Bobcat 863 High Flow Hydraulic System Overview

[MikePhua]

The Bobcat 863 skid-steer loader, introduced in the mid-1990s, is renowned for its versatility and power. One of its standout features is the high-flow hydraulic system, which significantly enhances its capability to operate demanding attachments. This article delves into the specifications, benefits, and considerations of the 863's high-flow system.
High-Flow Hydraulic Specifications
The high-flow option on the Bobcat 863 provides an auxiliary hydraulic flow of 30.7 gallons per minute (GPM) at a system pressure of 3,000 psi. This configuration delivers approximately 31 hydraulic horsepower, enabling the loader to power a range of high-performance attachments .
Compatible High-Flow Attachments
With the high-flow system, the 863 can efficiently operate various attachments that require substantial hydraulic power:

• Stump Grinders: These attachments benefit from the high-flow system's ability to provide the necessary torque and speed for effective stump removal.
  
• Trenchers: The increased hydraulic flow allows for faster and more efficient trenching, even in challenging soil conditions.
  
• Concrete Planers: High-flow hydraulics enable these attachments to cut through concrete surfaces with ease.
  
• Brush Cutters: The enhanced power facilitates the cutting of dense vegetation and underbrush.
  
• Snow Blowers: High-flow systems improve the performance of snow blowers, allowing for greater snow displacement.
  

Identifying High-Flow Capability
To determine if your Bobcat 863 is equipped with the high-flow option, consider the following:

• Hydraulic Specifications: Check the machine's specifications for the auxiliary hydraulic flow rate. A flow rate of 30.7 GPM indicates the presence of the high-flow system.
  
• Hydraulic Couplers: Inspect the hydraulic couplers for part numbers matching high-flow kits or consult the serial number with Bobcat dealer support .
  
• Operator's Manual: Refer to the operator's manual for detailed information on the hydraulic system and attachment compatibility.
  

Maintenance and Best Practices
To ensure optimal performance of the high-flow hydraulic system:

• Regular Fluid Checks: Periodically inspect the hydraulic fluid for cleanliness and proper levels.
  
• Attachment Compatibility: Always match the attachment's hydraulic requirements with the machine's capabilities to prevent damage.
  
• System Inspections: Regularly check the hydraulic system for leaks or wear, particularly in high-flow components.
  

Conclusion
The high-flow hydraulic system of the Bobcat 863 significantly expands its versatility, allowing operators to tackle a broader range of tasks with specialized attachments. By understanding the system's specifications and adhering to maintenance best practices, users can maximize the performance and longevity of their equipment.
