Collectively, these features are aimed at increasing efficiency, reducing life-cycle costs and improving the consistency of surface quality on projects.

Operational performance and productivity

Productivity with a grader such as the GR3505 depends on several variables: ground conditions, blade setup, operator proficiency, and the integration of technologies like GPS grade control. In favorable conditions, a 350-class grader can achieve high material displacement rates when used in tandem with dozers, scrapers or loaders. Key operational considerations include:

• Using the correct moldboard angle and cross-slope to minimize recutting and mixing of unsuitable material.
• Maintaining consistent engine speed and torque for cutting through dense layers without stalling.
• Optimizing tire selection and pressure to match load and surface conditions for traction and flotation.
• Employing grade-control systems for finish passes to reduce rework and survey time.

Fuel consumption is influenced by engine technology, load cycles and duty. For reference, heavy graders in this horsepower class typically consume in the range of 18–35 liters per hour under normal to heavy load—exact consumption will vary. The GR3505 is designed to be competitive in fuel economy through efficient hydraulics and engine tuning, and optional technologies can further reduce fuel use by minimizing unnecessary idling and enabling more precise passes.

Maintenance, reliability and serviceability

Long-term operating cost is strongly affected by maintenance strategy and the accessibility of spare parts. The GR3505’s design typically focuses on:

• Accessible daily service points: easy access to filters, batteries, fluid reservoirs and key inspection areas.
• Robust wear components: heavy-duty cutting edges, replaceable side bits, and durable circle teeth to lower replacement frequency.
• Structured maintenance intervals: recommended service schedules for engine, transmission and hydraulic systems to prevent unplanned downtime.
• Dealer support and parts network: XCMG’s international presence and dealer network can supply parts and technical assistance in many regions; availability may vary by country.

Following manufacturer guidelines for oil, filter and hydraulic fluid changes, as well as monitoring component wear, will maximize service life and preserve resale value. Training operators in proper machine use—avoiding excessive side loading of the blade, preventing material build-up on moving components, and using the correct gear ranges—also extends component life.

Safety and environmental considerations

Modern graders incorporate many safety features to protect operators and jobsite personnel. Expected safety aspects for the GR3505 include:
