The closing assembly is a critical component of a seeder, responsible for pressing the soil around the seed to create the ideal environment for germination and emergence. However, if the closing assembly is not properly maintained, it can lead to inconsistent seed slot closure, resulting in uneven emergence and ultimately, reduced yields.
In this article, we will discuss the key components of the closing assembly and how to maintain them to ensure consistent seed slot closure and optimal plant growth.
The Closing Wheel Arm
The pivot point of the closing wheel arm is a crucial component to check when inspecting the closing assembly. It is important to look for excessive travel at the back of the arm, as this could indicate that the bushings or pin have excessive wear.
Ideally, there should be no more than half an inch of total travel on the back of the closing wheel arm. If there is more than that, it is time to replace the bushings or pin to prevent further wear and ensure proper functioning of the closing assembly.
The spring in the closing assembly is responsible for providing tension to the closing wheel arm. It is important to check that there is good tension and that the spring is not broken or excessively worn at any point.
If the spring is not functioning properly, it can lead to inconsistent seed slot closure and uneven emergence. Therefore, it is important to inspect and replace the spring as needed.
The Closing Wheel Arm Pin
The closing wheel arm pin is the component that attaches the bolt to the closing wheel arm. There are two inner bushings inside the housing, and the pin rotates within these bushings. However, over time, the pin can wear excessively due to the arm pivoting up and down, as well as covering a lot of acres.
If the pin is excessively worn, it can translate to wear at the back of the arm, leading to inconsistent seed slot closure. It is important to check the pin regularly and replace it as needed to maintain a tight arm and ensure optimal performance of the closing assembly.
