Why Settings Are Only a Baseline
Each product behaves differently in the spreader, even when using the same settings. Factors that affect distribution include:
- Granule size and weight – Smaller or lighter granules spread less material.
- Spreader condition – Rust, residue, or clogs can alter the flow rate.
- Walking speed – Faster walking decreases material application.
- Weather conditions – Humidity and dampness can reduce flow.
- Overlap technique – Insufficient overlap can cause uneven application.
These differences make calibration essential before each major application.
How to Calibrate the Republic EZ Broadcast Spreader
Follow these calibration steps to find your ideal setting for any product:
- Mark a 10 ft × 10 ft area (100 square feet) on pavement or turf.
- Weigh your product, use 1 pound as your test sample.
- Set the dial to a mid-range number, such as 4.5.
- Walk and spread evenly across the test area.
- Weigh the remaining product to calculate how much was applied.
- Compute your application rate using: Rate (lb/1,000 sq ft)=Test area (sq ft)Weight used×1000
- Adjust the dial, increase for low output or decrease for high output.
- Repeat until accurate, fine-tune until the target rate matches your fertilizer’s label.
- Record the final setting for future use with that specific product.

Best Practices for Spreader Use
- Overlap slightly (20–25%) between passes for consistent coverage.
- Start with a perimeter pass before filling in the center.
- Maintain steady walking pace throughout the application.
- Close gate when stopping or turning to avoid dumping.
- Clean after each use—remove debris and dry thoroughly.
- Lubricate moving parts regularly to ensure smooth operation.
- Store indoors to protect from rust and moisture.
- Recheck calibration every season or after using new products.
Example Calibration Scenario
You’re applying fertilizer that recommends 4 pounds per 1,000 square feet.
- You mark out 100 square feet.
- You weigh out 0.4 pounds of fertilizer.
- Set your dial to 4.5 and spread across the area.
- You only used 0.3 pounds, which is too low.
- Increase dial to 5.0 and repeat.
- This time, you use 0.41 pounds, nearly perfect.
- Record 5.0 as your correct setting for that product.
This ensures accurate and repeatable results every time you fertilize.

Troubleshooting Common Problems
| Problem | Likely Cause | Solution |
|---|---|---|
| Uneven coverage | Inconsistent walking speed | Maintain steady pace |
| Stripes on lawn | Overlap too narrow or uneven | Overlap by 25% each pass |
| Too much material used | Dial set too high | Reduce setting or walk faster |
| Not enough product spread | Dial too low | Increase setting slightly |
| Spreader clogs | Damp fertilizer or residue | Clean hopper and dry thoroughly |
| Rust on metal parts | Poor cleaning/storage | Wash and oil after use |

FAQs
What setting should the broadcast spreader be on?
For most fertilizers, a setting between 4.0 and 5.0 works well on the Republic EZ Broadcast Spreader. However, heavier materials like lime, sand, or ice melt may require higher settings (6–12). Always test on a small area first before treating the entire lawn.
What spreader setting for EZ Seed?
For EZ Seed or similar grass repair mixtures, use a setting between 3.0 and 3.5. These products contain both seed and mulch, so a lower setting helps prevent over-application. If the lawn appears thin after spreading, lightly go over it again using half the amount.
What do the numbers mean on my spreader?
The numbers on your Republic EZ Broadcast Spreader represent the size of the opening in the hopper gate, which controls how much product flows out. A lower number means less material is released (for fine seeds), while a higher number allows more flow (for coarse or heavy materials).
What spreader setting for 13-13-13?
For a 13-13-13 all-purpose fertilizer, a good starting point is 4.5. This setting provides a moderate release rate that suits most lawns. Adjust slightly higher or lower after a small test area to ensure proper coverage without waste.
How to calculate spreader setting?
To find the correct setting:
- Weigh a small amount of product and apply it to a measured test area (e.g., 100 sq ft).
- Measure how much product was used.
- Compare it to the manufacturer’s recommended rate.
- Adjust the dial up or down accordingly until your application matches the target rate.
This method ensures your spreader delivers the right amount of product every time.
Final words
The Republic EZ Broadcast Spreader delivers professional-quality results when properly calibrated and maintained. While most fertilizers and lawn products work well at a dial setting between 4.0 and 5.0, heavier materials like lime or salt may require higher settings.
Always calibrate your spreader to match the product you’re using, walk at a consistent pace, and record your final settings for future reference. With these practices, you’ll ensure even coverage, efficient use of material, and a healthier, more vibrant lawn year-round.
