What size excavator tree stumper?
Selecting the right size excavator tree stumper depends primarily on your excavator's operating weight and the diameter of stumps you need to remove. Generally, for small to medium stumps (up to 600mm diameter), a TN-06 model designed for 7-15 ton excavators is sufficient. For larger stumps (up to 1000mm diameter), you'll need the TN-08 model compatible with 17-23 ton excavators. The jaw opening is a critical factor—the TN-06 offers a 1500mm opening while the TN-08 provides 1700mm. Operating weight must be matched properly to ensure your excavator can safely handle the attachment without compromising stability or hydraulic performance. Professional forestry operations typically require larger models, while contractors handling residential projects can often work effectively with smaller units. Always consider the biggest stump you'll encounter rather than the average size to ensure your equipment can handle your most challenging tasks.
Jaw Opening
The jaw opening of an excavator tree stumper is one of the most critical specifications to consider when selecting the right size for your operations. This measurement determines the maximum diameter of stumps and roots your equipment can effectively grip and remove.
Jaw Opening Measurements
The jaw opening refers to the maximum width between the opened jaws of the tree stumper attachment. For Tiannuo's excavator tree stumpers, the specifications are:
TN-06 Model: 1500mm jaw opening
TN-08 Model: 1700mm jaw opening
This measurement directly correlates with the size of stumps you can efficiently remove. A wider jaw opening allows you to tackle larger diameter stumps without requiring multiple cuts or approaches.
Matching Jaw Opening to Stump Size
When determining the appropriate jaw opening size, consider the typical diameter of stumps in your project area. For residential and light commercial applications where most stumps range from 300mm to 600mm in diameter, the TN-06 model with its 1500mm jaw opening provides ample capacity with some room to spare.
For forestry operations, land clearing projects, or areas with mature trees producing larger stumps (600mm-1000mm), the TN-08 model with its 1700mm opening ensures your equipment can handle even the most substantial obstacles.
Optimizing Operational Efficiency
A properly sized jaw opening not only determines what you can remove but also affects your operational efficiency. An undersized jaw opening may require:
Multiple cuts to process larger stumps
Increased operation time per stump
Additional wear on equipment
Higher fuel consumption
Conversely, selecting a tree stumper with an appropriately sized jaw opening for your typical workload optimizes productivity and reduces operating costs over the equipment's lifespan.
Operating Weight
The operating weight of an excavator tree stumper is a crucial specification that determines compatibility with your excavator and impacts overall performance in the field.
Weight Specifications and Importance
The operating weight refers to how heavy the tree stumper attachment is. This specification is critical because your excavator must be able to safely lift, maneuver, and operate the attachment without strain or instability. Tiannuo offers two primary models with different weight classifications:
TN-06 Model: 10 Ton operating weight
TN-08 Model: 20 Ton operating weight
These weights reflect the robust construction necessary for the demanding task of stump removal, incorporating high-strength steel and durable hydraulic components.
Balancing Weight with Performance
When selecting a tree stumper attachment, there's always a balance to consider between weight and performance. Heavier units typically offer:
Greater durability for handling tough, densely-rooted stumps
Enhanced stability during operation
More powerful cutting and gripping capabilities
Longer service life in demanding conditions
However, a heavier unit requires a sufficiently powerful excavator to operate it effectively. Using an undersized excavator with a heavy tree stumper can lead to decreased hydraulic performance, potential tipping hazards, and premature wear on the excavator's components.
Weight Distribution Considerations
Beyond the total weight, how that weight is distributed affects your excavator's performance. A well-designed excavator tree stumper like those from Tiannuo balances weight distribution to maintain your excavator's stability while operating at different reach distances and angles.
The dual-cylinder design featured in both the TN-06 and TN-08 models helps maintain balanced operation even when tackling off-center stumps or working on uneven terrain. This design consideration is especially important for maintaining safe and efficient operations in challenging environments.
Suitable Excavator
Selecting an excavator tree stumper that properly matches your excavator's specifications is essential for safe operation and optimal performance.
Excavator Size Compatibility
Tiannuo has designed their tree stumpers to work with specific excavator weight ranges:
TN-06 Model: Suitable for 7-15 Ton excavators
TN-08 Model: Suitable for 17-23 Ton excavators
These compatibility ranges ensure that the excavator has sufficient hydraulic power, lift capacity, and stability to operate the tree stumper effectively. Using an attachment that exceeds your excavator's recommended capacity can lead to:
Reduced operational efficiency
Potential safety hazards
Excessive wear on your excavator's components
Void manufacturer warranties
Hydraulic System Requirements
Beyond the weight classification, compatibility also depends on your excavator's hydraulic system. Both TN-06 and TN-08 models utilize a solenoid valve control system that integrates with modern excavator hydraulics.
The hydraulic requirements typically include:
Sufficient hydraulic flow rate (measured in liters per minute)
Appropriate operating pressure (measured in bar or PSI)
Compatible hydraulic connections and control systems
Your excavator's hydraulic capacity must match or exceed the requirements of the tree stumper attachment. Insufficient hydraulic power can result in sluggish operation, overheating of hydraulic fluid, and reduced cutting effectiveness.
Mounting Considerations
The mounting system is another crucial factor in determining excavator compatibility. Most excavator tree stumpers connect to the machine via a quick coupler system, but specifications vary between manufacturers and models.
Tiannuo's design accommodates standard mounting systems found on most major excavator brands, but it's always important to verify compatibility with your specific equipment. Some considerations include:
Quick coupler type and specifications
Pin dimensions and spacing
Hydraulic connection locations and types
Control wiring requirements for solenoid operation
Proper mounting ensures not only functional operation but also that the tree stumper attachment maintains optimal positioning relative to the excavator boom and arm for maximum leverage and efficiency.
FAQ
