HOWO NX 371HP Tractor Head for Sale

Looking for a mainstream heavy‑duty tractor that’s tough, economical, and easy to service? The HOWO NX 371HP Tractor Head hits that sweet spot. With a proven 371 horsepower inline‑six diesel, rugged 6×4 chassis, and driver‑friendly cab, the HOWO NX is purpose‑built for regional haulage, container transport, bulk materials, and construction logistics. This product page gives you a complete, human‑readable breakdown—powertrain, comfort, safety, dimensions, options, and buying tips—so you can decide fast and confidently.

Why Choose HOWO NX 371HP?

• Superior Power, Efficient Driving
  The NX uses a refined 371 HP diesel with high‑pressure fuel injection and optimized combustion. You get strong low‑end torque for starts and climbing plus stable power at cruising speeds. Paired with a 10‑forward / 2‑reverse Sinotruk transmission, the driveline delivers smooth gear shifts, good hill‑climb ability, and solid fuel economy for long‑term cost control.

• Comfortable Driving, Easy Handling
  A four‑point suspended cab and tuned shock absorption system cut vibration and noise on rough roads. The ergonomic air‑suspension driver’s seat (multi‑way adjustable with lumbar support, optional heating) reduces fatigue. A large central display integrates navigation, multimedia, Bluetooth, and vehicle status for stress‑free operation.

• Reliable Safety, Peace of Mind
  The high‑strength steel cab acts as a rigid safety cell. The braking system uses large S‑cam drums (or optional discs), ABS, and EBD for balanced, confident stops—on emergency braking or long downhill stretches. Electronic stability assistance (ESP) and hill‑hold are available to enhance control on mixed terrain.
