    Engine Power: 162kW/2200Meet the national three emissions
    Total Weight: 17000kg
    Blade width: 3660/3965/4270mm

  • Power System

    ● SG21-C6 uses Weichai WP7 diesel engine with China III emission. / SG21-B6 uses Cummins 6CTAA8.3-C215 diesel engine with China II emission.
    ● It has compact structure, stable performance, high efficiency and energy saving.
    ● Large torque reserve ensures the stable output power of the machine under severe working conditions to meet your operational needs.

  • Driving/ Riding Environment

    ● Industry first without Acolumn front F&R Cab, full-view driving environment system, good follow-up, greatly improving work comfort and work efficiency;
    ● The new whole machine shock absorption and noise reduction control technology, the noise value near the driver’s ears can be reduced to 76dB, driving is more comfortable;
    ● High-power heating and cooling air conditioner, three-dimensional air duct, with the function of changing fresh air and maintaining positive pressure in the cab.

  • Working Adaptability

    ● Yes Equipped with load-sensing technology, temperature-controlled fan, blade obstacle avoidance and floating and other functions, and meet customer’s personalized customization requirements; Slewing bearing structure working device, the ring gear rotates smoothly, the gap is free of adjustment, and the working accuracy is high;
    ● Front bulldozer, rear ripper, middle ripper, front ripper,4270mm/3965mm/3660mmL ength blade to meet the special needs of working conditions.

  • Operating Performance

    ● It has larger traction force in the same type of motor grader, and is more efficient than the same type of products;
    ● International leading control technology, lighter control force and short stroke; electronically controlled hand and foot dual throttle control to achieve one-button constant speed; electronically controlled walking control, smooth gear shifting, improved operating comfort, and reduced labor intensity;
    ● The three-stage adjustable console is adopted, which has a richer spatial posture and meets the needs of operators with different weights and heights.

  • Easy Maintenances

    ● Large-capacity fuel tank and ground refueling, meet the 16h Continuous heavy-load operation saves time and cost, while improving the convenience of maintenance and creating greater value for users;
    ● Wear-resistant double slide rails and large-width wear-resistant blades increase blade life 100% ;
    ● No-climb height lubrication technology eliminates high lubrication points, realizes ground lubrication of the whole machine, and reduces the number of lubrication points20%at the same time refueling, oil draining design, maintenance is more convenient.
