[MikePhua]

The Takeuchi TB135 is a reliable and versatile mini excavator designed to handle a wide range of tasks in tight spaces. Known for its compact design and impressive lifting and digging capabilities, the TB135 is a popular choice for contractors, landscapers, and municipalities. One of the most important decisions when using the TB135 is selecting the appropriate bucket size for various tasks. This article will explore the key considerations for choosing the right bucket size, as well as provide general maintenance tips for keeping the machine in top condition.
Overview of the Takeuchi TB135
Takeuchi, a global leader in the manufacturing of compact construction equipment, introduced the TB135 mini excavator as part of their range of innovative and highly efficient machines. The TB135 features a hydraulic system that ensures smooth and powerful performance, with a compact size that makes it ideal for working in confined spaces. Powered by a 36.5 horsepower engine, the TB135 offers both power and fuel efficiency for smaller jobs like trenching, digging, landscaping, and lifting heavy materials.
A key selling point of the TB135 is its quick-change hydraulic system, which allows operators to easily switch attachments, including various bucket sizes, without losing productivity. The machine's undercarriage design and durable tracks provide stability on uneven terrain, while its spacious and ergonomic cab ensures operator comfort.
Choosing the Right Bucket Size for the TB135
When choosing the appropriate bucket size for the Takeuchi TB135, several factors must be taken into account, such as the type of work, soil conditions, and the machine's lifting capacity. Bucket sizes vary depending on the task, and selecting the wrong size can lead to inefficiency, increased wear on the equipment, or even damage to the machine.
1. Consider the Type of Job
The type of work you plan to do plays a crucial role in determining the appropriate bucket size. For example, if you're digging trenches, a narrow bucket with a smaller width will be more appropriate for precise digging in tight spaces. On the other hand, if you're excavating or lifting loose material like dirt, a larger bucket with a wider opening is more suitable to maximize material handling.

• Trenching: A narrower bucket, typically ranging from 12 to 18 inches, is ideal for trenching applications where accuracy and precision are required.
  
• General Excavation: For general digging or moving larger volumes of material, a medium-sized bucket, around 24 to 36 inches, will provide the balance of power and material handling capability.
  
• Heavy Lifting: If the primary use is lifting or loading heavy materials, a larger bucket of around 40 to 48 inches may be appropriate, provided the weight is within the machine's rated capacity.
  

2. Understand the Machine’s Lifting and Digging Capacity
The Takeuchi TB135 has a digging depth of approximately 9 feet and a maximum digging reach of 14.6 feet. Its lifting capacity is up to 2,600 lbs, which means the bucket size should be selected with these capabilities in mind. Overloading the machine with a larger-than-necessary bucket can strain the engine and hydraulic system, leading to reduced performance or potential damage.

• Small Buckets (12 to 18 inches): Ideal for precise work like trenching, grading, and detailed digging in tight areas. These buckets are lighter and require less hydraulic power, making them easier on the machine.
  
• Medium Buckets (24 to 36 inches): The most common size for general excavation work. They provide an optimal balance between efficiency and the machine’s lifting capacity, allowing for quick work in many construction tasks.
  
• Large Buckets (40 to 48 inches): Suitable for moving larger quantities of material. While they can increase efficiency for certain tasks, they require the machine to handle larger loads, which can strain the hydraulic system and increase fuel consumption.
  

3. Soil Conditions and Material Types
The type of material you are excavating will also influence the bucket size. For instance, digging through loose or sandy soil may allow for the use of a larger bucket since the material is easier to move. Conversely, when working with dense or rocky soils, a smaller bucket is recommended for better control and easier penetration.

• Loose Soil: Larger buckets are better for loose or soft soil, as they can scoop more material in each pass.
  
• Rocky Soil: Smaller, narrower buckets are often more effective for rocky or dense material, as they can penetrate the surface without causing undue strain on the machine.
  
• Mud or Wet Conditions: A larger bucket can be helpful for moving wet soil or mud, as it can scoop larger volumes in fewer passes, saving time.
  

4. Bucket Material and Wear
The material of the bucket itself is also an important consideration. For tougher conditions, buckets made of high-strength steel with wear-resistant coatings or teeth can help extend the life of the bucket and improve digging efficiency. For most tasks, a standard bucket made from quality steel will suffice, but for heavy-duty applications like digging in hard rock or concrete, a heavy-duty bucket with additional reinforcements is recommended.
Maintenance Tips for the Takeuchi TB135
To ensure that your Takeuchi TB135 continues to perform at its best, proper maintenance is essential. Here are some key maintenance tips to extend the machine’s lifespan and improve its efficiency:

1. Check Hydraulic Fluid Regularly: The hydraulic system is one of the most important components of the TB135, and regular fluid checks and changes are necessary to maintain performance. Low hydraulic fluid can lead to sluggish operation and potential damage to the hydraulic pump.
   
2. Inspect the Tracks and Undercarriage: The TB135’s tracks are designed to provide stability, but they require regular inspection for wear and tear. Check for loose or worn-out tracks, and replace them as necessary. Also, inspect the rollers and sprockets for damage.
   
3. Engine Maintenance: Regular oil changes are critical for engine health. The engine oil and filters should be replaced at recommended intervals to prevent unnecessary wear and overheating. Check the air filters regularly, especially in dusty conditions, and replace them if clogged.
   
4. Monitor the Electrical System: Ensure that the battery is fully charged and that all wiring connections are secure. Check the electrical system periodically to avoid starting issues or malfunctions during operation.
   
5. Clean the Machine After Use: Keep the machine clean and free from dirt and debris, especially around the undercarriage and hydraulic lines. This helps prevent overheating and ensures that all components function smoothly.
   
6. Follow Recommended Service Intervals: Always adhere to the service intervals suggested by Takeuchi for the TB135. Regular servicing by a certified technician can help identify and fix potential issues before they lead to costly repairs.
   

Conclusion
The Takeuchi TB135 mini excavator is a powerful and compact machine designed for a wide variety of tasks in construction, landscaping, and municipal projects. Selecting the right bucket size is crucial to ensure efficient operation and to avoid straining the machine's hydraulic and engine systems. By understanding the job requirements, lifting capacity, soil conditions, and material types, you can make an informed decision about which bucket size will provide the best results for your project. Regular maintenance and proper bucket selection will help maximize the productivity and lifespan of the TB135, making it a valuable asset in your equipment fleet.
