User Report on Kobelco Excavators: “The Workhorse” – Pros and Cons

[MikePhua]

Kobelco excavators are renowned in the Japanese market for their fuel efficiency, earning them a reputation as the "Earthwork King" and "Shift King" among many users. These excavators have become the preferred choice for numerous construction professionals, especially those concerned with fuel consumption. However, while some enthusiasts view Kobelco machines as almost "legendary," their performance may not meet the high expectations of all users. The actual value of these excavators depends on the specific needs of the operator, and setting realistic expectations is crucial.
Advantages of Kobelco Excavators

1. Fuel Efficiency
   Compared to other brands like Caterpillar and Komatsu, Kobelco excavators stand out for their low fuel consumption. With rising fuel costs, Kobelco’s fuel efficiency becomes even more appreciated. For example, in earthmoving tasks, a 210-liter tank of diesel can last over 15 hours, and the fuel consumption rate on a six-speed setting is around 14-15 liters per hour. The fuel efficiency of Kobelco’s 200 and 210 models is impressive, particularly in smaller machines.
   
2. Speed and Productivity
   When it comes to earthmoving and loading tasks, Kobelco’s speed and fuel efficiency are hard to match. The 200 and 210 models, especially, offer an exceptional level of productivity. These machines provide a noticeable increase in speed and can perform significantly faster than their competitors, maximizing work output and profitability for the operator.
   
3. Reliability and Comfort
   Kobelco machines are known for their durable build. Despite their relatively low engine power, they are well-suited for earthmoving tasks. The operator cabins in Kobelco machines are spacious and comfortable, with ample room for additional personnel, making long hours more manageable. However, the seats tend to be harder, resembling those in older excavator models, which can be uncomfortable for some users.
   

Disadvantages of Kobelco Excavators

1. Delicate Engine Performance
   Kobelco engines are somewhat delicate, meaning they are best suited for earthmoving tasks. The quality of the diesel used is crucial; poor-quality fuel can lead to significant engine wear. If the fuel filter is not regularly replaced with genuine parts, the machine's performance may degrade after about three years, leading to serious problems.
   
2. Complex Electrical System
   One common complaint among users is the complexity of the electrical system. As the machine ages, electrical components tend to malfunction, and repairs can be expensive and time-consuming. This issue is a notable weakness for Kobelco excavators, which is something prospective buyers should consider.
   
3. Lower Resale Value
   While Kobelco machines perform well, their resale value tends to be lower than that of American brands. The steel used in the construction of these machines is thinner compared to some competitors, affecting the machine's overall strength. Consequently, the resale market for Kobelco machines is not as strong, and they may depreciate faster than other brands.
   
4. Frequent Alarm System Alerts
   Kobelco's alarm system is designed to warn users of potential issues before they become serious problems. However, users often find that the alarms can be triggered frequently, sometimes even when there is only a minor issue. While this feature helps prevent major damage, it can be annoying and distracting for operators, especially when the alarms are triggered unnecessarily.
