Experience the SDLG Grader G9138 trust and reliability. Equipped with environmentally-friendly CEV-IV Engines, ZF Transmissions, and SDLG axles, it combines power, speed, and maneuverability for enhanced productivity. Boost your profitability with this state-of-the-art grader that ensures optimal performance and higher profitability.
CEV-IV Engine: The SDLG G9138H features a CEV-IV certified engine known for low fuel consumption and emissions, meeting ARAI standards. It offers operator comfort and performance with reduced cabin noise levels. The HP controls allow operators to select power levels according to job requirements, while the turbocharged, low-emission engine and electronic control unit optimize fuel usage in all conditions. Cruise control is standard for SDLG Graders.
Transmission: The ZF electronically controlled ZF6WG158 fully automatic transmission with manual override ensures fast and efficient work cycles. With 6 forward and 3 reverse gears, it enables efficient grading operations.
Axles: SDLG axles are an integral part of the drive train, incorporating top-class technology and performance. They provide superior bearing force, machine stability, and reliability.
Large Drawbar Pull: Powered by a CEV-IV engine with an output power of 148HP and high torque, coupled with an operating weight of 13,000KG, the G9138H delivers high drawbar pull, making it perfect for heavy-duty grading jobs.
Hydraulic System: The patented hydraulic control mechanism enhances operator friendliness, productivity, and reliability. The working pump, matched with the engine power, significantly increases production efficiency. Improved seal structure ensures enhanced sealing reliability throughout the hydraulic system.
High Stability: The SDLG grader ensures excellent weight distribution, with significant weight on the rear wheels (9,400KG) for power and traction, and less weight on the front axle (3,600KG) for control. This balanced weight distribution eliminates the need for additional counterweights, while the large blade force ensures easy penetration and reduces the number of passes.
Articulated Frame: The 25-degree articulated frame with a minimum turning radius of 6.5 meters enables superior maneuverability. The straight frame with articulation ensures precise grading, while the articulation indicator in the cabin assists the operator in maintaining a straight line.
Comfortable Workplace with Excellent Visibility: SDLG prioritizes operator comfort and provides a ROPS/FOPS certified air-conditioned cabin that is ergonomically designed for high visibility and enhanced productivity.
Drawbar, Circle, and Moldboard: The excellent drawbar design allows the addition of an optional mid-mount scarifier without compromising blade positioning. The circle is built to withstand high-stress loads, and the 12-feet moldboard with mechanically controlled tilt enables efficient grading in various soil conditions. The blade can be positioned at desired bank cutting angles of up to 90 degrees on either side. High blade rotation speeds facilitate faster production and reduce the number of passes.
Front Mounted Utility Dozer Blade: Optional utility dozer blades are available for added versatility.
