CLAAS Expands the SUNSPEED Header Lineup: Up to 11.90 m Working Width for Row-Independent Sunflower Harvesting

CLAAS is expanding its SUNSPEED sunflower header lineup with three new models offering working widths of 7.50, 9.40 and 11.90 m. The main technical idea behind the update is sunflower harvesting regardless of sowing direction and row spacing. For farms and contractors working across different regions, hybrids, plant heights and sowing patterns, this is not merely another extension of the model range, but a response to a real challenge in field practice.

Sunflower remains one of the crops where harvesting losses can depend significantly not only on combine settings, but also on header design. This becomes especially noticeable in uneven stands, with different plant heights, different head diameters, over-dried stalks or changing travel direction relative to the rows. That is why header manufacturers are paying more attention to versatility and adaptability. The new SUNSPEED from CLAAS is built around the idea that a header should work not for one fixed row spacing, but for the actual condition of the field.

What Has Changed in the SUNSPEED Lineup

The updated SUNSPEED series now includes three working widths: 7.50 m, 9.40 m and 11.90 m. The widest version effectively brings the lineup into the high daily output segment, where not only cutting width matters, but also the header’s ability to work steadily at speed without a sharp increase in losses.

The key feature is row-independent harvesting. Thanks to the specific shape of the feeding elements, which CLAAS describes as “shuttles”, the header can work with different sowing patterns and different stalk thicknesses. This is especially important for contractors who move from one field to another during the season and often do not have identical sowing conditions. In such situations, a classic dependence on row spacing can limit output and, in some cases, increase the risk of losses.

How the Row-Independent Harvesting Concept Works

In sunflower harvesting, the task is not simply to cut the plant, but to separate the sunflower head as cleanly as possible, without feeding excessive stalk material into the threshing system. The more unnecessary biomass enters the combine, the greater the load on threshing and cleaning. This can affect fuel consumption, cleaning quality, throughput and wear on working components.

SUNSPEED is designed so that mainly sunflower heads enter the combine. The feeding elements pick up the plants, while adjustable guides and the header design direct the heads toward the reel, after which the cut is made. This principle helps reduce stalk intake into the combine and therefore relieves the threshing and cleaning systems.

Official CLAAS product information emphasizes that the functional principle of SUNSPEED helps reduce the load on the threshing and cleaning systems. For a farm, this means not an abstract convenience, but a practical effect: a more stable crop flow, potentially lower load on combine assemblies and better adaptation to different harvesting conditions.

Tool-Free Adjustment: Why It Matters in the Field

One important technical detail is the 1.60 m feeding shuttles with adjustable spacing. According to official CLAAS data, the distance between elements can be continuously adjusted from 4.0 to 6.5 cm depending on stalk length and head size. The adjustment is performed without tools: the operator loosens the screw at the end of the element and moves the plate into the required position.

In real field conditions, this matters greatly. Even within one season, sunflower can vary significantly: one hybrid forms a larger head, another has a thinner or thicker stalk; a field may include zones with better and poorer moisture supply; plants at field edges often differ from those in the central area. If the header adapts quickly to such conditions, the operator gains more control over losses and feeding quality.

Reel, Auger and Cab-Based Control

Another important part of the update is reel operation. Reel speed and height can be adjusted hydraulically while driving. For LEXION and TRION combines, SUNSPEED functions are integrated into the CEBIS system, and control can be carried out via the CMOTION multifunction lever. This allows the operator to respond to changing conditions without stopping, which is especially relevant in uneven stands.

Reinforced reel elements clear the gaps between the feeding elements and guide the heads toward the auger. According to CLAAS, the auger is made of 5 mm sheet steel. Its task is to feed the cut material evenly to the feeder housing. In the central part of the auger, fingers can be replaced when worn, and their number and spacing can be adapted to working conditions.

The adjustable reel cover bends the plants forward, gently presses the head downward and helps make a precise cut without taking in excessive stalk material. This is particularly important when the crop is over-mature, the heads have different moisture levels or the field is uneven in plant height.

Why the 11.90 m Width Has Practical Significance

A working width of 11.90 m is not just a marketing figure. For large farms and service contractors, it means potentially higher daily output, fewer field passes and better utilization of a high-capacity combine. But in sunflower harvesting, header width makes sense only when the design can handle crop flow consistently and does not create excessive losses.

That is why SUNSPEED focuses not only on increased width, but also on adjustment, controllability and combine integration. A wide header without precise adjustment can quickly become a source of problems. A wide header with adaptive geometry, cab-based control and proper crop feeding is already a tool for high productivity in demanding conditions.

Who Will Benefit Most from This Equipment

The new SUNSPEED lineup is primarily aimed at farms with large sunflower areas, agricultural holdings, service providers and contractors working on different fields with different sowing technologies. The row-independent concept reduces dependence on a specific row spacing, which is important where machinery works not within one uniform production system during the season, but across different conditions.

For the Ukrainian market, this topic is also relevant. Sunflower remains a strategic crop for many regions, and high-quality harvesting directly affects the economics of the season. Header losses, additional load on the combine, downtime caused by incorrect settings or worn working elements - all of this quickly turns into real money. Therefore, interest in headers with flexible adjustment and high output is growing naturally.

Spare Parts for CLAAS Headers and Other Brands

For stable header operation, not only the design itself matters, but also timely maintenance. Spare parts for Claas headers can be purchased on the BAS-AGRO LLC website in the section: https://bas.ua/shop/compatible-with-claas-000000064-1. Spare parts for sunflower, corn and other headers from different manufacturers are also available in a separate section of the BAS-AGRO online store: https://bas.ua/shop/spare-parts-for-reapers-000000016-1. This is convenient for farms that service different types of headers and want to quickly select the necessary parts before the season or during harvesting.

The expansion of the CLAAS SUNSPEED lineup up to 11.90 m shows the general direction of sunflower harvesting technology: higher output, greater adaptability and less dependence on a specific sowing pattern. The row-independent principle, adjustable spacing between feeding elements, reel control while driving, and integration with CEBIS and CMOTION make the new headers not only wider, but also more technologically flexible.

For farms, the key question is not only how many meters of working width a header has, but how precisely it works with the actual crop in the field. In this sense, the new SUNSPEED is interesting precisely as a system combining high productivity with field adaptation. And for sunflower, where every percent of losses has economic significance, such adaptation may be no less important than the power of the combine itself.
