Agri-Fab Spreader Settings Chart (Complete Guide)
Maintaining a healthy and lush lawn requires more than regular watering and mowing. It involves fertilizing your lawn with the right fertilizer and applying it evenly and appropriately.
With the Agri-Fab spreader settings chart, you can get the best results. The Agri-Fab spreader settings chart is important because it provides users with the recommended settings for different materials and spreader models, ensuring even distribution and efficient use of resources.
This is where an Agri-Fab spreader comes in handy. However, you need to understand how to set up your spreader correctly to achieve optimal results.
I’ll explore everything you need about the Agri-Fab spreader settings chart in this article.
What is an Agri-Fab Spreader?

An Agri-Fab spreader is designed to apply fertilizer, seed, and other granular materials to lawns.
These spreaders can be either towed or pushed by hand, and they come with various settings for adjusting the flow rate of the material being spread.
Proper calibration of your Agri-Fab spreader will ensure that you evenly distribute the right material across your lawn.
Why is Calibration Important?
Calibrating your Agri-Fab spreader is crucial because it ensures you apply the correct fertilizer or other material to your lawn.
Applying too little means that your lawn won’t receive the nutrients it needs while applying too much can damage the grass and waste money on unnecessary supplies.
Therefore, calibration helps promote even distribution and efficient use of resources.
How to Calibrate Your Agri-Fab Spreader?
Calibrating your Agri-Fab spreader is easier than you might think. Here are the steps:
- Begin by determining the size of your lawn in square feet. You can do this by multiplying the length of your lawn by its width.
- Next, choose the fertilizer or other material you want to spread.
- The package should have instructions on the recommended application rate, usually in pounds per 1,000 square feet.
- Fill your Agri-Fab spreader with the material you want to spread, and level off the material using a stick or other implement.
- Set your Agri-Fab spreader to its lowest setting and push it across an area of your lawn that you’ve measured to be exactly 1,000 square feet. You can use a walking speed of your choice.
- After spreading the material over 1,000 square feet, weigh the remaining material in your hopper.
- The original and remaining weights differ from the material you used on the 1,000 square feet area.
- Adjust the spreader setting based on the amount of material used during the calibration process.

Agri-Fab Broadcast Spreader Settings For Powdered Fertilizers

Powdered fertilizers are fine and lightweight, requiring a lower spreader setting.
For better results, I recommend using a setting between 2 and 4 for powdered fertilizers, depending on the type of spreader and the size of your lawn.
Using a slow walking speed is best to avoid over-application or uneven distribution.

Agri-Fab Broadcast Spreader Settings For Granular Fertilizers
Granular fertilizers come in different sizes but are generally heavier than powdered fertilizers.
Agri-Fab recommends using a spreader setting between 4 and 9 for granular fertilizers, depending on the granules’ size and the spreader’s type.
A walking speed of 3-4 feet per second is ideal for even distribution.
Agri-Fab Broadcast Spreader Settings For Pelletized Fertilizers

Pelletized fertilizers are denser than granular fertilizers and require a higher spreader setting to ensure even distribution.
I suggest using a setting between 8 and 12 for pelletized fertilizers, depending on the pellets’ size and the spreader type.
Agri-Fab Broadcast Spreader Settings For Organic Fertilizers
Organic fertilizers come in different forms, including powdered, granular, and pelletized. The recommended spreader settings depend on the type and size of the fertilizer particles.
You should consult the manufacturer’s instructions or the Agri-Fab spreader settings chart for guidance on the appropriate settings.
Agri-Fab Broadcast Spreader Settings For Fine Grass Seed
Fine grass seed requires a low spreader setting to avoid over-seeding your lawn.
Using a setting between 2 and 4 for fine grass seed is recommended, depending on the spreader type and the lawn size. It’s best to use a slow walking speed to ensure even distribution.
Agri-Fab Broadcast Spreader Settings For Rough Grass Seed
Rough grass seed is generally larger and requires a higher spreader setting than fine grass seed.
Agri-Fab recommends using a spreader setting between 6 and 10 for rough grass seed, depending on the type of spreader and the size of your lawn.
How Do You Adjust the Agri-Fab Spreader?
Adjusting your Agri-Fab spreader can be easy if you know what to do.
- Determine the material you want to spread per acre or square foot.
- Then, you’ll need to adjust the spreader settings for your desired amount.
- The recommended settings will vary depending on the brand and model of your spreader.
- Finally, ensure you’ve calibrated your spreader before and after making any adjustments, as this can affect its performance significantly.

Frequently Asked Questions (FAQs)
How often should I calibrate my spreader?
I recommend calibrating your spreader at least once a year, but it’s better to do so before the start of every season.
During calibration, you’ll measure the amount of material the spreader discharges over a set distance compared to the recommended settings.
Can I use an Agri-Fab spreader on hilly terrain?
Yes, you can use an Agri-Fab spreader on hilly terrain. However, you should know that the spreader’s distribution rate may vary as the angle of the incline changes.
It’s better to adjust the spreader’s settings to account for the incline to avoid this.
Can I use an Agri-Fab spreader to spread sand?
Yes, you can use an Agri-Fab spreader to spread sand. However, I recommend using a specific type of spreader designed for heavy materials, such as the Agri-Fab 45-0543 or 45-0502 models.
These models have a specially designed feed system optimized for heavy, dense materials like sand.
Conclusion
An Agri-Fab spreader is valuable for maintaining a lawn’s health and appearance. However, achieving optimal results requires proper calibration of your spreader.
Remember to calibrate your spreader regularly, adjust the settings for inclines or heavier materials such as sand, and use smaller or larger models depending on your terrain’s characteristics.
