Understanding the John Deere 8300 Seed Chart
The seed chart for the John Deere 8300 Grain Drill shows recommended seeding rates in pounds per acre (lb/acre) based on crop type. These rates are averages and should always be fine-tuned depending on:
- Seed size and weight
- Desired plant population
- Soil type and moisture
- Local agronomic recommendations
- Row spacing and ground speed

How to Use the Seed Chart Correctly
The seed chart provides a starting point, but actual field performance depends on proper setup and calibration. Follow these steps for the best results:
1. Identify Seed Size
Seed size directly affects how much seed flows through the metering system. Always use cleaned and graded seed for consistency.
2. Set the Correct Seed Cup
The John Deere 8300 typically offers different seed cup openings for small and large seeds. Using the wrong cup can cause over- or under-seeding.
3. Adjust the Drive and Metering System
Use the drill’s sprocket and adjustment levers to match the target seeding rate listed in the chart.
4. Perform a Calibration Test
Before planting:
- Jack up the drive wheel
- Turn it to the recommended number of revolutions
- Collect and weigh seed output
- Adjust settings until the desired rate is achieved
Calibration is especially important for small-seeded crops like canola, alfalfa, and clover.

Factors That Affect Seeding Rates
Even when following the chart precisely, several field variables may require adjustments:
- Soil moisture: Dry conditions may need higher rates
- Planting date: Late planting often requires increased seeding
- Seed germination rate: Lower germination requires higher seeding rates
- Residue levels: Heavy residue may reduce seed-to-soil contact
Always balance seed cost against optimal plant population.
Maintenance Tips for Accurate Seeding
To keep the John Deere 8300 Grain Drill operating accurately:
- Clean seed boxes after each crop change
- Inspect seed cups and flutes for wear
- Lubricate chains and moving parts regularly
- Replace worn sprockets and drive components
- Check tire inflation to maintain the correct ground speed
Consistent maintenance ensures the seed chart remains reliable season after season.
