John Deere Construction & Forestry has introduced two new wheeled excavators, the 190D W and the 220D W, featuring Tier III-certified engines and significant increases in horsepower, weight and digging forces over their predecessors.
Both units have fuel-efficient 5.2-L diesel engines rated at 159 hp (118 kW), with the 190D W weighing in at 44,974 lbs. (20,400 kg) and the 220D W at 51,368 lbs. (23,300 kg) when both are equipped with two-piece booms and front and rear outriggers. In addition to its heavier operating weight, the 220D W has a greater dig depth at 20 ft. 8 in. (6.3 m) and more digging forces. The 190D W and 220D W also are available with mono booms for long-distance work and blades for backfilling.
“Whether your job calls for the 19- or 22-metric-ton machine, you can drive from site to site quickly, with a maximum speed topping 23 mph and a lot more maneuverability than a tracked excavator,” said Mark Wall, excavator product marketing manager of John Deere. “The 190D W and 220D W are highly productive in digging ditches, repairing streets and sewers or moving Jersey barriers.”
On the 220D W, wider axles and the additional weight provide more stability and lift capability for quickly moving Jersey barriers.
Power and Control
The 190D W and 220D W have Deere’s Powerwise III engine/hydraulic management system that maximizes engine output and delivers smooth, predictable multifunction operation while saving fuel. One work mode makes it easy to be productive in any application.
The two-speed Powershift transmission shifts smoothly on the go from low to high. Downshifting isn’t a problem either since the transmission will only shift within certain travel-speed parameters — protecting both the operator and the drivetrain, according to the manufacturer.
Hydraulic flow and metering ensure powerful digging force, precise low-effort control and enhanced multi-function operation. Quick, responsive pump activation eliminates any delay in functions.
An intuitive, multi-language LCD monitor provides a wealth of information, including pump flow adjustment, maintenance tracking, onboard diagnostics and service monitoring.
Both units have cabs with more legroom, lower noise levels and ergonomic low-effort controls to fight fatigue and enhance productivity.
The multi-position seat slides together with the control console or independently, ensuring operators can find a comfortable position. The tilt steering wheel is infinitely adjustable for more comfortable operation and it angles up and out of the way for easy entry and exit.
Visibility is improved, too, as a wider expanse of right-hand window glass combined with narrower front cab post and front steering console provide virtually unobstructed all-around visibility. The overhead tinted window hatch also is larger, improving visibility to any obstacles overhead.
Changing hydraulic flow is easy when you use the LCD monitor to observe the flow. You can accommodate a variety of attachment needs, right from the seat. Also, joystick controllers come pre-fitted for auxiliary controls, so it’s easy and inexpensive to add auxiliary hydraulics. The units come standard with low-flow medium-pressure assist hydraulics for operating thumbs, rotators or tilt buckets.
A high-efficiency cooling fan, noise-suppression muffler and isochronous high-idle speed all work to keep the operator’s environment quiet. Silicone-filled mounts effectively isolate operators from noise and vibration.
The cab also features an AM/FM radio, an automatic, high-capacity climate-control system, and a convenient 12-volt port for cell phone charging. There’s also a space for a lunch box, cup holders, and even a hot/cold box that keeps refreshments at the right temperature.
Dependability and Serviceability
John Deere wheeled excavators retain all the dependability and serviceability features of their D-Series siblings for maximum uptime and low daily operating costs.
Rigid, reinforced D-channel side frames resist impacts, providing maximum cab and component protection. Welded bulkheads within the boom resist torsional stress for long-term durability. Heavy-duty covers on the oversize outriggers help protect the hydraulic cylinders from damage.
Tungsten-carbide coating creates a wear-resistant surface to protect the bucket-to-arm joint. Powdered metal oil-impregnated bushings enhance durability and extend grease intervals to 500 hours for the arm-and-boom joint and 100 hours for the bucket joint. Reinforced resin thrust plates increase lube intervals to 500 hours.
Large service doors provide wide-open access to daily checkpoints. Easy-access, remote-mount oil and fuel filters can be changed without crawling under the machine or removing access panels, reducing service time. Extended service intervals let you work longer — and earn more — between changes.
