The New Holland L785 is a robust and reliable skid steer loader, known for its versatility in handling a variety of attachments for different tasks. One of the key features that enhances its functionality is the auxiliary hydraulics system, which allows the loader to operate hydraulic attachments such as grapples, augers, and hydraulic breakers. For a beginner, understanding how auxiliary hydraulics work and how to properly use them is essential for maximizing the machine's potential. This article will provide a detailed guide for newcomers seeking to understand the auxiliary hydraulics system on the New Holland L785.
What are Auxiliary Hydraulics?
Auxiliary hydraulics refer to an additional hydraulic system installed in machinery like skid steers, which powers attachments beyond the main lift and bucket functions. This system operates through a set of hydraulic lines connected to the loader’s hydraulic pump. These lines provide pressurized hydraulic fluid to various attachments, allowing them to perform specific tasks such as digging, lifting, and moving materials with precision.
On the New Holland L785, auxiliary hydraulics are crucial for handling a wide range of attachments, offering more versatility for different job sites and tasks. The system is powered by the same hydraulic pump used by the main loader functions but includes separate controls to manage the flow of hydraulic fluid to the attachments.
Key Components of the Auxiliary Hydraulics System

Key Components of the Auxiliary Hydraulics System
- Hydraulic Pump
The hydraulic pump in the L785 provides the necessary flow and pressure for both the main loader functions and auxiliary attachments. Understanding the pump’s capacity and how it works will help operators know which attachments are compatible and ensure optimal performance.
- Control Valve
The control valve is responsible for directing hydraulic fluid to either the loader’s main lift and bucket cylinders or the auxiliary lines. By switching between these systems, operators can use either the loader functions or the hydraulic attachments.
- Quick-Connect Fittings
Quick-connect fittings allow operators to easily attach and detach hydraulic lines to and from the auxiliary attachments. These fittings are designed to be user-friendly, ensuring quick and secure connections without the need for special tools.
- Hydraulic Lines
The hydraulic lines transport pressurized fluid from the pump to the attachment. They are essential for transferring power to the hydraulic equipment, and ensuring they are in good condition is crucial for smooth operation.
- Auxiliary Hydraulic Controls
The auxiliary hydraulics on the L785 are controlled via a set of buttons or levers inside the operator's cabin. These controls regulate the flow of hydraulic fluid to the attachment, allowing the operator to adjust the speed and force of the attachment's movement.
When using auxiliary hydraulics, the process is straightforward:
- Connecting the Attachment
First, connect the hydraulic lines of the attachment to the quick-connect fittings on the L785. Ensure that the fittings are securely attached to prevent any hydraulic fluid leakage.
- Activating the Auxiliary Hydraulics
Inside the cabin, the operator can switch the hydraulic control valve to direct fluid flow to the auxiliary lines. This action sends pressurized hydraulic fluid to the attachment, powering it for its intended use.
- Adjusting Hydraulic Flow
Depending on the attachment, the flow rate may need to be adjusted to match the requirements of the task. For example, a hydraulic breaker may need higher pressure and flow than a simple auger. Adjust the controls accordingly to ensure the attachment operates efficiently.
- Using the Attachment
Once the auxiliary hydraulics are activated, the operator can begin using the attachment, whether it's lifting, digging, or performing another task. The attachment will be powered by the hydraulic fluid flowing through the lines.
- Disconnecting the Attachment
After completing the task, turn off the auxiliary hydraulics and carefully disconnect the hydraulic lines from the attachment. Always ensure that the attachment is secure before detaching to avoid any safety hazards.
- Weak Hydraulic Pressure or Slow Attachment Response
If the hydraulic attachment is slow to respond or seems underpowered, it could be due to insufficient hydraulic pressure. Check the hydraulic fluid levels to ensure there is enough fluid, and verify that the hydraulic pump is functioning correctly. If the issue persists, check the hydraulic filter for clogs or damage.
- Leaks in the Hydraulic Lines
Hydraulic leaks can reduce the effectiveness of the auxiliary hydraulics and cause fluid loss. Inspect the hydraulic lines and fittings for any visible leaks. If a leak is found, replace the affected line or fitting immediately to prevent further issues.
- Incorrect Flow Rate
Some attachments require specific flow rates to function correctly. If the attachment isn't working as expected, verify that the flow rate matches the attachment’s requirements. Some auxiliary systems have adjustable flow rates that can be fine-tuned to suit the attachment.
- Clogged or Dirty Quick-Connect Fittings
Over time, dirt or debris can accumulate in the quick-connect fittings, preventing a secure connection. Clean the fittings regularly to ensure that they function properly and securely attach the hydraulic lines to the equipment.
- Check Fluid Levels Before Use
Always check the hydraulic fluid levels before operating the auxiliary hydraulics system to ensure that the system is functioning optimally. Low hydraulic fluid levels can cause the system to work inefficiently or lead to damage.
- Wear Proper PPE
When operating heavy machinery with auxiliary hydraulics, ensure that the operator is wearing proper personal protective equipment (PPE) such as gloves and safety glasses to prevent injury.
- Inspect Attachments Regularly
Before using any hydraulic attachment, inspect it for signs of wear, damage, or leaks. Proper maintenance of attachments is essential for safe and efficient operation.
