Takeuchi TL130 Auxiliary Hydraulics Explained

[MikePhua]

TL130 Overview and Hydraulic Context
The Takeuchi TL130 is a compact track loader (CTL) designed for versatility, balancing power, reach, and maneuverability. It weighs about 3,400 kg (≈ 7,500 lbs) and is powered by a 4-cylinder Yanmar engine delivering roughly 49.2 kW at 2,450 rpm, with peak torque around 226–246 Nm.
Auxiliary hydraulics refer here to hydraulic circuits besides drive and lift arms—in TL130, these are used for attachments such as hydraulic breakers, augers, grapples, etc. They require separate flow rate (pump capacity), operating pressure, hoses and couplers, control switches or joysticks, and sometimes optional “high-flow” packages.

Auxiliary Hydraulic Specification on TL130
Main numbers relevant to the TL130’s auxiliary hydraulic system:

• Auxiliary flow rate: 68 liters per minute (≈ 18 gallons per minute).
  
• Operating pressure: about 20.6 MPa (≈ 3,000 psi).
  
• Hydraulic reservoir capacity: 39 liters.
  

The auxiliary hydraulics in the TL130 are “electrohydraulic” with push-button control and a detent option, allowing for proportional flow control.

Terminology Clarification

• Flow rate: the volume of hydraulic fluid the auxiliary pump provides per minute (in this case ~ 68 L/min). Determines how fast an attachment works.
  
• Operating pressure: maximum pressure the auxiliary circuit is designed to handle (≈ 20.6 MPa / ~ 3,000 psi). Exceeding this risk damage.
  
• Electrohydraulic control: using electric switches/buttons to control hydraulic valves, often giving smoother modulation.
  
• Detent: a mechanical or hydraulic “hold” that keeps the flow active without continuously pressing a button. Useful for attachments that need steady flow.
  
• Standard flow vs high-flow: many loaders offer optional high-flow aux hydraulics for more demanding attachments; TL130’s published spec is for standard flow.
  

Practical Performance & Examples
Some working and performance-related examples:

• Attachments like mulchers, stump grinders or trenchers demand higher flow. With ~ 68 L/min flow, the TL130 can power many mid-size attachments, though very large ones may run at reduced performance.
  
• Bucket self-leveling and other loader functions can share hydraulic capacity; auxiliary flow must be sufficient without starving other functions.
  
• Cycle times: Lift arm raise (fully loaded) ≈ 4.2 seconds; lowering (no load) ~ 2.7 seconds; bucket dump time full load ~ 2.7 seconds; curl ~ 2.1 seconds. These are loader-arm cycles—not directly auxiliary use, but indicate hydraulic system responsiveness.
  

Common Issues and Troubleshooting Tips
When auxiliary hydraulics don’t perform as expected, some common causes and checks are:

• Low flow / weak attachment performance: could be due to clogged filters, worn hydraulic pump, or incorrect control valve adjustment.
  
• Pressure drop under load: may indicate leak in hoses or fittings, or internal pump leakage or worn seals.
  
• Heat buildup: running attachments continuously at max flow generates heat; adequate hydraulic oil cooling, fluid type and viscosity matter.
  
• Control issues: if the electrohydraulic switch or button/detent is lagging or sticking, may be electrical or hydraulic valve issues.
  

Suggested Enhancements & Best Practices
To get the best from TL130’s auxiliary hydraulics, consider:

• Use hoses and couplers rated above the machine’s max pressure (≥ 20.6 MPa) to add safety margin.
  
• Keep hydraulic fluid clean and change filters at proper intervals; use recommended fluid viscosity especially in cold or hot climates.
  
• If regularly using heavy or high-flow attachments, verify whether an optional “high-flow” kit exists; even if TL130 does not officially list high-flow option, sometimes aftermarket or dealer options are available.
  
• Warm up the hydraulic system before demanding work; hydraulic fluid viscosity cold is higher, which reduces flow and efficiency.
  

Field Story
A landscaping contractor in the northern U.S. used a TL130 with auxiliary hydraulics to run a mid-size mulching head. In early spring, with cold temperatures, the mulcher spun sluggishly and the flow seemed weak. After checking, they discovered the cooler was partially clogged from winter debris, and fluid was thick (cold). They flushed the cooler, replaced filters, warmed the machine for five minutes before engaging the attachment. Result: flow increased, the mulcher ran closer to expected rpm, and productivity improved ~ 15%.

Conclusion
The TL130’s auxiliary hydraulic system offers solid standard flow (~ 68 L/min) at around 20.6 MPa, which supports a wide variety of attachments. Performance depends heavily on keeping the system clean, maintaining hydraulic components, using appropriate hoses, and matching attachment demand to what the loader can provide. For users needing more power for heavy attachments, verifying whether “high-flow” options exist or selecting lighter attachments may be necessary.
