Compact excavators are one of the most common pieces of equipment on any job site, thanks to their ability to complete a multitude of tasks in tight spaces. Nearly every major equipment OEM offers one, so the choices are seemingly endless.

The following is by no means a comprehensive listing, but instead a roundup of the some of the latest models to hit the market over the past year. Among the machines here, you’ll see a focus on the balance between power and efficiency, as well as ease of operation.

Stay tuned for information on more compact excavator models in the coming weeks...

Hitachi ZX50U-5N - 

The Hitachi ZX50U-5N has a maximum reach of 19 ft 7 in and provides a maximum dig depth of 11 ft 7 in.

Hitachi Construction Machinery Americas Inc. (HCMA) introduced a slew of new excavators last spring, its first product intro since ending its decades-long joint venture with John Deere.

With its reduced tail-swing design, independent swing boom and 360-degree rotation, the 10,560-lb ZX50U-5N is designed for working in congested areas. 

The ZX50U-5N has a maximum reach of 19 ft 7 in and provides a maximum dig depth of 11 ft 7 in. A backfill blade allows the excavator to fill or grade while an optional all-hydraulic blade angles 25 degrees left or right, for improved efficiency in grading and backfilling.

A standard quick-coupler-equipped, boom-mounted auxiliary line simplifies attachment hookup on the ZX50U-5N. An auxiliary function lever (AFL) is available with an analog switch, trigger switch and horn for running attachments such as a breaker or an attachment with swing.

The ZX50U-5N allows the engine speed to be matched to the job with power/economy work modes, a feature usually only available on larger excavator models. The power mode provides higher engine speeds for most general digging work, while the economy mode reduces engine speed for lighter digging jobs. This results in lower noise and decreased fuel consumption.

The excavator also uses the Hitachi Triple H (HHH) hydraulic system, which enables combined operations by adjusting the optimal flow rate for all actuators. This gives the operator the freedom to provide simultaneous control inputs with no impact on machine performance.

A Tier 4 Final compliant, direct-injected Yanmar engine produces 36.3 net horsepower, providing a high torque level for more pull-through power, according to Hitachi.

The rubber tracks on the ZX50U-5N feature a unique steel core that resists cracking. Large-diameter drive sprockets and track idlers further increase undercarriage durability.

Doosan -7 Series - 

Doosan’s new -7 Series mini excavators are now available through dealers in the U.S. and Canada.

Doosan Infracore North America teased its all-new line of next-generation minis with the 5-ton DX50Z-7 on display at World of Concrete last January. The current

Integrated into the excavator design, additional counterweight enhances sructural durability while enabling offset digging without the need to reposition the machine

launch includes four new models, with more mini excavators to be announced in the coming months.

Designed and manufactured by Doosan, these new models are equipped with Doosan engines and diagnostics. The first four excavator models include the zero tail swing DX27Z-7, DX35Z-7 and DX50Z-7, as well as the reduced tail swing DX55R-7.

Customers can get more productivity from the -7 Series mini excavators, thanks to an increase in counterweight, according to Doosan. Integrated into the excavator design, the additional counterweight enhances the excavator’s structural durability while enabling offset digging without the need to reposition the machine.

Lift-over-side capacity is also enhanced because of the machines’ integrated counterweight design.

A long arm design is available as an option for select new models. The longer arm provides operators with greater reach, dump height and dig depth, and operators don’t need to reposition the machine as often, which improves productivity.

Adding a new size class to the North American lineup, the 24.7-hp, 6,171-lb DX27Z-7 includes features brand new to line, including a rearview camera that allows operators to navigate a full 360 degrees on job sites. Other features include a 3-foot 7-inch standard-thumb-ready arm and an 11.8-inch rubber track undercarriage.

Bobcat’s Platimum, limited edition E35 -

Bobcat is offering a special “Platinum Package” for select machines, including the platinum edition of the E35 33-hp compact excavator.

Features of the E35’s platinum package include a rearview camera installed, LED lights kit, five-year subscription for Bobcat Machine IQ telematics and more

The limited-time offering is available at select Bobcat dealerships and is meant to extend beyond the offerings of the machines’ deluxe and premier packages for added performance and comfort.

Features of the E35’s platinum package include a rearview camera installed, LED lights kit, five-year subscription for Bobcat Machine IQ telematics, an engine block heater, auto HVAC cab, 7-inch touch display screen, Bluetooth radio, a heated high-back suspension seat, motion alarm, long arm, angle blade, clamp diverter valve, and hydraulic X-Change.

It also includes Bobcat MaxControl which allows operators to control the machine with an iPhone app. 

Earlier this year, Bobcat introduced two electric compact excavators, the E32e and E10e, to its stable of compact battery-powered alternatives, as well as three new compact excavators to its R2 Series. 

Takeuchi TB 335R -

Takeuchi has added the new generation TB335R minimal tail swing compact excavator to its TB300 Series.

The TB335R has an operating weight of 8,290 lbs, a maximum bucket breakout force of 6,090 lbs and a maximum arm digging force of 4,630 lbs

The excavator is powered by an EU Stage V/EPA Tier 4 emission-compliant engine delivering 24.4 hp and a maximum torque of 70.6 ft-lbs.

There are two two working modes – Standard and ECO – allowing operators to match the mode to the task at hand, choosing fuel savings or more power as desired.

The TB335R features a fully redesigned interior with one-touch controls, jog dial, high-definition color monitor, and high-back suspension seat with fore/aft/tilt and multiple height adjustments. Low-effort hydraulic pilot controls serve as an extension of the operator, delivering precise control and minimizing fatigue. 

This last spring, Takeuchi unveiled its TB2150R, a 15-ton excavator with a fixed boom arrangement and reduced tailswing design.

Yanmar upgraded VIO17-1E AND VIO25-6B - 

Yanmar has been upgrading its line of mini excavators, and now brings two more models up to speed. The ViO17-1E and ViO25-6B have been redesigned for improved operator comfort, convenience and ease of use, as well increased efficiency, the company said.

The ViO17-1E offers a 4,023-lb operating weight and 14.5-hp engine while the ViO25-6B features a 5,908-lb operating weight and 20.4-hp engine. Both models

The updated ViO17-1E and ViO25-6B have been upgraded to a four-point tie system for easier loading and unloading as well as reliable stability during transport

feature a light footprint for minimized damage to soft, delicate surfaces in landscaping, residential and sculpting applications. Despite their small size, the models feature dig depths of 7 feet, 7 inches for the ViO17-1E and 10 feet for the ViO25-6B.

Powered by Yanmar’s well-known diesel engine, the ViO17-1E and ViO25-6B are built with true zero tail swing technology to help protect both the structure the machine is working next to and the machine itself in tight spaces.

The ViO17-1E has retractable undercarriage that allows operators to hydraulically extend and retract the track width, making it even easier for the machine to access narrow job sites.

With the redesign, Yanmar focuses on efficiency with standard PTO quick-connect fittings that allow for easier hookup or switching between attachments, as well as the upgraded LED boom light integrated into the boom that shines directly onto the work area.

Additionally, the updated ViO17-1E and ViO25-6B have been upgraded to a four-point tie system for easier loading and unloading as well as reliable stability during transport.

Kubota U10-5 - 

Kubota kicks off its 50th anniversary year with the introduction of its brand-new U10-5 minimal tail swing compact excavator designed to meet the needs of professionals who require an ultra-nimble machine in the zero- to 1-ton range.

The U10-5 provides flexibility when working in tight spaces with very minimal overhang at 0.6 of an inch over the tracks

The U10-5 extends to a 5 ft. 11 in. digging depth with a bucket breakout force of 2,337 lbs, class-leading capacity in the one-ton space, according to Kubota. 

“We’ve increased the dig depth by three inches over the previous generation, from 5 ft. 8 in. to 5 ft. 11 in,” said Patrick Baker, Kubota construction equipment product manager. “Our dig reach on this machine has increased 12 full inches, so one full foot of added dig reach at ground level from 9 ft. 11. to now 10 ft. 11 in. Not only can we fit into small, confined working sites, we can also reach a little further and get to those places that other excavators can’t.”

Baker continues, “The U10-5 is Kubota’s answer to the rental or professional customer who requires a compact excavator in the zero- to 1-ton range, but in a more compact frame with minimal tail swing to be more nimble and agile than ever before for both residential and commercial work.

The U10-5 provides flexibility when working in tight spaces with very minimal overhang at 0.6 of an inch over the tracks.

“We are very, very close to being true zero tailswing with this U10-5 introduction,” he added. “What that means is this is a great machine for working alongside a curved single lane of traffic or between homes or along the fence line. It’s an excellent excavator for those tough areas to work in.”

Cat 304 and 305 CR - 

Introduced last fall, Caterpillar’s two new mini excavator models complete the Next Gen family of compact diggers with a focus on increased stability.

The 4-tonne Cat 304 and 5-tonne Cat 305 CR Next Generation mini hydraulic excavators have higher bucket breakout forces and deeper standard digging depths for performance that’s improved up to 20% over their E2 series counterparts.

Extended grease intervals and filter service life, combined with common components throughout the line and flat, easy-to-replace side panels, are said to deliver up

The 4-tonne Cat 304 and 5-tonne Cat 305 CR Next Generation mini hydraulic excavators have higher bucket breakout forces and deeper standard digging depths for performance that’s improved up to 20% over their E2 series counterparts

to 10% lower owner and operating costs, according to Caterpillar.

Built with a new reduced radius design, the 304 features a narrow, 66.9-in track width which is 10 in slimmer than the 304 E2, for more versatility and access to confined spaces. While narrower, the new 304 design increases performance, balance and stability of the 4-tonne class model. Its reduced radius allows for greater stability, both 360-degree and when traveling with loads, while its extra counterweight option takes the model to an even higher level of stability.

The new engine on the 5-tonne class Cat 305 CR excavator delivers nearly 9% greater power to increase machine performance. Hydraulic system improvements provide higher breakout forces – 11,061-lbf bucket, 6,362-lbf standard stick and 5,665-lbf long stick – to improve digging efficiency in hard rock applications.

The 305 CR also offers 5.6-in deeper dig depths than the 305 E2, giving it more application flexibility. Its compact radius swing reduces overhang when working to the side, while its 78-in track width and new extra counterweight option help to optimize stability and lift performance in confined spaces.
