Precision planting is the cornerstone of successful crop production. The John Deere 7200 Planter Rate Chart is your go-to resource for optimizing seeding rates, minimizing waste, and ensuring consistent crop emergence. Whether you’re seeding corn, soybeans, or cotton, understanding how to use the planter’s rate chart correctly can directly impact your yields and bottom line.

(30-Inch Rows)
Crop | Seed Meter | Target Population (Seeds/Acre) | Input Sprocket (Teeth) | Driver/Driven Sprocket | In-Row Spacing (Inches) |
---|---|---|---|---|---|
Corn | Finger Pickup | 28,000 | 48 (Low Range) | 35/24 | 7.5 |
Corn | Finger Pickup | 30,000 | 48 (Low Range) | 29/24 | 7.0 |
Corn | Finger Pickup | 32,000 | 48 (Low Range) | 24/24 | 6.5 |
Corn | Finger Pickup | 34,000 | 18 (High Range) | 35/28 | 6.2 |
Corn | Finger Pickup | 35,600 | 18 (High Range) | 29/28 | 5.9 |
Corn | Finger Pickup | 38,000 | 18 (High Range) | 24/28 | 5.5 |
Soybean | Flat Cell 24 | 140,000 | 48 (Low Range) | 35/24 | 1.5 |
Soybean | Flat Cell 24 | 150,000 | 48 (Low Range) | 29/24 | 1.4 |
Soybean | Flat Cell 24 | 160,000 | 18 (High Range) | 35/28 | 1.3 |
Soybean | Flat Cell 24 | 170,000 | 18 (High Range) | 29/28 | 1.2 |
Notes:
- Input Sprockets: 18-tooth for high-range (higher populations), 48-tooth for low-range (lower populations).
- Driver/Driven Sprockets: Common sizes include 35, 29, 24 (driver) and 24, 25, 26, 27, 28 (driven).
- In-Row Spacing: Calculated as (30 inches × 43,560 sq ft/acre) ÷ population, rounded to one decimal place.
- Field Conditions: For no-till, select a slightly lower population setting to account for reduced wheel slippage (10-15% in tilled soil).

How to Use the John Deere 7200 Rate Chart
To use the rate chart, follow these steps:
- Determine Target Population: Decide the desired seeds per acre based on crop type, soil conditions, and yield goals. For instance, corn at 34,000 seeds per acre, or soybeans at 160,000 seeds per acre.
- Identify Row Spacing: The John Deere 7200 typically operates on 30-inch rows, but confirm your planter’s configuration.
- Select Sprocket Combination: The rate chart lists combinations of input sprockets (e.g., 18 or 48 teeth for high or low range) and driver/driven sprockets on the planter’s transmission shafts. Match the combination to your target population.
- Adjust for Field Conditions: In no-till conditions, wheel slippage is reduced, which may increase seed drop. Adjust to a slightly lower rate (e.g., the next lower sprocket setting) to compensate, as the charts assume about 10-15% slippage in tilled soil.
Common Crop Seeding Rates
Corn Seeding Recommendations
Corn generally performs best at 30,000–34,000 seeds per acre, depending on hybrid and soil moisture.
Soybeans Seeding Settings
For soybeans, you’re looking at 120,000–160,000 seeds per acre, adjusted for row width and soil fertility.
Cotton Planting Details
Cotton requires finer adjustments, typically 35,000–50,000 seeds per acre with tight row spacing.

Factors That Affect Seeding Rates
Ground Speed
Faster speeds increase the chance of skips and doubles. Stick to the recommended 4.5–5.5 mph for accurate drops.
Seed Plate Selection
Each seed size requires a matching plate to ensure proper singulation.
Tire Pressure and Slippage
Inconsistent tire inflation leads to incorrect gear ratio readings. Check tire pressure before each planting session.
Calibrating the John Deere 7200 Planter
Step-by-Step Calibration Guide
- Fill hoppers and mark a 1/100-acre distance (about 174.2 ft for 30” rows).
- Run the planter over the marked strip.
- Count seed drop from each row.
- Adjust gears if output doesn’t match the desired population.
