YBD320Y

YBD320Y Bulldozer Main Features

The appearance of the vehicle is based on optimization design.

Higher engine power reserves efficiency, bigger torque output, lower fuel consumption, while better reliability.

Hydraulically controlled drive, automatically speed regulating and non-stop gear shifting.

3-element, single stage, single phase torque converter for higher efficiency and bigger capacity.

The novel hexahedral cab offers excellent visibility, the powerful ventilation and unparalleled dust-free.

The final drive uses triangle Spline and tip relief, crowned gear drive for enhanced balance and the stability during power transmission, and added life.

New blade is more durable and capacious.

Alarming & monitoring system is efficient and reliable.

Implement controls are piloted to minimize operating effort.
