G9290

Product Introduction

1. The SDLG new ROPS/FOPS cab offers excellent visibility and operator comfort, enhancing efficiency and performance with its enhanced design.

2. The SDLG SD130B Stage III diesel engine provides high torque at low revs and outstanding fuel efficiency with Variable Horse Power technology.

3. The cooling package features an operator-controlled reversible fan for efficient temperature regulation.

4. Maintenance is simplified with large, openable rear doors providing easy access.

5. The SDLG HTE840S transmission, designed by Volvo, includes 8 forward speeds, 4 reverse speeds, and a specialized grader transmission.

6. The heavy-duty chain-driven tandem features a differential lock on the rear axle and durable tandem bearings.

7. The SDLG dual cylinder turning circle and wide-stance lift cylinders ensure optimal grading performance and stability, reducing rework and improving surface finish.

8. The variable displacement axial piston pump feeds oil to a proportional demand closed-center load sensing main control valve, offering precise blade control.

9. The 14-foot moldboard blade provides extensive mobility with rotation, side-shifting, and tilting capabilities for effective banking and ditching.

10. The heavy-duty front axle's mobility helps maintain a level moldboard for a superior finished grade.

11. The durable frame is factory-prepared to accommodate all types of attachments.
