Product Introduction

The KU18 excels as a highly compact yet effective mini excavator, perfectly suited for a variety of light-duty applications. Engineered with a balanced working weight of 1520 kg and powered by a reliable Kubota diesel engine delivering 10.2 kW, it provides consistent, efficient performance. Its 0.04 m³ bucket capacity is designed for precise material handling, while the impressive maximum digging height of 3310 mm ensures excellent reach for tasks in landscaping, utilities, and general site preparation.

Designed for versatility in confined spaces, the KU18 boasts a narrow 1110 mm width and a robust 30% gradeability, allowing it to navigate tight urban job sites, gates, and uneven terrain with ease. With a two-speed travel system reaching up to 3.5 km/h, it moves quickly between tasks. Its substantial digging radius of 3640 mm and maximum digging depth of 2120 mm enhance productivity, while a 2370 mm maximum unloading height supports efficient loading and material placement.

Constructed with operator convenience and long-term reliability in mind, the KU18 features a water-cooled engine for stable operation in varying conditions and a 17-liter fuel tank for extended work cycles. Its 13-liter hydraulic oil capacity supports smooth and responsive system performance. Designed with a clear, user-oriented layout and essential dimensions—including a 3300 mm overall length and 2360 mm height—it provides a practical, dependable solution for daily operations with minimal maintenance requirements.
