Calibrating Yield Monitor On S680: Easy Step-By-Step Guide

Calibrating a yield monitor on an S680 combine harvester can be a frustrating experience. While some users report no issues with calibration, others have faced erratic behaviour and inconsistent results. The S-series uses a multi-point calibration, which requires multiple calibration loads of typically around 5,000 lbs each, with each load harvested at a different flow rate of grain through the machine. This is in contrast to the single-point calibration used by Deere machines prior to the S-series. The multi-point calibration will not compensate for significant differences in harvested crop moisture, so in crops like corn, which are particularly sensitive to moisture changes, recalibration may be required frequently.

Calibration load size

When calibrating the yield monitor on an S680, the calibration load size is important for accuracy. The load size will depend on the crop being harvested. For example, for wheat yields of around 2t/h, a larger load size may be necessary compared to other crops. It is recommended to use a load size that is representative of the crop being harvested.

When calibrating, it is important to follow the manufacturer's instructions and to perform multiple calibrations at different speeds. This will help the yield monitor build a curve of different yields and speeds, resulting in more accurate data. It is also crucial to ensure that the combine is clean and free of any trash or debris that could affect the calibration process.

In some cases, users have reported issues with yield monitor calibration, even when following the proper procedures. These issues may be related to hardware or software problems, and it is recommended to consult with a dealer or technician for further assistance if calibration issues persist.

Additionally, the moisture content and variety of the crop can impact the accuracy of the yield monitor. For example, in small grains, anytime the moisture or variety changes, recalibration may be necessary. It is also important to note that yield monitors may perform differently in different crops, with some crops, like soybeans, being less accurate than others.

Overall, when calibrating the yield monitor on an S680, it is important to pay attention to the load size, follow proper calibration procedures, and be aware of potential issues that may impact the accuracy of the data.

Calibration load weight

To calibrate the yield monitor on an S680, you will need to perform a calibration load weight test. Here is a step-by-step guide:

Firstly, ensure you are following the official John Deere instructions for calibration. It is important to have a consistent and accurate process. Next, you will need to verify the weights of your loads with certified truck scales. This will ensure that your data is accurate and provide a baseline for calibration.

Now, you can begin the calibration process. Start by performing the mass flow vibration calibration. This will help the machine understand the normal amount of vibration, which can affect the yield readings. Run the combine at full speed with the separator and header engaged.

After this, you can move on to the yield calibration. It is recommended to perform this at different speeds to create a curve of yields and speeds. Calibrate at normal speed, then slow down and repeat the process. This will ensure that your machine is calibrated for a range of conditions.

You will need to calibrate the yield monitor regularly, especially when switching between crops. For example, going from wheat to soybeans and back to wheat can cause the machine to lose accuracy. Calibrate before each new crop and try to stay with that crop setting for consistency.

Finally, keep a record of your calibrations. Use the most recent five calibrations and check the percentage box. Throw out any calibrations that are over 3% or below -3%. This will help you maintain accuracy and identify any issues.

Calibration speed

The calibration speed refers to the frequency at which calibrations are performed. Some users have reported the need to calibrate their yield monitors every hour to maintain accuracy within the same field. This process can be time-consuming and tedious, impacting the efficiency of the harvesting operation.

To optimize calibration speed, it is recommended to perform multi-point calibrations. This involves taking multiple measurements at different speeds and over several days to create a more comprehensive data set for calibration. This approach has shown promising results in improving the accuracy of yield data.

Additionally, it is worth noting that the calibration process can be influenced by various factors, including crop type, moisture levels, and environmental conditions. For instance, yield monitors tend to struggle with small grains, such as wheat, canola, and soybeans, often requiring more frequent calibrations. Changes in moisture content or crop variety within the same field can also impact the calibration, requiring adjustments to the settings.

In conclusion, achieving optimal calibration speed for the S680 yield monitor involves a combination of frequent calibrations, multi-point data sets, and an understanding of the specific crop and environmental factors influencing the accuracy of the yield data.

Calibration frequency

Some users have reported inconsistent yield calibration, requiring recalibration every hour to maintain accuracy for yield maps. This issue seems to affect both new and old machines and persists even after software updates. It is recommended to perform multi-point calibrations and ensure that the most recent calibrations are used, deleting any calibrations with deviations of more than 3%.

In the case of small grains, users have experienced significant challenges with yield monitor accuracy. The S680 yield monitor may struggle with crops like wheat, soybeans, and canola, often requiring frequent recalibration. John Deere has acknowledged these issues, and software updates might be released to address them.

Additionally, the S680 yield monitor's performance can be impacted by factors such as moisture levels, crop variety, and changes in crop type. For instance, switching between wheat and soybeans can cause the monitor to lose calibration. Calibration issues may also arise when harvesting crops with small seeds, such as flax, lentils, or mustard.

It is recommended to pay close attention to the yield monitor's performance and calibrate as needed, especially when encountering the issues mentioned above. While there is no definitive calibration frequency, being proactive and responsive to inconsistencies can help maintain accuracy. John Deere is working on improvements, and retrofitting options like the "Active Yield" feature might be worth considering when they become available for your specific crop types.

Calibration for different crops

Calibration is a critical step in ensuring your yield monitor provides accurate data. Here are some detailed instructions for calibrating your S680 yield monitor for different crops:

Before beginning, familiarise yourself with your yield monitor and its components. Refer to the manufacturer's guidelines, user manuals, on-site support, training sessions, and online resources. Check all cables, connections, and sensors for wear or damage. Ensure that wiring and harness connections are tight.

For multi-crop operations, it is essential to perform separate calibrations for each crop type. The calibration process will vary slightly depending on the crop being harvested. Here are some general steps to follow:

• Consult your manufacturer's guidelines to determine the type of calibration process required (single-point or multi-point). For multi-point calibrations, you will need to harvest multiple loads with different crop flow rates to create a calibration curve.
• Harvest a calibration load for each crop. The weight of these loads will depend on the manufacturer's specifications, but they typically range from 3,000 to 6,000 lbs for multi-point calibrations and can be larger for single-point calibrations.
• Weigh each calibration load using a grain cart or truck scale to obtain an accurate weight.
• Enter these ground truth weights into the yield monitor display.
• Repeat this process for different crop flow rates to ensure accurate yield calculations.
• Pay attention to crop moisture levels. Changes in moisture content can affect the accuracy of your calibration. Recalibrate whenever there is a significant change in moisture levels.
• Regularly inspect and maintain the clean grain elevator chain and sensors. Ensure the sensors are clean and free of debris.
• For optical sensor systems, accurately estimate the grain test weight as it is crucial for generating accurate yield estimates.
• Consult your manufacturer's guidelines for specific instructions and recommendations for calibrating your yield monitor for different crops.

Remember that proper calibration for each crop is essential for accurate yield data, which can then be used for making informed crop management decisions.
