● Description

●A CUMMINS NTA855-C360S10 engine gives you more power and reliability you need. With exhaust turbocharger, it can still work normally at altitude of 4,300 meters.

●The highly reliable power shift transmission, stable torque converter and the two- stage straight-tooth structure final drive transmit power efficiently.

●With independent engine cooling water tank, chassis oil cooler, water and air intercooler provides excellent cooling performance and simple maintenance operation to ensure continuous operation of the machine.

●The final drive is driven low and provides more powerful driving force and efficient gradeability.

●The standard straight tit blade features powerful cutting force and the heavy single- shank ripper can be equipped for the ripping of clay and frozen earth, featuring high working efficiency and super-strong penetrating force.
