Powerful Performance

The conventional tail swing Doosan® DX42-5K mini excavator is a highly maneuverable machine that lifts heavier and digs deeper. It offers strong bucket breakout force and excellent reach in the 4- to 5-ton size class and can easily navigate even the most congested jobsites.

With a closed center valve, a piston pump, load-sensing hydraulics and cushioned cylinders, the DX42-5K is packed with high-end hydraulic components. Additional features including a dual flange track roller system that improves over-the-side digging and lifting capacity, an integrated lift eye for easier craning and six tie-downs for secure transport make the mini excavator ideal for a wide range of different projects.

Durability and Productivity

Whatever work you’re doing, the DX42-5K mini excavator helps you do more. From digging or dumping soil into trucks to placing hardscape materials, the perfectly sized hydraulic cylinders of Doosan mini excavators turn out best-in-class cycle times.

Your work requires a machine that is as dependable as it is durable. The DX42-5K is built with quality components and updated styling inside and out. Designed with integrated slew brakes, onboard diagnostics, automatic glow plugs and an improved fit and finish on the excavator panels, the DX42-5K allows you to spend less time in the shop and more on the jobsite.

Comfort and Convenience

An expanded cab, more footroom and larger windows make the DX42-5K mini excavator ideal for long days at work. Highly responsive, low-effort joysticks reduce strain. And a strategically placed instrumentation panel with a 5-inch display screen offers key data for improved uptime and productivity. The standard keyless start system also helps reduce unauthorized machine use and theft.


The DX42-5K takes versatility to a new level with a range of enhanced attachments and machine upgrades. Easy-to-reach auxiliary hydraulic couplers on the mini excavator’s arm let you save time and effort connecting hydraulic hoses. An optional clamp diverter valve — also on the excavator arm — allows you to connect another hydraulic attachment without disconnecting hydraulic clamp hoses. Plus, an improved dozer blade with durable design delivers more strength and improved debris shedding.
