- Remove the old sprockets from the undercarriage system. Typically, this involves removing the track chain or loosening it to remove the sprockets. Depending on the model, the sprockets and track chain may be connected in different ways, so take care during this process.
- Cleaning and Inspection
- Before installing the new sprockets, inspect related components, such as the track chain, drive wheels, and other parts. If you find significant wear on these components, it’s best to replace them as well to ensure everything fits properly.
- Clean off any dirt, oil, or debris from the machine to prevent any issues during the installation of the new sprockets.
- Install the New Sprockets
- Position the new sprockets in place and ensure they align correctly with the connecting points. Use hydraulic or other tools to secure the sprockets in place.
- Adjust the tension of the track chain to ensure smooth contact between the chain and sprockets. The chain should not be too tight or too loose.
- Make sure all the bolts and connection points are tightened properly to avoid any issues during operation.
- Test and Check
- After installing the new sprockets, lower the excavator and conduct a brief test run to make sure everything operates smoothly.
- Check for any unusual noises or vibrations, and confirm that the sprockets are installed correctly. If everything seems fine, you can proceed with further testing to ensure the machine runs as expected during regular operations.

After retiring on January 2nd, I decided it was time for a new adventure and purchased a new excavator to replace my Kubota KX161. I chose the Kubota KX080-3, which weighs 18,000 lbs. The machine arrived at the dealer two weeks ago, but they’ve asked me to postpone delivery until the second week of February so they can showcase it at a show.
From a user's perspective, the KX080-3 is a great machine. The cabin is incredibly spacious, offering a lot of comfort. It has two separate hydraulic output circuits, both with proportional flow controls, making operation smooth and efficient. One feature I particularly appreciate is how easy it is to service—thanks to three movable panels on the machine. It also has its own hose and pump system, allowing you to refuel from ground level, which is a fantastic convenience, especially when working in the woods. Additionally, the machine’s key has a built-in security code, making it much harder for someone to steal or use the machine without permission.
Now that I’m retired, I have more time to focus on bigger projects. I’ll take some pictures of the machine once it’s delivered, but as luck would have it, it might snow that day, and the ground could freeze, making things even more interesting.
Thoughts from Others
A few fellow enthusiasts shared their excitement and experiences after learning about my new purchase. Some of them had considered buying a Kubota mini-excavator a couple of years ago but opted to spend their money elsewhere. They were impressed by Kubota's reputation for making durable excavators and expressed interest in getting their own in the future.
Another commenter mentioned their search for a 12,000-lb excavator and wondered if I had any feedback on the KX161, which I had owned before. My KX161 had about 360 hours on it and had been a reliable machine, though a bit small for the projects I had in mind. The main downside was the relatively small cab and the limited hydraulic flow to the auxiliary circuit. Despite this, I would buy another one if I needed a smaller machine. The Kubota machines are known for their reliability, and mine certainly lived up to that reputation.
Upcoming Projects
I have several projects lined up, including building homes for my daughters on their respective six-acre plots. One of the major tasks involves rebuilding a crossway on the back of my property, which requires rerouting a stream and building up flood control banks. Afterward, we’ll begin clearing another 20 acres to plant blueberries.
I’m especially excited about the prospect of using the new excavator for these larger projects. The KX080-3 will make tasks like these much more manageable, especially when it comes to handling rocks, digging, and moving earth.
Some Advice and Tips
When it comes to equipment, a few other forum members weighed in with advice and experiences about using mini-excavators in similar terrains. One mentioned that Goshen, where I live, is known for its abundance of large rocks, and navigating these would be a challenge without the right equipment. That’s why I made sure to order my new excavator with a thumb attachment—a critical tool for picking up rocks, even smaller ones weighing up to 500 lbs.
Others shared stories of using smaller excavators, such as the KX71-3, to move logs or harvest firewood. While I have been using a logging winch for firewood harvesting, I now look forward to using the excavator for these tasks. It’s definitely an upgrade and makes life a lot easier.
On Dealer Support
I also received a lot of positive feedback about dealer support, which is critical when it comes to buying any piece of equipment. One individual recommended the Kubota dealer R&S for their excellent customer service and support, noting that it’s the dealer, rather than the brand itself, that makes a significant difference in the ownership experience.
Final Thoughts
Overall, I am excited about this new chapter and the projects ahead. The KX080-3 will certainly help me tackle the challenges of my land, especially given its extra power and features. From the comments I’ve received, it’s clear that a good machine, backed by solid dealer support, can make a world of difference. I’m looking forward to using it and sharing pictures once it’s officially delivered.
Key Points from the Discussion: - Kubota KX161 Experience: Reliable but small for larger projects, with a need for more hydraulic flow.
- New KX080-3 Features: Spacious cabin, two hydraulic circuits, refuelable from ground level, built-in security code for theft prevention.
- Upcoming Projects: Includes landscaping, building homes, and creating flood control systems on the property.
- The Importance of a Thumb: Critical for rock handling, especially in rocky terrains like Goshen.
- Dealer Support Matters: Solid support from a good dealer, such as Kubota's R&S, makes a huge difference in the long-term experience.

Designed to handle heavy-duty tasks, the root rake attachment helps operators efficiently clear roots, debris, and other materials from the ground, making it a valuable tool for both contractors and DIY enthusiasts working on landscaping or construction projects.
What is a Root Rake?
A root rake is an attachment designed for use with excavators, particularly mini excavators, which are used for clearing vegetation, roots, and other debris from the ground. It features a set of strong, pointed teeth or tines that can penetrate the soil and grab hold of roots, rocks, and other materials. Root rakes are ideal for jobs such as land clearing, stump removal, and general site preparation.
Why Choose a Root Rake for Your Mini Excavator?
- Versatility
Root rakes can be used in a variety of environments, from agricultural and construction sites to residential landscaping. They are especially useful for clearing dense vegetation or untamed ground, making it easier to prepare land for other tasks like grading or construction.
- Efficient Root and Debris Removal
The pointed teeth on the rake allow operators to grab and pull out roots, rocks, and other debris from deep in the soil. This is a highly efficient method compared to traditional hand digging or using other machines. A root rake allows for faster and more thorough clearing of land, saving time and effort.
- Improved Soil Health
By removing roots and debris, a root rake also helps improve soil health. It can aerate the soil and remove stubborn plant material that might otherwise hinder new growth. This can be especially beneficial in preparing land for new planting or landscaping projects.
- Cost-Effective and Time-Saving
Using a root rake attachment is a cost-effective solution for clearing land compared to hiring additional labor or using larger equipment. With a mini excavator and a root rake attachment, operators can accomplish large tasks more quickly and efficiently, reducing the time and cost required for the job.
Choosing the Right Root Rake for Your Mini Excavator
Selecting the right root rake for your mini excavator depends on several factors, including the size of your machine, the type of material you'll be working with, and the scale of your project. Some important considerations include:- Tine Design: Choose a root rake with tines that are durable enough to handle the materials you’ll be clearing. For heavy roots and thick debris, look for a rake with stronger, more robust tines.
- Size and Compatibility: Ensure that the root rake is compatible with your mini excavator’s size and weight. The attachment should not be too heavy for your machine, as this can affect performance and safety.
- Adjustability: Some root rakes come with adjustable arms that can change the width of the rake, allowing for more precise control over the area being cleared. This is a helpful feature for operators who need flexibility when working in confined spaces.
Common Applications of Root Rakes
- Land Clearing
Root rakes are commonly used for clearing overgrown vegetation, such as brush, shrubs, and small trees, from large plots of land. Whether you're clearing land for construction or preparing a site for landscaping, a root rake attachment can help make the job easier.
- Stump Removal
Root rakes can be used to remove smaller stumps, as well as the roots that are left behind. This is especially helpful when preparing the ground for planting new crops or creating a smooth, level surface for construction projects.
- Material Handling
In addition to clearing land, root rakes can be used to handle and move large piles of debris, rocks, and other materials. This makes them useful in various construction and material handling applications, where moving and organizing debris is required.
Conclusion
A root rake attachment is a versatile and valuable tool for any mini excavator owner. Whether you're clearing land, removing debris, or preparing a site for construction, the root rake makes the job faster and more efficient. By selecting the right rake for your machine and application, you can enhance your productivity and tackle tough tasks with ease.
