Features and benefits
Get consistent, reliable grades
A long wheelbase and heavy operating weight allow the GD955-7 to achieve high blade downforce pressures at more aggressive moldboard angles for improved penetration and material flow in hard-packed road surface applications.
Work effectively in confined areas
The large 27-degree articulation angle allows a tight turning radius and provides maneuverability for narrow haul road applications in confined spaces and around obstacles.
Strong and durable structure
Redesigned front and rear frames help withstand bending forces and torsional loads, promoting reduced life-cycle costs and a longer service life.
Make maintenance easy
A newly adopted bearing-type circle assembly eliminates wear plates and the need for frequent play adjustments to help minimize downtime. Coupled with an auto-lubrication system, this helps to reduce maintenance times by up to 21%*.
Optimize your machine's performance
Perform routine checks, inspections and repairs conveniently with a centrally located, ground-level service center. Regular maintenance helps promote your machine's uptime, while easy access streamlines maintenance workflow.
Flexible for all operator levels
Enhance production with the efficiency of a direct-drive transmission and the controllability of a torque converter drive transmission. Perfect for trained operators of all experience levels and applicable to a wide variety of tasks, including maintaining and building haul roads
Stay comfortable while working
Operators can work comfortably in the cab throughout the day with an air-suspension, heated and ventilated seat that helps dampen mechanical vibrations. Operators can also electronically or manually adjust the control lever console height to their preference.
Precise control efficient operation
Controls within easy reach allow operators to quickly adjust to changing grading conditions or terrain. This helps optimize performance, while fingertip controls make for a more ergonomic and comfortable working environment.
Facilitating work site visibility
The hexangular cab and integrated control console layout allow for improved visibility to the moldboard. Strategically placed mirrors enhance visibility, while KomVision provides a bird’s-eye view around the vehicle on an in-cab monitor. *Compared to the previous model
