Metalfor 2635: New South American Combine Rotor Threshing System
- Metalfor has introduced the 2635 combine harvester equipped with a rotor threshing system for the South American agricultural market, according to reporting from GÉPmax.
- The 2635 model utilizes a rotor threshing system rather than a conventional straw-walker mechanism.
- According to GÉPmax, the primary feature of the 2635 is its rotor-based threshing system.
Metalfor has introduced the 2635 combine harvester equipped with a rotor threshing system for the South American agricultural market, according to reporting from GÉPmax. The new model is designed to handle the specific harvesting requirements of the region’s large-scale farming operations.
The 2635 model utilizes a rotor threshing system rather than a conventional straw-walker mechanism. This technical configuration is typically used to increase throughput and improve grain separation efficiency, particularly in high-yield environments or varying moisture conditions common in South American crops.
How does the rotor system function in the Metalfor 2635?
According to GÉPmax, the primary feature of the 2635 is its rotor-based threshing system. Unlike traditional combines that use a cylinder and concave followed by shaking straw walkers, rotor systems move the crop material axially through a rotating drum.

This design generally allows for a higher volume of material to be processed per hour and reduces the likelihood of grain damage. These specifications are intended to meet the demands of South American agribusinesses that manage extensive acreage of soy, corn, and wheat.
Why is this release significant for the South American market?
The introduction of the 2635 positions Metalfor as a regional provider of high-capacity harvesting technology. The South American agricultural sector is characterized by massive monocultures and a high reliance on mechanized efficiency to maintain global export competitiveness.
By offering a rotor system, Metalfor competes with global machinery manufacturers that have historically dominated the high-capacity segment. The availability of regionally tailored machinery can reduce logistics costs and improve access to maintenance and parts for farmers in Brazil and neighboring countries.
What is the business context for Metalfor?
Metalfor operates within a competitive landscape of agricultural equipment manufacturing in South America. The company’s strategy with the 2635 focuses on providing specialized technology that addresses the specific soil and crop conditions of the Southern Hemisphere.
The shift toward rotor technology reflects a broader industry trend in the region to move away from smaller, conventional machines toward high-capacity equipment that can operate in shorter harvest windows. This transition is driven by the need to minimize crop loss and maximize the speed of the harvest cycle.
