When using a 2019 John Deere 26G mini excavator, many operators may wonder about the auxiliary hydraulic circuit and how to control it effectively. The ability to control this system can have significant implications for the machine's versatility, especially when using attachments that require hydraulic power. The question of whether there is an on/off valve or switch for the auxiliary hydraulic circuit is crucial for those seeking precise control over hydraulic tools like augers, breakers, or mulchers.
Understanding the Auxiliary Hydraulic Circuit in Mini Excavators
Mini excavators, like the John Deere 26G, are designed for efficiency and versatility in tight workspaces. The auxiliary hydraulic circuit is integral to this versatility, as it allows the operator to run various attachments that require additional hydraulic power beyond the basic functions of the machine’s arm, bucket, and boom.
For example, a hydraulic breaker used for breaking concrete or rock, or a grapple that requires hydraulic flow, would both be powered through the auxiliary circuit. The 26G comes equipped with this capability, offering two auxiliary lines: one for standard flow and one for high-flow applications. This configuration ensures that the operator can adapt to a variety of tasks with ease.
Is There an On/Off Valve for the Auxiliary Hydraulic Circuit?
The answer to whether there is an on/off valve or switch for the auxiliary hydraulic circuit depends on the machine’s configuration and the specific setup of the hydraulic system. On the 2019 John Deere 26G, there isn't a simple on/off switch in the traditional sense, but there are controls that serve a similar function.
The auxiliary hydraulic flow is controlled by the machine’s control panel. This allows the operator to engage or disengage the flow to the auxiliary hydraulics as needed. However, this control is typically not an "on/off" switch but a lever or dial that adjusts the flow rate. This system is designed for flexibility, allowing precise adjustments to match the requirements of different attachments. Additionally, some models may feature an automatic function that engages the hydraulic flow when an attachment is plugged in, which could also resemble an on/off switch in practice.
Technical Details of the Auxiliary System
The auxiliary hydraulic system on the John Deere 26G is designed for ease of use and adaptability. Here are some key features and parameters to consider:
While the auxiliary hydraulic system on the John Deere 26G is generally reliable, operators may encounter a few common issues related to flow control:
The introduction of auxiliary hydraulics to mini excavators revolutionized the versatility of these machines. Before the widespread use of auxiliary systems, mini excavators were limited in the types of attachments they could operate. The hydraulic system allows for the seamless integration of various attachments, turning the mini excavator into a multi-functional powerhouse.
Over the years, manufacturers like John Deere have continually refined their auxiliary hydraulic systems, improving reliability, efficiency, and ease of use. Today, a mini excavator’s hydraulic system is not just a tool for digging; it’s an essential part of many complex operations, from demolition and trenching to landscaping and grading.
Conclusion
The 2019 John Deere 26G mini excavator’s auxiliary hydraulic system is an essential component for operators looking to extend the machine’s capabilities. Although there isn’t a traditional on/off switch, the system offers precise control over hydraulic flow, with both standard and high-flow options available. Regular maintenance, including checking for leaks and ensuring compatibility with attachments, is key to keeping the system running smoothly. With the versatility provided by this auxiliary system, the John Deere 26G continues to be a valuable tool for a wide range of applications in the construction, landscaping, and demolition industries.

Technical Details of the Auxiliary System
The auxiliary hydraulic system on the John Deere 26G is designed for ease of use and adaptability. Here are some key features and parameters to consider:
- Standard Flow Rate: The John Deere 26G provides a standard auxiliary hydraulic flow rate of about 13.2 gpm (gallons per minute), which is sufficient for most attachments.
- High-Flow Option: For more demanding attachments like larger augers or hydraulic mulchers, the high-flow auxiliary circuit offers a flow rate of 19.7 gpm, ensuring powerful performance when required.
- Pressure Settings: The standard system operates at a pressure of 3,000 psi, ensuring that attachments receive sufficient force for various operations. The high-flow option typically operates at 3,000 psi as well, making it suitable for larger, heavier-duty attachments.
- Quick Connect/Disconnect: The auxiliary lines on the 26G are equipped with quick-connect couplers, allowing the operator to easily switch between attachments without the need for additional tools.
While the auxiliary hydraulic system on the John Deere 26G is generally reliable, operators may encounter a few common issues related to flow control:
- Inconsistent Flow: If the flow to an attachment seems inconsistent, the problem might be related to a faulty control valve or a clogged filter. Regular maintenance, including cleaning filters and inspecting hoses for damage, is essential.
- Attachment Compatibility: Some attachments might require specific hydraulic flow settings. If you are using a high-flow attachment with a standard-flow system, the performance could be suboptimal. Always ensure that the flow rate and pressure settings match the attachment’s requirements.
- Leaks: Leaks in the hydraulic system can cause a loss of pressure and inefficient operation. Regularly check the quick-connect couplings and hoses for wear or damage.
