DX225RB-7 Road Builder

Developed specifically for forestry applications, the DX225RB-7 road builder pairs the recognizable power of DEVELON excavators with specialized forestry features. 

With increased swing torque and improved lifting capacity, the DX225RB-7 can dig and remove trees, brush, and stumps more efficiently, even in rough forest terrain. The fine swing function reduces the amount of swinging when working with heavy loads, resulting in better control and safer operation. And the one-touch power boost, conveniently located on the right-hand joystick, provides a momentary hydraulic boost when you need more lifting power.

The DX225RB-7 features a fully guarded, high-walker undercarriage and upper structure designed to hold up to all-day forestry jobs. Each track includes heavy-duty links with double grouser shoes and full-length track guards.

Road builders are available with a standard-height ROPS cab or optional forestry cab that provides an ideal vantage point for pioneering, offering an excellent view of the work and great all-around visibility. 

The road builder cab includes all the comfort features operators need to stay productive and focused on the job. 

The optional side-entry forestry cab features an optional upgrade to a 32-mm guarded polycarbonate front window and polycarbonate side and rear windows to protect the operator.

An intelligently designed cab makes it easy to focus on your work. You’re surrounded by more foot space, better visibility and automotive-style heating and air conditioning with adjustable airflow. Work comfortably with the standard heated air-suspension seat and simple controls.

Sightlines are critical for operator performance and job site safety, and DEVELON road builders provide the best possible view from inside the cab. 

A standard rotating beacon enhances the road builder’s visibility on busy job sites or when working in low light conditions. Narrow cab pillars provide less obstructed views, standard LED front and rear working lights help identify obstacles, while standard rearview and side view cameras and optional around view monitor (AVM) camera system provide a full view of surroundings.

The Mechatronics Design provides four work modes, auto-idle and machine diagnostics. It includes multiple operating modes and an easy-to-read display monitor. To help save valuable diesel fuel, auto shutdown comes standard. When enabled, it will shut down the machine’s engine when the preset idle time is met. Operators can configure the idle time from 3 to 60 minutes.

A standard multi-function color LCD screen in the cab provides helpful maintenance history, attachment presets and monitoring information, including a fuel consumption gauge. It also displays video from the standard rearview and side view cameras, which gives you improved visibility.

Extended maintenance intervals and easy access to service points increase machine uptime and productivity. Examples include centralized grease points, permanently sealed track pin links that never need greasing, a reversible cooling fan, wide side access doors for cleaning the cooling system, and boom pivot bushings with extended greasing intervals. And a large-capacity engine air precleaner removes more than 99% of airborne particles and extends filter cartridge service life.

DEVELON couplers help you improve versatility and productivity. Utilize buckets along with a thumb to tackle the full range of pioneering tasks, such as clearing felled trees, removing stumps, rough grading and site drainage.

The standard coupler piping ensures that your road builder is attachment-ready and will work with minimal customization.

To reach current emissions standards, the DX225RB-7 incorporates a high-pressure common-rail fuel delivery system as well as cooled exhaust gas recirculation combined with a diesel oxidation catalyst and selective catalyst reduction. Read about our Tier 4 technologies.
