Understanding the Angle Rotary Brush on the Deere 320D: Functionality, Benefits, and Common Issues

[MikePhua]

The John Deere 320D skid-steer loader is a versatile piece of equipment that is often used in construction, landscaping, and various industrial applications. One of the attachments that can be added to the Deere 320D is the angle rotary brush, which is used for sweeping and cleaning surfaces effectively.
This article provides an in-depth look at the angle rotary brush attachment for the Deere 320D, explaining its functionality, benefits, and common issues that users may encounter. Additionally, we will explore how to maintain and troubleshoot the rotary brush to ensure it performs optimally.
What Is an Angle Rotary Brush?
An angle rotary brush, also known as a power broom, is a rotary-powered sweeping attachment commonly used with skid-steer loaders like the John Deere 320D. The attachment consists of a rotating cylindrical brush that can be angled to either side, allowing the operator to clear debris from surfaces such as roads, parking lots, sidewalks, and construction sites.
The brush rotates at high speeds and is designed to move debris, dirt, and other materials off the surface, leaving it clean and clear. The operator can adjust the angle of the brush to direct debris to one side, or they can use the attachment to sweep across a large area in one pass.
Key Features of the Angle Rotary Brush for Deere 320D

1. Rotary Action for Effective Sweeping
   The main feature of the angle rotary brush is its rotary action. The brush consists of bristles mounted on a rotating cylinder, powered by the skid-steer loader’s hydraulic system. This action ensures that debris is efficiently moved across surfaces, even in tough conditions.
   
2. Adjustable Angle
   One of the key advantages of the angle rotary brush is its adjustable angle. This allows the operator to customize the direction of the brush depending on the type of job. Whether it’s sweeping along a curb, clearing large debris piles, or cleaning an open area, the angle adjustment provides flexibility.
   
3. Hydraulic-Powered Drive
   The angle rotary brush uses the skid-steer loader’s hydraulic system to power the brush rotation. This hydraulic system ensures that the brush operates at a consistent speed, which is essential for efficient cleaning. The hydraulic setup also provides enough torque to handle tough sweeping jobs.
   
4. Durable Construction
   Angle rotary brushes are built to withstand the wear and tear of regular use. The brushes are typically made from durable materials, such as steel or high-density polypropylene, which can handle debris without breaking down easily. The brush housing is also designed to endure the harsh conditions often encountered on construction and industrial sites.
   

Benefits of Using the Angle Rotary Brush

1. Improved Efficiency
   The angle rotary brush attachment significantly increases the efficiency of cleaning operations. Instead of manually sweeping debris or using multiple pieces of equipment, the rotary brush allows operators to cover large areas quickly and effectively. The adjustable angle ensures that the brush can be used for various tasks without the need for additional attachments or modifications.
   
2. Time-Saving
   By utilizing the rotary brush, cleaning tasks are completed much faster compared to manual sweeping. This time-saving feature is especially useful for large-scale projects such as road construction, landscaping, and facility maintenance.
   
3. Versatility in Various Environments
   The angle rotary brush is suitable for various environments, from paved surfaces to gravel roads. It is commonly used in construction sites, parking lots, sidewalks, and other outdoor areas that require regular cleaning. The ability to adjust the angle of the brush makes it adaptable to different surfaces and debris types.
   
4. Reduced Labor Costs
   Using an angle rotary brush can reduce the number of workers required for sweeping and cleaning tasks. By allowing a single operator to complete what would normally take several people, businesses can reduce labor costs while improving productivity.
   

Common Issues and Troubleshooting
While the angle rotary brush for the Deere 320D is a durable and reliable attachment, it is not immune to issues. Below are some common problems users may encounter, along with tips for troubleshooting and resolving them:
1. Brush Not Spinning Properly

• Possible Cause: The most common cause of the brush not spinning properly is a hydraulic issue. This could be due to a loss of hydraulic pressure or a blockage in the hydraulic lines.
  
• Solution: Check the hydraulic system for leaks, ensure that the hydraulic lines are clear, and confirm that the pressure is within the correct operating range. If the hydraulic fluid is low, top it up, and check the filters for any clogs.
  

2. Uneven Brush Wear

• Possible Cause: If the brush is not wearing evenly, it could be due to improper angle adjustment or an issue with the brush mounting.
  
• Solution: Regularly inspect the angle of the brush and adjust it as needed to ensure even wear. Additionally, check the mounting of the brush to ensure that it is secure and aligned properly. If the brush is excessively worn, replace it with a new one.
  

3. Brush Jamming or Clogging

• Possible Cause: The brush may become clogged with debris, especially if it is being used to sweep materials like mud or leaves that can collect in the bristles.
  
• Solution: Stop the machine and clear any debris that may be blocking the brush. For tough clogs, use a scraper or wire brush to remove material stuck in the bristles. Regularly cleaning the brush after use will help prevent clogging.
  

4. Inconsistent Performance

• Possible Cause: Inconsistent sweeping performance can be caused by a variety of factors, including worn-out brush bristles, hydraulic issues, or improper attachment installation.
  
• Solution: Inspect the brush for signs of wear and replace the bristles if necessary. Ensure that the attachment is securely mounted to the skid-steer loader and that there are no loose connections. If performance issues persist, check the hydraulic system for proper fluid flow and pressure.
  

Maintenance Tips for Longevity
To ensure that the angle rotary brush operates efficiently over time, regular maintenance is essential. Here are some maintenance tips to keep the attachment in good working condition:

1. Regular Inspections
   Check the brush for wear, tear, or damage after every use. Inspect the hydraulic lines for leaks, and ensure that the mounting bolts are tight.
   
2. Clean the Brush After Use
   After each job, clear the brush of any debris that may have accumulated. This helps prevent clogs and ensures that the bristles last longer.
   
3. Lubricate Moving Parts
   Keep the moving parts of the angle rotary brush well-lubricated. This includes the joints, bearings, and any other parts that experience friction. Proper lubrication reduces wear and extends the life of the attachment.
   
4. Monitor Hydraulic Fluid Levels
   Regularly check the hydraulic fluid levels in the skid-steer loader and ensure that the system is operating at the correct pressure. Low hydraulic fluid can affect the performance of the brush.
   

Conclusion
The angle rotary brush for the John Deere 320D is a highly effective attachment that can significantly enhance the machine’s versatility. Its ability to quickly and efficiently sweep large areas makes it a valuable tool for various industries, from construction to landscaping. By understanding how it works, its benefits, and how to troubleshoot common issues, operators can maximize its performance and extend its service life. Regular maintenance and proper care are key to ensuring that the rotary brush continues to perform at its best.
