Shantui New Road Machinery Big Tractor Wheel Motor Grader (SG21-3)

Power System

It’s powered by Dongfeng Cummins 6CTAA8.3-C215 China-II compliant inline, 4-stroke, direct injection, water-cooled, and turbocharged and intercooled diesel engine, featuring compact structure, stable performances, and high efficiency and energy-saving.

The high torque reserve enables the machine to output stable power under severe working conditions and meet your working needs.

Driving/Riding Environment

The high-grade full-sealed luxury cab with full visual field and the high-efficiency shock-absorbing seat maximize the operating comfort.

The cab and the main frame are connected by shock absorber to ensure the operating safety and reliability.

Working adaptability

With 6 forward gears and 3 reverse gears, the electro-hydraulically controlled power shift transmission can select the optimal gear based on the working road condition to realize the best match between traveling and operation.

The integral three-segment drive axle is built internally with imported no-spin automatic limited slip differential to guarantee stable and reliable drive.

The balance box is capable of 15° angular swing in vertical direction and the heavy-duty roller chain drive guarantees better terrain adaptability of the machine. It can meet the normal operations under special road conditions, featuring stable power output and strong drive force.
