Howo A7 420 Tractor Head

This Howo A7 420 tractor head delivers 420 hp from a SINOTRUK D12.42-20 diesel (also available with WD615.47 371 hp) through a 10-speed gearbox with 2 reverse gears. The 6x4 chassis with HF9 front and HC16 rear axles hauls 50-70 tons on a 400+1000L dual fuel tank setup. Available in 4x2, 6x4, and 8x4 configurations, left-hand or right-hand drive, with single or double sleeper cab. 8,700 x 2,500 x 3,450 mm, 25,000 kg GVW, mechanical suspension, CCC certified.

420 hp D12.42-20 or 371 hp WD615.47

Two SINOTRUK engine options drive the Howo A7 tractor head: the D12.42-20 at 420 hp for heavy long-haul routes with steep grades, or the WD615.47 at 371 hp for regional distribution where fuel economy matters more than peak torque. Both engines pair with a 10-forward 2-reverse manual gearbox. The tractor head is designed for fuel-saving operations with low maintenance costs across all variants.

400+1,000 Litre Dual Fuel Tanks

The Howo A7 420 tractor head carries a combined 1,400 litres of diesel across its dual tank setup - a 400-litre main tank and a 1,000-litre auxiliary tank. That fuel range supports regional routes across Africa, the Middle East, and Southeast Asia without stopping for refuelling, keeping the tractor truck head rolling while competitors' trucks queue at the pump.

Mining and Quarry Haulage

The Howo A7 tractor head pulls loaded dump trailers and bulk material semi-trailers carrying bauxite, manganese, gold ore, coal, and uranium out of open-pit mines. The 6x4 configuration with HF9-HC16 axles delivers driven traction on unpaved mine roads, while the 50-70 ton towing capacity matches the output of standard excavators and wheel loaders in fleet operations.

Construction Engineering

Transports sand, stone, and construction waste on tipper semi-trailers and flatbed trailers between quarries, concrete batching plants, and infrastructure project sites. The tractor head drops a loaded trailer at the job site, hooks an empty one, and returns - keeping the trailer working while the tractor truck head stays on the move.

Long-Distance Logistics

For bulk cargo transport - food-grade containers, general freight, and industrial goods - the Howo A7 420 tractor head pairs with dry-van and container chassis semi-trailers. The 1,400-litre dual fuel tank setup enables cross-border freight routes without refuelling stops that add hours to delivery schedules and eat into the per-tonne margin on long-haul contracts.

Drop-and-Hook Fleet Operations

The tractor head is designed for trailer-swap efficiency: deliver a loaded semi-trailer to the destination, uncouple, and pick up a pre-loaded trailer for the return leg. With the Howo A7's fuel economy and reliable mechanical suspension, fleet operators running drop-and-hook cycles maximise tractor utilisation - the truck earns revenue while driving, not sitting idle while a trailer is being loaded or unloaded.
