2300XPC GPL9762 7

Are you in search of a machine that combines smooth accuracy with operator-friendly features? This grader, powered by a distinctive dual-mode transmission, not only provides enhanced job site visibility but also serves as an exceptional tool for operators striving for surface precision.

Key features include:

  • Exceptional visibility, ensuring operators have a clear view of the job site for precise operation.
  • Smooth power delivery and optimized control, contributing to overall operational efficiency.
  • High-flow hydraulics equipped with on-demand Closed Load Sensing System (CLSS) valves, enhancing operator efficiency.
  • Dual engine power modes, offering increased fuel efficiency of up to 15% when compared to the GD655-5 model.

Product Features and benefits:

Innovative Dual-Mode Powershift Transmission: Experience superior control, finesse, and traction with the exclusive dual-mode transmission and torque-converter. This industry-first technology, coupled with anti-stall features, ensures steady efficiency for fine finish grading or precise cutting around obstacles.

Fuel Efficiency Power Modes: Choose between two selectable power settings for efficient operation. Eco mode enhances fuel efficiency during fine finish grading or light-duty road maintenance, while power mode tackles heavy pushing or high-demand tasks with optimal power.

Blade Lift Accumulators for Protection: Standard blade lift accumulators safeguard the moldboard, drawbar, and blade circle from damage. These selectable function blade accumulators absorb impacts, providing protection if the blade edge encounters immobile objects like manholes, boulders, or railroad crossings.

Operator Comfort for Long Workdays: Enhance operator comfort during long workdays with the standard air suspension seat. This seat adjusts to the operator’s weight and minimizes vibrations from the machine, reducing fatigue.

CLSS Constant Implement Speed Hydraulics: Benefit from a high-performance hydraulic system that ensures responsive control and smooth, constant speed. The closed-center load-sensing system allows multiple circuits to operate simultaneously, independent of engine speed.

Hexangular Cab for Increased Visibility: Improve visibility with a commanding view of the job site. The hexangular, low-profile cab layout offers a wide field of vision, increasing visibility of both front and rear work equipment.

Rearview Camera for Enhanced Safety: Ensure your operator can monitor surroundings effectively with the standard rearview monitor system and a dedicated display featuring custom settings. This guarantees that the main monitor consistently shows crucial machine information.

Hydraulic-Driven Cooling Fan for Efficiency: Run the fan only when necessary, enhancing efficiency and power. The hydraulic cooling fan adjusts its speed based on engine load and temperature, optimizing performance.

Actionable Insights with Komtrax: Stay informed about your machine’s productivity with the latest Komtrax system. Receive remote alerts on service needs, operating history, faults, and fuel usage reports, accessible by authorized users.
