Hydraulic bulldozers are bulldozers primarily characterized by hydraulic transmission; simply put, they have a hydraulic torque converter in their transmission system. The entire machine is designed with efficient matching between the engine and the hydraulic torque converter powertrain, tailored to the bulldozer's operating conditions. Combined with a high-performance, highly reliable planetary gearbox, wet steering and braking system, and final drive, it achieves flexible power transmission across the entire speed range, automatic load adaptation, and advantages such as engine stall prevention, large torque reserve, strong power, good fuel economy, and high productivity. Currently, it covers all models from 80 to 900 horsepower and is the mainstream bulldozer model produced and sold globally.

The walking and working device controls can be configured with different structures such as mechanical, pilot, and electronic controls to meet various market demands, providing customers with diverse options while ensuring operational comfort. The driving system features a newly formed, sloped-seal, shock-absorbing cab structure, standard with an integrated internal and external air conditioning system, internal pressurization and dust prevention, wide visibility, and high driving comfort. All major structural components use high-strength castings and forgings, and their box-type design ensures a full lifespan. Based on ergonomic principles, the human-machine interface is humanizedly arranged, and all major maintenance filters are centrally located on one side for easy access. Maintenance parts are readily available, operating costs are low, and service support is timely, ensuring worry-free operation.

Hydraulic-mechanical bulldozers are suitable for earthwork excavation, backfilling, bulldozing, mining, and rock stripping in various engineering projects, making them indispensable construction tools for infrastructure projects such as roads, national defense, water conservancy, and mining.
