Doosan Infracore North America is bolstering its mini excavator lineup with the addition of three new models in the 3.5-, 4-, and 5-ton classes: the Doosan DX35-5, DX42-5, and DX50-5.

The new mini excavators will each be available with an enclosed cab, including heat and air conditioning, or an open canopy configuration. Both configurations allow for excellent all-around visibility, especially to the excavator’s attachment.

A standard suspension seat provides comfort for operators, while a strategically positioned deluxe instrument panel provides machine information for operators. A standard keyless start system helps to reduce unauthorized machine use and theft.

Customers can choose between a standard arm or a long-arm option. The long-arm option gives operators more dig depth and reach and reduces the amount of machine repositioning for enhanced productivity. A blade comes standard with all three new models, and an angle blade is available as a factory option. An angle blade makes it easier for mini excavator operators to perform backfill tasks more efficiently, as well as create slopes and swales.

All three new Doosan mini excavators can be equipped with a quick coupler, bucket, and thumb attachment package. Quick couplers allow mini excavator operators to easily change attachments to match the trenching task to the desired bucket width, minimizing over-digging. A thumb is a popular attachment to use with a bucket to effectively grab, lift, and place items, such as debris in site preparation or hardscape materials for a landscaping project.

Operators have access to 17 to 20 gallons per minute of auxiliary hydraulic flow, depending on the model, to provide power to other attachments, such as augers, breakers, and plate compactors.

The DX35-5 is designed with zero tail swing, which makes it an ideal machine for operating on congested jobsites and working next to other objects.

The conventional tail swing, Tier 4-compliant DX42-5 has strong bucket breakout force, dig depth and reach in a highly maneuverable excavator in the 4- to 5-ton class. Its relatively narrow width for a machine in its class provides operators greater ability to navigate through doorways, gates, and other obstacles.

The 4- to 5-ton size class, Tier 4-compliant DX50-5 enables customers to operate in tight spaces. It is a minimal tail swing excavator with less than one inch of tail overhang.
