I’ve been having some issues with thumb interference on my Takeuchi TB180FR excavator. The thumb attachment seems to be interfering with other components during operation, causing operational difficulties. I wanted to share my experience and some potential solutions that I’ve found, in case others are facing the same issue.
Understanding the Issue: Thumb Interference
The problem I’ve been encountering is that the thumb attachment, when operating, interferes with the arm or other parts of the excavator. This interference limits the thumb’s range of motion, making it harder to pick up and handle materials effectively.
The thumb occasionally comes into contact with the arm or the bucket, particularly during certain movements, which reduces the overall efficiency of the machine. This is frustrating because it limits the potential of the machine, especially when working in tight spaces or on delicate tasks.
Initial Solutions Tried
Here’s what I’ve tried so far to resolve the thumb interference issue:

Conclusion
The thumb interference issue on my Takeuchi TB180FR has been a challenge, but with the help of the forum community, I now have several potential solutions to try. Whether it’s a custom thumb design, upgrading to a hydraulic thumb, or rerouting hydraulic lines, I feel optimistic that one of these options will resolve the problem and help me get back to work with improved efficiency.
I’ll keep the forum updated on my progress, and I hope this information helps others who may be facing similar issues with their machines.

Initial Solutions Tried
Here’s what I’ve tried so far to resolve the thumb interference issue:
- Adjusting the Thumb Mounting: I initially tried adjusting the thumb’s mounting points to see if repositioning it could prevent interference. While this helped slightly, it didn’t fully resolve the issue. The thumb still had trouble when reaching certain angles.
- Changing the Thumb Angle: I also experimented with adjusting the angle of the thumb during operation. This helped a little, but the interference was still present, particularly when the bucket was in use.
- Lubricating the Moving Parts: Another suggestion I followed was to ensure that all moving parts were properly lubricated. While lubrication can sometimes reduce friction and improve operation, it didn’t fix the interference problem in this case.
Solutions from the Forum and Community Input
After reaching out to the forum, I received several useful suggestions from the community:
- Custom Thumb Design: A few forum members suggested that I consider a custom thumb design that would have a different mounting configuration or a shorter arm. This would help to avoid the interference between the thumb and the arm/bucket. A shorter or differently angled thumb could be more effective for the tasks I’m performing.
- Using a Hydraulic Thumb: Some users recommended switching to a hydraulic thumb, as it offers more precise control over the thumb's movement. Hydraulic thumbs can be adjusted on the fly, reducing interference and improving overall flexibility in handling materials.
- Relocation of Hydraulic Lines: Another suggestion was to relocate some of the hydraulic lines to create more space between the thumb and other components. By re-routing the hydraulic lines, there may be more room for the thumb to move freely without interfering with the arm or bucket.
- Reprogramming the Thumb: A couple of people mentioned that reprogramming the thumb’s response time or adding a delay might help. Adjusting the speed of the thumb’s movement can prevent it from clashing with the arm or bucket during certain motions.
Next Steps for Resolution
Based on the feedback and my observations, I’m planning to take the following steps:
- Consult with a Fabricator: I will look into having a custom thumb designed that is more compatible with the TB180FR’s arm and bucket, potentially making it shorter or angling it differently to avoid interference.
- Upgrade to a Hydraulic Thumb: I’m considering upgrading to a hydraulic thumb, as this seems like a viable option to improve control and reduce the chance of interference. A hydraulic thumb would allow for more precise adjustments while handling materials.
- Hydraulic Line Rerouting: I’ll also consider rerouting some of the hydraulic lines to make more room for the thumb to operate freely. This may involve some custom work, but it could provide the clearance I need.
