and the number of seeds each plate can dispense per row. The chart helps users determine which seed plate to use for specific crops, seed sizes, and planting conditions, thereby ensuring accurate seed placement and optimal crop emergence.
Why Is It Important?
Choosing the correct seed plate is critical for several reasons:
- Accurate Seed Spacing: Proper seed spacing promotes uniform emergence and optimal plant development.
- Seed Saving: Using the right seed plate minimizes seed wastage and reduces the need for additional seed purchase.
- Efficient Planting: Correct plates ensure consistent seed flow, preventing skips or doubles.
- Crop Yield Optimization: Precise planting directly influences crop yield and quality.
A seed plate chart simplifies the process of selecting the right plate, saving time, reducing errors, and improving overall planting efficiency.

How to Interpret the John Deere Seed Plate Chart
Reading the Chart
A typical John Deere seed plate chart includes the following information:
- Seed Plate Number/Model: The identifier for each specific seed plate.
- Seed Type: The crop or seed species suitable for that plate.
- Seed Size Range: The approximate seed size (diameter or weight) the plate is designed to handle.
- Number of Seeds per Revolution: How many seeds the plate dispenses per turn.
- Seed Spacing: The recommended spacing between seeds.
- Compatibility: The planter models compatible with each plate.
Example of Chart Interpretation
| Seed Plate Number | Seed Type | Seed Size Range | Seeds per Revolution | Compatibility |
|---------------------|------------|-----------------|---------------------|--------------|
| 20C | Corn | 8-10 mm | 200 | John Deere 7000, 7100 |
| 20S | Soybean | 6-8 mm | 250 | John Deere 7000, 7100 |
| 23S | Sunflower | 12-14 mm | 150 | John Deere 7000, 7100 |
This table indicates that Plate 20C is suitable for corn seeds within the specified size, and dispenses approximately 200 seeds per revolution.
