This morning, a shipping container bound for Sweden was loaded at the facility of Henan Laierfu Agricultural Machinery Co., Ltd. Inside is a new model of intelligent sweet potato harvester-marking the company's first batch delivery of customized agricultural machinery to a Nordic country. The container has been sealed and is expected to arrive in Skåne Province, southern Sweden, by the end of the month.
This machine is not a standard model; it has been modified to suit local conditions in Sweden. The soil in southern Sweden tends to be sandy loam, the fields are large, and the operating season is short. Furthermore, the client grows organic sweet potatoes, which entails strict requirements regarding skin damage. Laierfu equipped this machine with a fully hydraulic drive and an intelligent contour-following digging system; simply put, the digging blade automatically adjusts its soil entry depth based on the terrain, eliminating the need for frequent manual intervention by the operator. Combined with multi-stage flexible cleaning and separation technology, the measured skin damage rate is kept under 3.2%-nearly half that of the older equipment the client previously used. In terms of harvesting efficiency, field test data from Henan and Shandong provinces shows an improvement of over 35% compared to traditional models.
The machine has obtained EU CE certification, meeting all standards for noise and emissions. The operating interface supports language switching between English, Swedish, and others, and includes a remote maintenance interface-allowing agricultural machinery repair shops in Sweden to connect directly to the diagnostic system without waiting for engineers to fly in from China.
Laierfu's technical lead shared some details about the project. The Swedish client is a sizable local organic sweet potato cooperative with an operating season of only two to three months; once the harvest window closes, they must wait until the following year. Consequently, they were extremely meticulous regarding equipment reliability and ease of maintenance. The process, from initial contact to the final order, involved six months of field adaptability testing. Laierfu dispatched two teams of engineers to inspect the soil quality and terrain and to analyze tractor power take-off (PTO) parameters. Upon their return, 17 specific details were modified-such as recalibrating the digging blade angle, the amplitude of the vibrating screen, and the conveyor belt speed. The client also required the machine to operate reliably in the muddy conditions of the rainy season; in response, Laierfu swapped the tires for wider models with deep treads and upgraded the waterproofing rating for critical chassis components.

Interestingly, the Swedish client had previously relied on German and Dutch brands. They chose Chinese equipment this time primarily because the delivery lead time could be cut by over three months, and the response time for custom modifications was significantly faster. Laierfu possesses over a decade of experience with root crop harvesting machinery, having conducted extensive field testing across the hilly and flat terrains of Henan and Shandong provinces; several design improvements were the result of repeated trial-and-error testing in the domestic market.
Regarding the next steps, the equipment is scheduled to arrive at the port in late July. Laierfu will dispatch an engineer to oversee on-site commissioning for a week and has signed an after-sales service agreement with a local agricultural machinery provider. Furthermore, they plan to establish a spare parts warehouse and a technical training center in Gothenburg, enabling parts replacements to be handled locally in Europe rather than requiring shipments from China.
The project manager offered a pragmatic perspective: "Whether our machines can truly gain a foothold in Swedish fields depends on the big picture-specifically, whether they can get through an entire harvest season without major breakdowns. Signing the contract is just the beginning."
