The Takeuchi TB135, released in the early 2000s, is part of the company’s mini excavator lineup, which includes a range of machines designed for tight workspaces. The TB135 is a short-tail swing model, which means that the rear of the machine doesn't extend beyond the tracks during operation. This feature is particularly useful when working in confined spaces such as urban areas or construction sites with limited space.
Key specifications of the Takeuchi TB135 include:

• Operating Weight: 3,530 kg (7,780 lbs)
  
• Engine Power: 24.7 kW (33.1 hp)
  
• Maximum Digging Depth: 3.85 meters (12.6 feet)
  
• Maximum Reach: 5.8 meters (19 feet)
  
• Hydraulic Flow: 144 L/min (38 GPM)
  
• Bucket Capacity: 0.06-0.2 cubic meters (0.08-0.26 cubic yards)
  
• Dimensions (L x W x H): 5,460 mm x 1,880 mm x 2,520 mm (215 x 74 x 99 inches)
  

With a strong digging capacity and powerful hydraulic system, the TB135 is equipped to handle various tasks such as trenching, lifting, and material handling. It’s ideal for operators looking for a reliable and efficient machine that can fit into small spaces while delivering great power.
Performance and Capabilities
The Takeuchi TB135 is well-regarded for its smooth operation, strong hydraulics, and easy maneuverability. Whether it's working on landscaping jobs, digging trenches, or lifting heavy materials, the TB135 provides consistent power, making it a favorite among operators who require a compact yet powerful machine.
Digging and Excavating Power
The TB135’s hydraulic system offers excellent digging force, especially when used with the right attachments. With a maximum digging depth of 3.85 meters and an impressive digging radius, it is well-suited for digging trenches, preparing foundations, and other tasks that require precise excavation. The mini excavator is also efficient in reaching into tight spots where larger machines would struggle.
Maneuverability
One of the standout features of the TB135 is its compact size. The short-tail swing design allows the machine to work in spaces with limited room, such as near walls, fences, or other obstructions. Despite its compactness, the TB135 offers the strength and versatility typically found in larger machines.
Operator Comfort and Control
Takeuchi designed the TB135 with operator comfort in mind. The machine features a spacious cabin with adjustable controls, clear visibility, and ergonomic seating. This makes it easier for operators to work for extended hours without feeling discomfort. The controls are responsive, and operators can easily adjust the machine's movements to suit various tasks.
Common Issues with the Takeuchi TB135
While the Takeuchi TB135 is generally a reliable machine, like all heavy equipment, it’s not immune to occasional problems. Here are some common issues owners and operators have encountered with this model, along with suggestions for troubleshooting and repair:
1. Hydraulic System Problems
The TB135’s hydraulic system is crucial for its performance, as it powers the boom, arm, and bucket. Hydraulic issues are common in mini excavators, and they can manifest in a variety of ways, such as reduced digging power, slow operation, or total hydraulic failure.
Common symptoms of hydraulic problems:

• Slow or weak boom, arm, or bucket operation
  
• Unresponsive controls
  
• Fluid leakage
  

Troubleshooting steps:

• Check fluid levels: Low hydraulic fluid is often the cause of sluggish performance. Make sure that the fluid is topped up to the recommended level.
  
• Inspect hoses and fittings: Look for cracks, leaks, or loose fittings that could be letting fluid escape.
  
• Test the hydraulic pump: A failing hydraulic pump can cause a loss of pressure, affecting machine operation. If necessary, replace or repair the pump.
  

2. Engine Performance Issues
Engine issues on the TB135, though relatively rare, can cause the machine to run rough or fail to start. Common engine-related issues include clogged fuel filters, air intake problems, or faulty electrical components.
Common symptoms of engine problems:

• Difficulty starting
  
• Engine misfires or runs rough
  
• Loss of power during operation
  

Troubleshooting steps:

• Check the fuel filter: A clogged fuel filter can restrict fuel flow, causing starting problems or engine misfires. Replace the fuel filter if necessary.
  
• Inspect the air filter: A clogged air filter can reduce engine performance. Clean or replace the air filter to ensure optimal airflow.
  
• Check the battery: If the engine fails to start, ensure the battery is fully charged and that the terminals are clean and secure.
  

3. Undercarriage Wear
As with all track machines, the undercarriage of the TB135 is prone to wear and tear, particularly in rough or rocky terrain. Worn-out tracks, sprockets, and rollers can affect the machine’s stability and mobility.
Common symptoms of undercarriage wear:

• Uneven or noisy track movement
  
• Excessive vibration while moving
  
• Tracks jumping off the rollers
  

Troubleshooting steps:

• Inspect the tracks: Check for any visible signs of wear, such as missing or broken track links. Replace worn-out tracks as necessary.
  
• Examine the rollers and sprockets: Worn rollers or sprockets should be replaced promptly to prevent further damage.
  
• Adjust track tension: Tracks that are too loose or too tight can cause problems. Adjust the track tension according to the manufacturer’s specifications.
  

Maintenance Tips for the Takeuchi TB135
Proper maintenance is essential for ensuring the longevity and reliability of your TB135 mini excavator. Regular checks and maintenance routines will help keep the machine running smoothly, reduce the likelihood of breakdowns, and improve overall efficiency.

• Regularly check hydraulic fluid: Ensure that the hydraulic fluid levels are correct and the fluid is clean. Replace the hydraulic fluid and filter according to the manufacturer’s recommended intervals.
  
• Inspect and clean the air filter: A clogged air filter can severely affect engine performance. Clean or replace the air filter every 100-200 operating hours.
  
• Lubricate moving parts: Regularly grease the boom, arm, and bucket joints to prevent excessive wear and keep the machine’s components working smoothly.
  
• Check the undercarriage: Regularly inspect the tracks, rollers, and sprockets for signs of wear. Replace any damaged components and ensure that the tracks are properly tensioned.
