Designed for Power

With impressive digging and high tractive power, the DEVELON DL420-7 wheel loader excels in tough applications. It's designed to take on a wide range of material handling tasks, from loading and transporting granular material (such as sand and gravel) to large general construction applications.

Powered by a powerful Tier 4 diesel engine, it can penetrate tough materials, tilt and lift with ease, and carry more in every cycle. Performance features include a powershift transmission with optimized hydraulic pumps, multiple power modes, Z-bar lift arm, return to dig, and limited slip differentials on both front and rear axles.

Measurable Productivity

The high-lift option offers additional lift height and reach. Added material strengthens each section of the rugged box frame for better balance and improved lifting capacity.

An efficient cooling system features wider radiator fin spacing and a reversible fan to quickly clear debris.

The optional Load Isolation System improves vehicle stability while moving. An optional quick coupler allows you to quickly change many non-hydraulic attachments without leaving your seat. The optional DEVELON Smart Load weighing system is ideal for job applications that require accurate information about material weight in the bucket.

Comfort and Visibility

The redesigned cab features a better view of the work thanks to 14% more glass, a full glass door, larger mirrors, optional work lights and a standard rearview camera.

Controls are within easy reach and more intuitive to use. The DEVELON Smart Touch screen displays all important settings and information, including the view from the rearview camera. From the screen, operators can monitor critical machine functions and control machine settings, heating and cooling, the DEVELON Smart Guidance System and more.

The exclusive Standard Transparent Bucket option provides a supplemental visual perspective by allowing operators to “see-through” the bucket from an in-cab display.

The DEVELON Smart Key fob unlocks the cab and allows push-button engine starts.

Easy Maintenance

It’s easier to stay on top of maintenance with the DL420-7. Centralized lubrication points, plus easy component access and fluid-level checks, make daily checks more convenient.

The available automatic lubrication system offers improved machine reliability.

DEVELON Fleet Management, a powerful equipment diagnostic tool, monitors the health, location and productivity of your DEVELON equipment from a user-friendly mobile app and website. You can quickly and easily check machine location, fleet status, operating hours, error codes, fuel usage, engine idle vs. work time, engine and hydraulic oil temperature and various other data points. And it allows your dealer to offer more proactive service to help maximize machine uptime.

Machine Efficiency

The latest technologies work to improve fuel efficiency. Situation Awareness Technology (SAT) automatically adjusts the engine output in real-time to the needs of the drivetrain and hydraulics to help save fuel without compromising performance.

The standard auto-idle feature reduces engine rpm when the steering wheel or joystick isn’t being used, and auto-shutdown turns off the engine after a set amount of time idling.

To comply with Tier 4 emissions standards, the DL420-7 incorporates a high-pressure common-rail (HPCR) fuel delivery system as well as cooled exhaust gas recirculation (CEGR), combined with a diesel oxidation catalyst (DOC) and selective catalyst reduction (SCR) with diesel exhaust fluid (DEF).
