J150 Spreader Calibration

Important Note: You will need to perform a Tank Weight Calibration prior to your first Spreader Calibration.

The Spreader Calibration is to ensure accurate material distribution during operation, and is vital when spreading product.

How to perform a Spreader calibration on the EAV J150

Key Steps

Obtain a pair of pliers, as this will help with the removal of the cotter pin for removing the spinner disc.

1. Remove Spinner Disc

Locate the spinner disc underneath the spreader.
Use pliers to remove the locking pin and set it aside.(You will need this when reinstalling the spinner disc)
Spin the bottom locking piece to the left to remove it.
Carefully remove the spinner disc and keep all parts together for reinstalling.

2. Prepare for Calibration

Place a trash can, bucket, or some kind of container underneath the spreader to catch material during calibration.
Lifting the drone over the container (using pallet jacks, tractors, or forklifts) to access the spreader easily is preferred.

3. Access Calibration Settings

Turn on the drone completely.
On the remote controller screen, select 'Auto'.
Select the Settings Icon in the top right corner.
Go to the 'Spreader' settings.
Find the Spreader Calibration section, and on the right select 'Start Calibration.'

4. Perform Minimum Flow Rate Calibration

Create a new template (e.g., 'Test') for calibration.
Use the material of your choice for calibration and load it into the spreader tank.
Set the auger speed to minimum and the time for calibration to 50 seconds. Then select 'Start Calibration'.
Start the calibration and monitor the percentage bar on the screen.
After finishing, it will provide you with the Calibration results, including starting weight, calibration time, remaining weight, and show you how much weight of product was spread, shown as 'Spreader weight.'
After reviewing the results, select 'Next'.

5. Reload Material for Maximum Flow Rate Calibration

After the minimum calibration is complete, reload the material that was just spread into the container back into the spreader tank.

6. Perform Maximum Flow Rate Calibration

Select 'Start Second Calibration' to begin setting up the maximum flow rate.
Set the time for calibration to the lowest setting and the Auger speed material flow rate to 300-450, depending on what product, seed size, and density you are using.
Ensure there is enough product in the tank so that it does not run out of material during this calibration before reaching 100%. If it does run out before calibration is finished, it will be inaccurate, and you should redo the calibration.

7. Finalize Calibration

After calibration, check the remaining material in the tank.
Save the calibration results, which will show the minimum and maximum flow rates.
Adjust ratios if necessary or delete any failed templates.

8. Reinstall the spinner disc

Align the 4 holes on the spinner disc.
Tighten the locking piece back onto the bottom of the disc
Reinsert the cotter pin to keep the disc on securely

Cautionary Notes

Ensure that there is sufficient material in the spreader during both calibrations to avoid incomplete calibration.

Tips for Efficiency

Consider having a second person assist during the calibration process for better efficiency.
Experiment with different densities and seed sizes to find the optimal settings for your specific needs.
