Auxiliary hydraulics provide extra hydraulic ports and flow to power attachments that require hydraulic power, such as hydraulic hammers, augers, grapples, and trenchers. It allows operators to quickly switch between different attachments without manual connections or modifications.
Understanding Auxiliary Hydraulics in SSL and CTL
Skid Steer Loaders (SSL) and Compact Track Loaders (CTL) have become essential equipment across various industries, including construction and forestry. Renowned manufacturers like Caterpillar, John Deere, Kubota, JCB, and Takeuchi continue to develop more powerful and versatile machines to meet increasing demands.
One of the key reasons behind their popularity is versatility. These machines support a wide range of attachments—buckets, augers, mulchers, breakers, snow plows, and more—allowing operators to perform multiple tasks with a single machine. Thanks to standardized quick-attach systems, users can easily swap attachments across different brands.
Additionally, SSL and CTL machines offer compact size, maneuverability, and lower operating costs, making them ideal for job sites with limited space and a top choice in the rental market.
How Auxiliary Hydraulics Power Your Equipment
Most SSLs and CTLs come equipped with auxiliary hydraulic systems to power attachments quickly and efficiently. There are two primary types of hydraulic configurations:
- Standard Flow (16-26 GPM): Suitable for pallet forks, trenchers, augers, buckets, and hammers.
- High Flow (27-45 GPM): Required for high-power attachments like mulchers, brush cutters, grinders, rock saws, and snow blowers.
⚠️ Important: Before using an attachment, ensure compatibility with your machine’s hydraulic flow rate. Using a high-flow attachment on a low-flow system (or vice versa) can reduce efficiency and potentially damage equipment.
Types of Quick Couplers for SSL & CTL
The most common hydraulic couplings used in SSL and CTL auxiliary hydraulics are:
- Flat Face Quick-Release Couplings (ISO 16028): Commonly found on basic models, these couplers minimize fluid leakage and are easy to clean.
- Cast Iron Hydraulic Blocks with Connect Under Pressure (CUP) Couplings: Designed for heavy-duty applications, these couplers allow easy connection and disconnection even when there is trapped pressure in the hydraulic circuit.
Gute’s Innovative Hydraulic Coupling Solutions
Faster offers a complete range of quick couplings and cast iron blocks designed for construction and forestry applications. One standout feature is their patented decompression system, which automatically relieves trapped pressure, making connection effortless regardless of system conditions.
Additionally, serviceable components such as seals, cartridges, and rear adapters can be quickly replaced to restore full efficiency, further extending the product’s lifespan.
Maintenance Tips for Hydraulic Couplers
To ensure long-lasting performance:
✔️ Clean coupler surfaces before each use to prevent contamination.
✔️ Inspect seals and replace worn components promptly.
✔️ Check for trapped pressure before disconnecting attachments to avoid damage.
