Model 3688 (4LZ‑3) is a harvesting machine from the Chinese manufacturer Shifeng. It is produced at the Gaotang plant in Shandong province and runs on diesel fuel. The machine belongs to the harvesting machinery group and is identified as 3688 (4LZ‑3).
The engine delivers 125 hp (93 kW), which enables the machine to perform typical harvesting tasks such as cutting, threshing and transporting grain. Diesel propulsion provides the torque characteristics required for steady operation under varying field conditions. A power output of 125 hp allows the drive of harvesting implements covering wide working widths, while the 93 kW rating supplies sufficient energy for auxiliary equipment.
With its size, the 3688 (4LZ‑3) is suited for use in medium to large agricultural operations that conduct harvesting on extensive fields. Its design is intended to operate reliably both under normal harvesting conditions and in more demanding situations, such as when handling higher yields.

This page gathers the Shifeng harvesting machines 3000A, 3688 (4LZ-3) and 6158 that the register could not assign to a named range. Shifeng is an agricultural machinery maker from Shandong in China; the 4LZ-3 suffix on the 3688 model follows the type logic used in China for self-propelled grain combines, where the digits denote the design and size class.

The register lists here 3 versions with 57 to 93 kW, or 76 to 125 hp; all three run on diesel.
Shifeng is among the Chinese agricultural machinery makers that, alongside tractors, have since the 2000s increasingly offered combine harvesters for the domestic market and for export to other Asian and African countries, competing there on price with established international brands.
On self-propelled combines of this size class, the header sits as an interchangeable attachment on a feeder house that carries the cut stalks to the threshing drum; there the drum, together with the straw walkers, separates the grain mechanically from straw and chaff, before the sieve deck and cleaning fan sort out the remainder. The cleaned grain collects in the grain tank and is discharged through an unloading auger beside the machine, while chopped straw is spread across the field directly behind the machine.
When buying used, what counts on these combines is the condition of the threshing drum, sieves and chopper, the tightness of the hydraulics, and the compression and condition of the diesel engine's injection pump; since Shifeng machines are not represented everywhere outside China, it is worth checking local parts availability before buying.

The Shifeng 3688 (4LZ-3) delivers 125 hp.
What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
