Wuzheng – other models: the collective page of Chinese compact tractors outside the named ranges, from the WZ200 to the WZ504, 15 to 41 kW, diesel engines from Weifang

This page gathers the Wuzheng tractors the register could not assign to a named range. Wuzheng is a corporate group from Weifang in China's Shandong province, known chiefly for three-wheeled utility vehicles and simple agricultural tractors for the Chinese domestic market and export to Africa, Southeast Asia and Latin America. The WZ types listed here are small, rugged compact tractors; the number after WZ gives roughly the power class (WZ200 at the lower, WZ504 at the upper end of the range), the letter X or A at the end marks construction or equipment variants within a power class.

The register lists here 17 versions with 15 to 41 kW, that is 20 to 55 hp; all run on diesel engines.

With the WZ tractors, Wuzheng serves the lower price segment of simple compact tractors in demand across much of Africa and Southeast Asia among smallholders and for transport around the farmyard; there the brand competes with other Chinese makers in the same size class.

On used tractors, operating hours, the condition of the injection pump and radiator, the tightness of the hydraulics, the condition of the clutch and mechanical gearbox, and rust on the chassis and mudguards count; outside China, parts are usually only available regionally through importers or parts dealers.

What to check before buying

  • Check the hour meter against the service records — a replaced instrument is the most common gap.

  • Load the hydraulics and watch for sag.
  • Ask about parts availability for this build year — the running costs hang on it.
