Hyundai’s Journey into Compact Excavation
Hyundai Heavy Industries, founded in 1972 in South Korea, began as a shipbuilding company but rapidly expanded into construction equipment by the early 1980s. Its Construction Equipment division launched its first excavators in 1988, and by the late 1990s, Hyundai had entered the compact equipment market. The mini excavator segment, particularly models under 6 tons, was developed to meet growing demand for urban and utility excavation tasks. The 35Z-7, a 3.5-ton zero-tail swing model, is part of Hyundai’s 7-series lineup, which was introduced to compete with established brands like Kubota, Takeuchi, and Komatsu.
By 2020, Hyundai had sold over 100,000 compact excavators globally, with strong markets in Southeast Asia, Europe, and North America. The company’s strategy focused on affordability, robust hydraulic systems, and simplified maintenance. Hyundai’s mini excavators are often manufactured in collaboration with Hanix, a Japanese compact equipment specialist, which helped improve reliability and component sourcing.
Understanding the 35Z-7 and Its Class
The Hyundai 35Z-7 is a zero-tail swing mini excavator weighing approximately 3.5 metric tons. This design allows the machine to rotate within its own footprint, making it ideal for confined spaces such as urban construction sites or residential landscaping. Key specifications include:
Price vs Performance Debate
One of the most discussed aspects of Hyundai mini excavators is their pricing. The 35Z-7 is often priced 30–50% lower than premium Japanese or German brands. For example, while a Komatsu PC35MR might retail near $100,000 USD, the Hyundai 35Z-7 could be acquired for around $55,000–$65,000 depending on configuration and dealer incentives.
This price gap raises questions about long-term durability and component quality. While Hyundai machines may not match the precision engineering of Takeuchi or the resale value of Kubota, they offer a compelling value proposition for small contractors and rental fleets. Many operators report that Hyundai’s hydraulic systems and undercarriage components hold up well under typical workloads, though bushings and seals may require earlier replacement than on higher-end machines.
Operator Impressions and Field Experience
Operators who have run both Hyundai and competing brands often note that Hyundai’s cab ergonomics are improving but still lag behind Kubota’s intuitive layout and Takeuchi’s visibility. However, the 35Z-7’s joystick responsiveness and boom stability are praised, especially for grading and trenching tasks.
One contractor in Western Australia demoed the 35Z-7 and found it surprisingly capable, noting that it “felt solid and responsive” even compared to his existing Kubota. He ultimately chose a Takeuchi TB145 due to its higher lift capacity, but acknowledged that the Hyundai would have sufficed for most jobs. This anecdote reflects a common theme: Hyundai minis are often underestimated until tested.
Reliability and Maintenance Considerations
Hyundai’s compact excavators benefit from simplified maintenance access. The engine compartment opens wide, filters are reachable without removing panels, and hydraulic lines are color-coded for easier troubleshooting. However, some users report that electrical connectors and plastic fittings may degrade faster in harsh climates.
Routine maintenance recommendations include:
Comparing Hyundai to Industry Leaders
Let’s break down how Hyundai stacks up against its competitors in the 3–5 ton class:
In 2019, a landscaping firm in Nova Scotia added a Hyundai 55-9A to its fleet. Initially skeptical, the owner chose Hyundai due to budget constraints. After 2,000 hours of operation, including winter snow removal and summer trenching, the machine required only minor repairs—a hydraulic hose and a starter relay. The firm later added a second Hyundai mini, citing “unexpected reliability and low operating costs.”
Final Thoughts and Recommendations
Hyundai mini excavators like the 35Z-7 offer a viable alternative for contractors prioritizing cost-efficiency over brand prestige. While they may not match the refinement of Kubota or Takeuchi, they deliver solid performance for the price. Buyers should:
