🌱 Calibration: Finding the Right Seed Drop Rate for Your Cedar Seeder

Calibration is an essential process for farmers using a cedar seeder. It allows you to determine the optimal seed drop rate, ensuring precise and even distribution of seeds for effective planting. In this article, we will explore the different methods of calibrating a cedar seeder and delve into the specifics of calibrating a landscape cedar model GLP 643 for frost seeding. So, let's dig in and discover how to calibrate your cedar seeder accurately!

1. Introduction

Before delving into the calibration process, let's have a brief overview of the importance of calibration and the types of seeds suitable for frost seeding.

2. Calibration: Why is it important?

Calibration plays a pivotal role in ensuring the success of your seeding operation. By calibrating your cedar seeder, you achieve precise seed drop rates, preventing over-seeding or under-seeding. Accurate seed distribution results in optimal plant population, better germination, and ultimately, higher yields. Additionally, calibrated seeders save time, money, and effort by avoiding seed waste.

3. Types of Seeds for Frost Seeding

Frost seeding involves sowing seeds during the late winter or early spring when the ground is still frozen. It is commonly used for pastures and meadows. The most suitable seeds for frost seeding are those that have a minimal risk of displacement due to freezing and thawing cycles. Rye grasses are particularly ideal for frost seeding as they are relatively large and heavy, allowing them to work their way into the soil during these cycles.

4. The Instruction Manual's Specifications

The instruction manuals for cedar seeders often provide limited specifications for different seed types. This lack of detailed instructions can pose a challenge when trying to calibrate the seeder for specific seeds. However, we have alternative methods at hand to help overcome this hurdle.

5. Calibrating the Cedar Using the Seed Box Attachment Method

One of the ways to calibrate a cedar seeder is by using the seed box attachment method. This method involves attaching a seed box or tarp to the bottom of the seeder and driving it a fixed distance in the field. By measuring the weight of the collected seeds, you can calculate the seed drop rate per acre using a specified equation. While this method is effective, it requires additional equipment and may not be suitable under certain weather conditions.

6. Alternative Method: Using the Agitator Shaft

For the landscape cedar model GLP 643, there is an alternative method available. Instead of using the seed box attachment, this method utilizes the agitator shaft to determine the seed drop rate. By turning the agitator shaft a specific number of times, the seed drop can be measured and weighed. This method offers convenience and simplicity, especially when the seed box attachment is unavailable or impractical.

🧪 Step-by-Step Guide: Calibrating the Cedar Using the Agitator Shaft Method

Now let's move on to the step-by-step process of calibrating your cedar seeder using the agitator shaft method. This method allows you to measure the seed drop rate accurately and repeatedly.

Step 1: Prepare the Cedar Seeder

Start by ensuring that the clutch disengagement lever is pulled up, allowing the brushes inside the seeder to turn freely. This prevents the chain from turning when conducting the calibration process. You can also place a tarp or a shower curtain underneath the seeder to collect the dropped seeds for measurement.

Step 2: Determine the Number of Agitator Shaft Revolutions

For the GLP 643 model, the recommended number of agitator shaft revolutions per acre is 1,425. However, for calibration purposes, it is advisable to perform a fraction of this number. Dividing the recommended revolutions by 16 would provide an adequate sample. For example, if you choose to perform an eighth of the recommended revolutions, you would perform around 175 agitator shaft revolutions.

Step 3: Measure and Weigh the Seeds

As you turn the agitator shaft, carefully observe the seed drop and collect the seeds in a cup or container for weighing. Once you have completed the specified number of agitator shaft revolutions, record the weight of the collected seeds.

Step 4: Calculate the Seed Drop Rate

To determine the seed drop rate per acre, multiply the weight of the collected seeds by 16 (the fraction of agitator shaft revolutions) and divide it by the total number of agitator shaft revolutions recommended for an acre. This calculation will give you the seed drop rate in pounds per acre.

▶️ Conclusion

Calibrating your cedar seeder is essential to achieve accurate and consistent seed drop rates, leading to successful seeding operations. Whether you choose the seed box attachment method or the agitator shaft method, following a systematic approach will help you determine the optimal seed drop rate for your specific seeder model and seeding requirements. So, don't overlook calibration! Take the time to calibrate your cedar seeder and ensure productive and efficient planting. Happy farming!
