Choosing Between the KX71 and U35 Compact Excavators: A Comparison

[MikePhua]

When considering the purchase of a compact excavator, two models that often come up for comparison are the KX71 and the U35. Both are popular choices for a variety of construction and landscaping tasks, but they differ in certain key features. Deciding between these two models depends on several factors, including the type of work, the required digging depth, and personal preferences. Below is a comparison of the KX71 and U35 to help you make an informed decision.
Key Differences Between the KX71 and U35

1. Size and Weight
   • The KX71 is slightly more compact than the U35, which makes it better suited for confined spaces or situations where maneuverability is a priority. With its smaller footprint, the KX71 can operate in tighter areas, such as residential yards or small construction sites.
     
   • The U35, being a bit larger, offers a more stable base. This makes it ideal for projects that require heavier lifting or digging in more open spaces. While it’s slightly less maneuverable than the KX71, it compensates with greater capacity and stability.
     
2. Performance and Power
   • Both models are equipped with powerful engines, but the U35 generally has a more powerful engine compared to the KX71, making it better suited for heavy-duty tasks. The additional power can provide faster cycle times and better performance when lifting or digging tougher materials.
     
   • The KX71, while having a slightly smaller engine, is still highly efficient for most tasks, providing a good balance of power and fuel efficiency. If your work involves lighter digging, trenching, or landscaping, the KX71 might be a more cost-effective option.
     
3. Digging Depth and Reach
   • The U35 typically offers a deeper digging depth and longer reach compared to the KX71, which is ideal for digging in deeper or wider trenches. If you need to work on projects like installing utilities or deeper footings, the U35 will give you more flexibility.
     
   • The KX71, while not offering the same reach or depth, is still very effective for most general digging tasks. Its smaller size and more compact design can be advantageous in environments with limited space, where a deeper digging capacity is not a priority.
     
4. Hydraulic Power
   • Both the KX71 and U35 feature advanced hydraulic systems that offer excellent lifting and digging capabilities. However, the U35 tends to have a higher hydraulic flow rate, which translates into more efficient performance when using attachments such as breakers or augers.
     
   • The KX71, with its slightly lower hydraulic output, is still more than capable of handling standard attachments, but may take a bit longer to perform the same tasks as the U35.
     
5. Price and Value
   • The KX71 is generally more affordable than the U35, making it an attractive option for those working with a tighter budget. Its smaller size and lighter weight translate into lower operational costs, including fuel consumption and maintenance.
     
   • The U35, while more expensive, offers a greater return on investment for those requiring more power, capacity, and versatility. If your projects demand a machine with higher lifting capabilities or deeper digging, the additional cost of the U35 may be justified.
     

Considerations for Choosing the Right Model

1. Project Type and Scope
   • If your projects are small to medium-sized and involve landscaping, trenching, or light construction, the KX71 may be the better choice due to its compact design and cost-efficiency.
     
   • For larger projects that require more lifting power, deeper digging, or greater stability, the U35 would be a more suitable option. It can handle a wider range of tasks with greater efficiency, making it a versatile tool for diverse construction needs.
     
2. Space Constraints
   • The KX71 is ideal for work in tight spaces, such as residential yards or small construction areas, where space is limited. Its compact design allows for better maneuverability, making it easier to work in confined environments.
     
   • On the other hand, the U35 requires more space to operate effectively. If you’re working in a more open area or don’t have to worry as much about space restrictions, the U35’s larger size will provide better stability and power.
     
3. Budget
   • Budget is an important consideration when choosing between the KX71 and U35. If you need a more budget-friendly option without sacrificing performance, the KX71 offers great value while being suitable for most common excavation tasks.
     
   • The U35 is a higher investment, but its additional power, capacity, and versatility make it well worth the price for more demanding tasks. If your budget allows and you require more extensive capabilities, the U35 will provide a higher return on investment.
     

Conclusion
Choosing between the KX71 and U35 depends largely on your specific needs, the types of tasks you’ll be performing, and your budget. The KX71 is a compact, cost-effective machine ideal for smaller jobs or spaces, while the U35 offers greater power, stability, and versatility for larger projects. Carefully consider your project scope, space requirements, and budget before making a decision. Both models are reliable and perform well in different situations, so choose the one that best matches your operational needs.
