DX300RB-7 Road Builder | Develon

Purpose-Built for Forestry Applications

The Develon DX300RB-7 road builder is engineered specifically for demanding forestry operations, combining proven excavator performance with specialized features for pioneering, land clearing, and timber management. Increased tractive force allows the machine to travel confidently across uneven or soft terrain while efficiently pushing down trees. A fully guarded upper structure and high-walker undercarriage are built to withstand harsh forestry environments, while heavy-duty track links, double grouser shoes, rock guards, and full-length track guiding guards provide exceptional durability throughout long workdays.

Cab Options for Safety and Visibility

The DX300RB-7 is available with either a standard-height ROPS cab or an optional forestry cab designed to maximize operator protection and visibility. The road builder cab provides an excellent vantage point for pioneering operations while offering outstanding all-around visibility and operator comfort. For more demanding forestry applications, the optional side-entry forestry cab features a guarded polycarbonate front window, polycarbonate side and rear windows, and a rear secondary exit for enhanced operator safety in challenging environments.

Operator Comfort in Demanding Conditions

Designed to keep operators comfortable throughout long workdays, the DX300RB-7 features a spacious cab with increased foot room, excellent visibility, and automatic climate control with adjustable airflow. A heated and cooled air-suspension seat, ergonomic controls, and an intuitive operator layout help reduce fatigue while maintaining productivity in tough working conditions.

Enhanced Visibility for Safer Operation

Excellent visibility is essential for both productivity and jobsite safety. The DX300RB-7 features narrow cab pillars to improve sightlines, along with standard rearview and side-mounted cameras that provide greater awareness around the machine. An optional Around View Monitor (AVM) system offers a comprehensive view of the work area, while a standard rotating beacon increases machine visibility during low-light operation and on active jobsites.

Intelligent Power and Machine Control

The DX300RB-7 utilizes an advanced Mechatronics system that offers four selectable work modes, automatic idle, onboard diagnostics, and simplified machine management through an easy-to-read display. Standard auto shutdown helps reduce unnecessary fuel consumption by automatically shutting off the engine after a preset idle period, while the color LCD monitor displays machine information, maintenance data, fuel consumption, and live camera feeds for improved operator awareness.

Built for Maximum Uptime

Extended maintenance intervals and simplified service access help keep the DX300RB-7 working longer with less downtime. Centralized grease points, wide side access doors for cooling system maintenance, extended-life boom pivot bushings, and a high-capacity engine air precleaner that removes more than 99 percent of airborne particles all contribute to lower maintenance requirements. MY DEVELON fleet management further helps monitor machine health, maintenance schedules, and operating performance to reduce ownership costs.

Versatility for Forestry and Land Clearing

The DX300RB-7 is designed to support a wide range of forestry and site development tasks. Standard coupler piping allows quick integration of compatible attachments, while DEVELON couplers make it easy to switch between buckets, thumbs, and other work tools. This versatility enables operators to efficiently clear felled trees, remove stumps, rough grade terrain, improve drainage, and complete a variety of pioneering applications with a single machine.

Efficient Tier 4 Performance

The DX300RB-7 meets Tier 4 emissions standards using an advanced high-pressure common-rail fuel system combined with cooled exhaust gas recirculation (EGR), a diesel oxidation catalyst (DOC), and selective catalytic reduction (SCR). This emissions system delivers powerful, fuel-efficient performance while meeting today's stringent environmental regulations.
