Doosan has fleshed out the small end of its mini excavator lineup with a trio of new models for the U.S. and Canada. They include the DX35-5, the DX42-5, and the DX50-5. All are Tier 4 emissions standard-compliant.

“Now our customers who need a 3.5-, 4-, or 5-ton (3.2-, 3.6-, or 4.5-metric-ton) mini excavator can purchase, lease, or rent a machine from their local Doosan construction equipment dealer,” says Doosan Infracore North America marketing manager, Aaron Kleingartner.

Standard & Optional Features

Standard equipment on all three of the new mini excavators includes a blade, a suspension seat, and an anti-theft keyless start system. The standard enclosed cab includes heat and air conditioning. Each model can supply 17 to 20 gallons (64 to 76 liters) per minute of auxiliary hydraulic flow for attachments such as augers, breakers, and plate compactors.

Likewise, all three have the option of being equipped with an open canopy and a long arm for greater reach and digging depth. An available angle blade is ideal for backfilling and creating slopes and swales, Doosan says, while an optional quick coupler, bucket, and thumb attachment package adds versatility.

Closeups

The diminutive, 7,909-pound (3,587-kilogram) DX35-5 is the smallest model excavator Doosan currently produces. Its over-the-side digging force benefits from a dual-flange track roller system, which also enhances ride comfort and slewing, the company says.

This 33.5-horsepower (25-kilowatt) diesel mini is only 69 inches (1,752 millimeters) wide which, along with its true zero-swing overhang, recommends it to jobs in close quarters. Its power belies its compact size, however, with 6,968 pounds-force (31 kilonewtons) of bucket breakout force and a maximum digging depth of 10 feet, 3 inches (3.1 meters) with the standard arm.

The DX42-5, meanwhile, is a 9,246-pound (4,194-kilogram) middle child with something to prove. Its 42.7-horsepower (31.8-kilowatt) diesel motor helps it outperform its littermates with a stronger bucket breakout force of 9,183 pounds-force (40.85 kilonewtons). Maximum dig depth with its standard arm is 10 feet, 6 inches (3.2 meters).

The agile DX42-5 is also just as skinny as its 69-inch-wide little brother, so it can squeeze through openings every bit as narrow. Tail swing is a factor, however, with a conventional overhang of 17 inches (432 millimeters) while slewing. In other words, you’ll want to keep the carriage facing straight ahead until there’s more room to rotate.

Finally, the DX50-5 is a bit wider than its smaller siblings at 77.2 inches (1,961 millimeters). That said, its minimal tail swing—a mere 0.6 inches (15 millimeters)—lets it get down to business even in confined spaces.

The DX50-5 has the most power and digging depth of the three units at 49.8 horsepower (37.1 kilowatts) and 11 feet, 7 inches (3.53 meters), respectively. The 10,677-pound (4,843-kilogram) diesel digger also has a breakout force of 8,977 pounds-force (39.93 kilonewtons).

“It’s important to note that these three models will be manufactured in the United States for fast delivery to our U.S. and Canadian dealers and customers,” says Kleingartner.

Bigger Brothers

The three new compact excavators join Doosan’s existing 13,780-pound (6,250-kilogram) DX63-3 and 18,960-pound (8,600-kilogram) DX85R-3 models. They’re slated to hit dealerships in mid-July.
