I recently acquired a NorTrac Mini Excavator and wanted to share my thoughts and experiences with it. After doing extensive research and considering different models, I decided to go with the NorTrac brand, which seemed to offer good value for money. Here's a summary of my experience so far.
Purchase Decision
I chose the NorTrac Mini Excavator because of its affordable price, strong performance reviews, and versatile capabilities. The model I purchased was specifically designed for both residential and small-scale commercial tasks. The compact size of the machine made it ideal for tight spaces and the type of work I needed to complete.
Initial Impressions
Upon receiving the machine, I noticed that it was well-packaged and the assembly was fairly simple. However, the user manual could have been more detailed, especially for first-time operators. Some of the instructions were a bit vague, but after some trial and error, I was able to get the machine up and running.
Performance and Capabilities
The NorTrac Mini Excavator has impressed me with its performance. Despite being smaller than some other excavators, it offers solid digging power and good lifting capacity. I've primarily used it for trenching, small demolition jobs, and landscaping tasks. The hydraulics work efficiently, and I haven't encountered any significant delays or issues when operating the controls.
The machine's maneuverability in tight spaces is its standout feature. Whether it's working in narrow paths or confined areas, the excavator is agile and can easily navigate around obstacles. It has a smooth operating system, and the controls are responsive, making tasks much easier and faster.
Issues and Maintenance
While the machine has performed well overall, there have been a couple of issues that I encountered after some use:

1. Track Tension: Similar to other mini excavators, I had to adjust the track tension after some usage. If the tracks are too loose or tight, it can lead to operational problems like slipping or jerking during use.
   
2. Hydraulic Leaks: There were some minor hydraulic leaks around the bucket cylinder. This was fixed with some seal replacements, which were fairly inexpensive and easy to do.
   
3. Starting Issues in Cold Weather: The machine can sometimes struggle to start in colder temperatures, especially if it's been sitting idle for a while. I’ve found that using a battery maintainer during the off-season helps alleviate this issue.
   

Recently, I encountered an issue with my NT45 excavator, particularly with the tracks frequently falling off. This problem has been quite frustrating. To help others who may face similar issues, I've compiled my experience and solutions to address this problem.
Problem Description
While using my NT45 excavator, the tracks repeatedly came off, especially when working on more complex terrains. Track detachment not only affects work efficiency but can also cause damage to the equipment, which makes the job very inconvenient. Initially, I thought it was a quality issue with the tracks themselves, but after some inspection, I realized that the problem might be related to track tension adjustment.
Possible Causes

1. Incorrect Track Tension: If the track tension is either too loose or too tight, it can cause the track to fall off. When it's too loose, the track shifts excessively during operation and is more likely to derail. If it's too tight, the friction between the track and the axle increases, which can cause excessive wear on the track and lead to detachment.
   
2. Ground Conditions: Soft or slippery ground, especially muddy sites, can cause the tracks to become unstable and fall off. The weight and load of the excavator also exacerbate this issue.
   
3. Track System Wear: After prolonged use, the rollers and drive wheels in the track system may become worn, preventing the track from maintaining stable tension.
   

1. Check and Adjust Track Tension: Following the machine's manual, I adjusted the track tension to ensure it's neither too loose nor too tight. Regularly checking the tension is necessary to maintain track stability.
   
2. Clean the Tracks and Drive System: I regularly check for debris such as dirt or stones that could block the rollers and drive wheels. If any debris is found, I clean it immediately.
   
3. Replace Worn Parts: I inspected the track rollers, drive wheels, and the track itself for any significant wear. Any damaged parts were replaced promptly. This is an important step in preventing the track from detaching.
   
4. Use Professional Lubricants: I started using appropriate lubricants for the track system, which helps reduce friction and maintain the stability of the track system.
   

Recently, I had the chance to try out my excavator and do some digging. It was a casual session, just to get a feel for the machine and practice a bit. Here’s a summary of my experience, the challenges, and some useful insights for anyone new to excavator operations.
The Setup
I was working with a standard mid-sized excavator, and the goal was to try digging in various conditions and see how the machine performed. I had some basic objectives in mind: get a feel for the controls, test digging in different types of soil, and see how the machine handles different digging angles.
First Impressions
Right off the bat, I could tell that the machine had a lot of power. Even though I was just getting started, it was easy to feel the responsiveness of the hydraulics and the digging capability of the bucket. The excavator felt smooth and easy to control, though it does take some practice to get the movements fluid and precise.
Digging in Different Conditions
I started by working in relatively soft soil, and the excavator had no trouble at all. The bucket dug right in, and I was able to move material quickly. However, things got a bit trickier when I started working with harder ground. I had to adjust my digging technique, applying more pressure and adjusting my digging angle.
One thing I noticed was the importance of the machine’s balance and how it changes depending on the type of material you’re digging through. With softer soil, I didn’t need to adjust much, but with tougher materials, I had to be more mindful of the machine’s stability.
Learning the Controls
For someone who’s not yet fully familiar with excavator controls, there’s a bit of a learning curve. I spent some time getting comfortable with the joysticks for the boom, arm, and bucket. At first, I had a hard time getting the timing right, especially when trying to coordinate multiple functions at once. But after a little practice, I was able to get a better feel for how to move the bucket smoothly and dig efficiently.
Key Takeaways

• Practice Makes Perfect: Excavator operation is all about muscle memory and precision. The more time you spend in the machine, the better you’ll get at making smooth, efficient movements.
  
• Know Your Ground: Different types of soil and material will affect how your machine performs. Make sure you adjust your digging technique based on what you’re dealing with.
  
• Stay Balanced: Always be aware of the machine’s stability, especially when digging in tougher conditions. This will help prevent tipping and maintain safety.

A user recently reached out seeking recommendations for purchasing a cleanup/grading bucket for their 26G excavator equipped with a TAG coupler. The query was directed towards finding a reliable local supplier in the greater Seattle area.
One suggestion was Kitsap Tractor Sales. Although the user had not personally visited the store, they shared that their Yanmar ViO 27-2 came with a sticker from this business on the boom. Kitsap Tractor Sales appears to be a reputable name for purchasing equipment or parts, based on this recommendation.
However, there was some confusion around the term TAG coupler. One user commented that they were unfamiliar with the term. They explained that their Yanmar excavator uses a small hydraulic cylinder between the cross pins, which is controlled from the seat. This setup allows for quick bucket changes in seconds and has been in use since 2004, suggesting a more traditional hydraulic quick coupler system rather than a TAG-style coupler.
For those looking to purchase buckets, the greater Seattle area seems to have reliable suppliers like Kitsap Tractor Sales, but it’s always important to clarify the specific coupler type to ensure compatibility with the equipment.

Old Tao, an experienced excavator operator, entered the excavator industry in 2005. Starting with a Shandong Huaxin agricultural wheeled excavator, he later purchased several machines, including the SANY SY65C and Caterpillar 305CR excavators. In addition to operating the machines, Old Tao also serves as the accountant and secretary for his village. After a busy day, he often shares his experiences and insights on forums with other excavator enthusiasts. Today, we’ll take a closer look at his experience with the SANY SY65C compact excavator.
Purchase Information
Old Tao purchased his SANY SY65C excavator on November 19, 2008, from the Anhui SANY dealer, Hefei Xiangyuan Company. The total price was 370,000 RMB, with a down payment of 109,000 RMB, financed over three years. At the time, he considered several other models, including the Komatsu PC60, Hitachi ZX60, and Kubota KX161, but ultimately chose the SANY SY65C. According to Old Tao, the key reasons for his decision were the excavator's speed, fuel efficiency, and the good reputation of SANY’s Anhui dealership.
Work Conditions
Unlike the Beijing-based users we've previously interviewed, Old Tao primarily works in his hometown area, handling tasks such as rural housing foundation digging, agricultural water conservancy projects, and municipal construction. The work conditions are more rural, with a variety of local construction projects.
Work Efficiency
The SANY SY65C performs excellently in daily tasks, including leveling, trenching, and loading.

The user, Mr. Liang, is from Jixian, Tianjin, and entered the excavator industry in 2002. Initially, he worked with a tractor-converted agricultural excavator. "It broke down frequently, but over time, I became familiar with the machine's workings, which laid the foundation for my future experience in excavator operation and management," says Mr. Liang. Over the years, his family ventured into the excavator rental business, and by 2004, they had purchased multiple units, including one Kubota, one Komatsu, and 17 Case excavators, making them a major user of excavators in the region.
Purchase Experience
In 2004, after earning his first profits from the agricultural excavator, Mr. Liang partnered with relatives to buy a 5-ton foreign brand excavator. However, this machine experienced track issues, and when negotiating with the Beijing dealer, the experience was unsatisfactory. Dissatisfied with the dealer's customer service, Mr. Liang decided to purchase his second excavator from Case, focusing on the CX55B model, which was not yet common in the market. The machine’s imported status, excellent build quality, and the professional service from the Case Beijing dealer convinced him to make the purchase. Mr. Liang emphasizes that besides product quality, the dealer’s customer care and willingness to help customers with flexible policies played a crucial role in his decision.
Working Conditions
Mr. Liang’s excavators don’t typically handle large-scale projects, focusing instead on smaller, scattered jobs in industries like telecommunications, gas, water utilities, and municipal construction. The primary work involves trenching, leveling, and occasional breaking tasks. Since he didn’t purchase the optional breaker pipeline, the machine hasn’t been fitted with a breaker.
Work Efficiency
Mr. Liang is satisfied with the Case CX55B's work efficiency. He attributes this to three key features:

1. Zero Tail Swing
   The Case CX55B's zero-tail-swing feature proved invaluable in tight urban spaces. Many tasks in city areas require maneuverability, and while other machines with rear tails struggle, the CX55B performs well in confined spaces.
   
2. Rubber Tracks
   Mr. Liang chose rubber tracks for this model, which proved beneficial for working in residential areas. Steel tracks can create excessive noise and damage lawns or curbs, but the rubber tracks allow for quieter operations and protect the surfaces in sensitive environments.
   
3. Arm Offset
   The arm offset function of the Case CX55B is especially useful when working along walls, a common task in municipal and telecommunications projects. This feature significantly increased Mr. Liang’s job efficiency and made him more competitive when bidding for projects.
   

1. Air Conditioning Failure
   After approximately 1,000 hours of use, the air conditioning system stopped functioning correctly. The cooling effect was inadequate, which caused significant discomfort during work, especially in the summer. With the windows closed due to the dusty environment, the lack of air conditioning made the work environment unbearable, impacting both work efficiency and operator safety.
   
2. Bucket Issues
   Mr. Liang mentioned that the bucket, initially used without issue, developed cracks after only 200 hours of work. He suspects that the bucket may have been locally manufactured, which led to the premature damage. Eventually, he had to reinforce the bucket himself.
   

Mr. Wang, a user from Henan province who works in construction in Beijing, purchased the Yuchai YC60-8 excavator in 2010. As a regular member of the Yuchai machinery user community in Beijing, Mr. Wang has shared his experience with the machine, focusing on its overall performance, fuel consumption, and issues faced during usage.
Basic Information
The Yuchai YC60-8 is one of the best-selling models from Yuchai Heavy Industry and an upgraded version of the widely-used YC60-7. The machine has received recognition in the industry, having applied for 12 patents and won the "Guangxi Science and Technology Progress Award" and the "Third Prize of the China Machinery Industry Science and Technology Award."
