Quick Answer
The setting on your spreader depends on several factors, including the type of spreader you have, the product you are applying, and the coverage area. Most spreaders have settings that indicate the application rate in pounds per 1,000 sq ft. Check the product label for the recommended application rate and cross-reference that with your spreader’s settings chart to determine the appropriate setting. Make test passes to dial in the setting before applying product across the entire lawn.
What are the Different Types of Spreaders?
There are a few main types of spreaders:
Handheld Spreaders
Handheld spreaders, also called walk-behind spreaders, are pushed manually. Settings are typically labeled small, medium, and large or have a numerical scale. Handheld spreaders provide good control for small areas.
Push Spreaders
Push spreaders are also walk-behind spreaders but are larger in capacity. The hopper sits on two or four wheels and you push the spreader forwards as you walk. Settings are shown in pounds per 1,000 sq ft. They allow you to cover moderate areas efficiently.
Tow-Behind Spreaders
Tow-behind spreaders attach to the back of an ATV or tractor. They allow you to cover large areas of 1 acre or more. Settings indicate the application rate in pounds per 1,000 sq ft. Tow-behind spreaders provide consistency across large properties.
Broadcast Spreaders
Broadcast spreaders use a rotating disc that scatter products in a wide swath. They provide broad, even coverage and are efficient for covering large areas. Settings are in pounds per 1,000 sq ft. Broadcast spreaders suit both push and tow-behind designs.
Factors That Determine Spreader Settings
The ideal setting depends on several factors:
Product Type
Settings vary greatly depending on if you are spreading granular fertilizer, grass seed, ice melt, or another product. Heavier products require lower settings than lightweight products. Consult the product label for recommended application rates.
Desired Coverage Area
You need to know the square footage of the lawn or property you are treating. This allows you to cross-reference the recommended rate (in lbs per 1,000 sq ft) with your spreader settings chart. Measure your space or look up the square footage for your property.
Spreader Model and Brand
Each spreader model and brand has its own calibration. Settings for one model don’t translate to others. Check the settings chart specific to your spreader make and model. Settings can vary even among different models from the same brand.
Desired Application Rate
The product label gives a recommended application rate, such as 1 lb per 1,000 sq ft. This is the ideal rate for product effectiveness. If you want lighter or heavier coverage, adjust from the recommended rate.
Walking Speed
Your walking pace matters when pushing a spreader. Walking faster requires higher settings to maintain the ideal coverage rate. Stick to a comfortable pace for consistency.
How to Determine the Correct Spreader Setting
Follow these steps to choose the right setting for your spreader:
1. Check the product label
See what application rate is recommended for the product you are using in pounds per 1,000 square feet. This is the starting point for choosing a setting.
2. Find your spreader settings chart
Check the owner’s manual or online listing for a settings chart specific to your spreader make and model. Compare the recommended product rate to the settings chart.
3. Make initial setting adjustments
Choose a setting at or just below the recommended rate on the chart. It’s better to start low and increase as needed. Also account for your walking speed.
4. Perform test passes
Make several passes over a small test strip at your starting setting. Use a collection tray or measure out an area to catch the output.
5. Dial it in
If the output is too low, increase the setting slightly and test again. Decrease if too high. Repeat until dialed in based on the collected output.
6. Apply product
Once the setting is dialed in, walk at a steady, moderate pace as you apply the product over the entire coverage area. Check output occasionally to ensure consistency.
Spreader Settings Chart Examples
Here are two example spreader settings charts for applying 1 lb of nitrogen fertilizer per 1,000 sq ft:
Handheld Spreader Settings
| Spreader Brand | Model | 1 lb/1,000 sq ft Setting |
| Scotts | Deluxe Edgeguard | 4 |
| Earthway | 2600A Plus | 16 |
| Solo | 421 | 4 |
Push Spreader Settings
| Spreader Brand | Model | 1 lb/1,000 sq ft Setting |
| Scotts | Turf Builder Classic Drop | H 1/2 |
| Brinly | P20-500BH | 14 |
| Agri-Fab | 45-0462 | 5 |
These are just examples. Again, check rate recommendations and your specific spreader settings chart. Also perform calibration tests to dial in the optimal setting.
Performing a Calibration Test
A calibration test lets you determine an accurate spreader setting by measuring the output:
Materials Needed:
- Spreader filled with product
- Collection trays
- Scale for weighing output
- Tape measure
Steps:
- Mark a test strip, at least 25 feet long.
- Place trays at intervals within the test strip.
- Make spreader passes back and forth over the test strip at your target setting.
- Weigh the collected product from each tray.
- Compare weights and coverage to rate recommendations.
- Adjust setting and repeat as needed.
This dial-in process helps ensure an accurate application rate. Perform a new test whenever using a different product or spreader.
Key Tips for Spreader Settings
Follow these tips for best results when determining spreader settings:
- Always check product labels for recommended rates.
- Use setting charts specific to your spreader model.
- Make initial settings below recommended rates.
- Perform calibration tests over test strips.
- Walk at a steady, moderate pace.
- Confirm even coverage across lawn areas.
- Re-check settings with each new product.
Taking the time to choose and test the ideal setting results in proper application rates and healthy turf. Check your owner’s manual and product labels, conferred with setting charts, and conduct dial-in testing to determine the optimal spreader setting.
Conclusion
Choosing the right spreader setting requires cross-referencing the product label rate, your spreader settings chart, and performing calibration tests. Start low and increase the setting incrementally after making test passes and collecting output over measured areas. Matching the dialed-in setting to your walking pace allows you to achieve an even, accurate application rate. Always check spreader settings specific to your model and any new products you apply. Proper spreader calibration and setting helps you apply lawn products efficiently and effectively.
