This discussion centers on whether a small excavator, such as the John Deere 26G, can be loaded into a 12-foot long by 6-foot wide low-side dump trailer. Users exchanged views about size compatibility, loading techniques, and transport safety considerations.
Main Discussion Points:

• Size Comparison
  The length and width of the 26G excavator generally slightly exceed the internal dimensions of a 12x6 ft trailer. Some users believe directly loading it may be difficult, especially regarding width. Precise measurement of both the machine’s width and the trailer’s interior is essential.
  
• Disassembly and Folding
  Suggestions include partially disassembling or folding the excavator’s boom or arm to reduce dimensions and ease loading. Adjusting the arm and bucket to a transport position can also save space.
  
• Loading Techniques
  Careful use of ramps or loading boards is recommended, ensuring proper angle and stability to prevent the excavator from slipping or tipping. Loading should be performed by experienced operators.
  
• Legal and Safety Considerations
  Transport width limits, height restrictions, and weight regulations must be observed. Properly securing the excavator on the trailer is critical to avoid shifting or loosening during transit.
  
• Trailer Selection
  For frequent transport of the 26G or similar-sized excavators, some users suggest investing in a larger trailer (e.g., 14 ft long or wider low-side dump trailer) to ensure safer and easier transportation.

The Yanmar B32 mini excavator is widely used in landscaping, agriculture, and small-scale construction projects due to its compact size and flexible operation. Users generally express satisfaction with its power and hydraulic system performance. However, maintenance is emphasized, especially regarding hydraulic oil and seal components.
Parts availability is another important consideration before purchase. Having spare parts on hand can help avoid downtime during operations.
For new users, it is recommended to rent the machine first to become familiar with its performance before making a purchase decision. Operators should always pay attention to machine balance to prevent accidents.
Overall, the B32 is considered a cost-effective lightweight excavator suitable for a variety of light-duty applications.

The bucket pins for the Yanmar B50 excavator typically have a diameter of around 35 millimeters. However, the exact length can vary depending on the bucket model and the manufacturing year of the machine.
When replacing bucket pins, it is recommended to first measure the existing pin dimensions precisely to avoid installation issues caused by size mismatches.
To ensure durability and proper fit, it is best to use genuine OEM parts. If opting for generic replacement pins, one must confirm that the specifications match exactly and pay close attention to material quality to maintain operational safety and efficiency.

A user posted on an old forum seeking advice about buying a used Hitachi UH083LC excavator — a model from the late 1980s to early 1990s. Because of its age, he was unsure about maintenance costs, operational performance, and parts availability, so he asked experienced members for their opinions.
1. Main Concerns from the Original Poster

• The machine is inexpensive but has high working hours.
  
• Concerned whether old machines tend to leak oil or have loose structures.
  
• Worried about the difficulty of sourcing spare parts.
  
• Curious about how this model performs compared to other excavators in the same tonnage class.
  

A user on an old forum asked whether Yanmar mini excavators are worth purchasing, especially for farm use, site maintenance, and basic earthwork. He also wanted to know how Yanmar compares with other brands like Kubota, Hitachi, and Komatsu.
1. Advantages of Yanmar Mini Excavators
Several users with Yanmar experience shared highlights:
✅ Reliable Engine Performance
Yanmar is well-known for its diesel engines. Many users find Yanmar mini excavators to have powerful, fuel-efficient, and durable engines.
✅ Good Build Quality and Smooth Operation
Most praise Yanmar’s mature hydraulic system design for smooth, responsive movements and stable operation, making them easy to handle.
✅ Ideal for Small-Scale Site Work
Users generally agree that Yanmar mini excavators have a compact structure, perfectly suited for farms, small homesteads, orchards, and other limited-space operations.
2. Comparison with Other Brands
Some users shared their views comparing Yanmar to Kubota, Hitachi, and Komatsu:

• Compared to Kubota:
  Many feel Yanmar and Kubota are similarly reliable. However, Kubota has a wider dealer and parts network in North America and some regions, while Yanmar’s network is somewhat smaller.
  
• Compared to Hitachi and Komatsu:
  Yanmar tends to be cheaper and simpler for smaller tonnage machines. For larger excavators, Komatsu or Hitachi may offer more options.
  

• Digging ditches, laying pipes, or pond excavation on farms
  
• Site repair and surface leveling
  
• Light grading with dozer blade attachments
  

A user posted on an old forum seeking advice. He plans to buy a mini excavator mainly for digging ditches and site clearing on his own property. Since it’s his first time dealing with such equipment, he’s unsure which brand or size to choose and what details to watch out for. He asked experienced members for help.
1. The User’s Needs
The original poster described:

• Mainly for personal use, occasionally helping neighbors with small jobs.
  
• Wants easy operation and low maintenance.
  
• Has a limited budget and prefers buying secondhand.
  

• Some pointed out that if you only occasionally dig ditches, a tractor with a rear backhoe attachment can suffice. It costs less and is multi-purpose.
  
• However, compared with a genuine mini excavator, a backhoe attachment has much lower efficiency, power, and operational flexibility.
  
• For slightly bigger workloads, most recommend going straight for a proper mini excavator, which is easier to use in the long run.
  

• Most suggest choosing mini excavators around the 3–4 ton class. This weight won’t damage your yard or lawn much, but is much more practical in terms of digging depth and efficiency compared to smaller 1–2 ton models.
  
• Very small machines (around 1 ton) tend to have weak power and slow actions, and can struggle in hard soil or rocky conditions.
  

• The majority recommend mainstream brands like Kubota, Hitachi, and Komatsu because:
  • Reliable quality
    
  • Easier to find parts
    
  • Plenty of repair shops
    
• Users advise avoiding obscure brands or “gray market” imports, which can be difficult to maintain due to scarce spare parts.
  

• Always test the machine yourself: check smooth startup, hydraulic performance (no shaking or leaks), track wear, and swing rotation flexibility.
  
• Inspect hydraulic hoses and cylinders carefully for welding repairs or oil leaks.
  
• Verify the hour meter authenticity, as some machines have tampered low hours.
  
• Reserve budget for maintenance like track replacement and hydraulic pump repairs, which can be costly.
  

• It’s recommended to pick a model with a dozer blade, which helps level the ground and stabilizes the machine on soft terrain.
  
• If you plan to handle logs or rocks, a hydraulic thumb attachment is very helpful for gripping materials.
