Product Description

High-performance Used HOWO Tractor Head 

The HOWO 371HP Tractor Head (6x4 Chassis, Used) is a heavy-duty prime mover designed for demanding freight and logistics operations. Built on a 6x4 drivetrain, it offers superior traction, load-bearing capacity, and stability, making it ideal for long-haul transport, mining, and construction applications.

Key Configurations

Engine: 

WD615.47 diesel engine (371HP / 273kW) with 1350 Nm torque (1100-1600 RPM), ensuring strong pulling power for heavy trailers.

Euro II/Euro III emissions—suitable for regions with less stringent regulations.

Robust 6x4 Drivetrain: 

Front drive axle & ST16 double-reduction rear axles (5.73 ratio) for excellent off-road and on-road traction.

HW19710 10-speed manual transmission (some models may have 12-speed) for smooth gear shifts under heavy loads.

Durable & Functional Cabin:

HW76 flat-roof cab with sleeper berth & manual AC—functional for long-haul drivers but may show wear in a used model.

ZF8118 hydraulic power steering (German technology) for precise handling.

Heavy-Duty Build (Pre-Owned Inspection Tips):

12.00R22.5 tires (10 unit)—check tread depth and sidewall condition.

400L fuel tank—inspect for rust or leaks.

Max towing capacity: ~34,720kg—confirm structural integrity (no frame cracks or welding repairs).
