SD6G推土机使用上柴公司引进美国卡特技术生产的C6121型发动机，具有扭矩储备系数大，抗过载能力强的特点；变矩器为外分流综合式液力机械变矩器具有效率高、高效区宽的特点。转向、制动采用连动形式，制动系统为液压助力；终传动系统齿轮采用大变位设计，承载能力高、使用寿命长，同时终传动采用轴承游隙免调整结构，维修方便；
SD6G bulldozer is 160 horsepower track-type dozer with hydraulic direct drive, semi-rigid suspended and hydraulic controls. It is equipped with Shangchai C6121 diesel engine manufactured under Caterpillar license. The engine has the characteristics of big torque reserve coefficient and capacity against over-load. The torque converter is a hydro-mechanical converter whose power is divided outside, which has the characteristics of wide high efficiency range. Steering and braking can be controlled with the same control lever. Braking system utilizes hydraulic boosting structure, which is convenient and labor-saving. The final drive gear has the characteristics of large displacement coefficient value. This kind of design raises bearing capacity and prolongs the useful time. The final drive also utilizes the structure that its bearing clearance is free of adjustment, which is convenient for service. The equalizer bar utilizes free lubricating structure to decrease service cost.
