Axial Flow 250 Series
Built for the challenges associated with high-yielding crops, climate change and the need to become ever more efficient, Case IH Axial-Flow® combines are changing the landscape of harvesting-technology yet again. With the latest features including AFS Harvest Command™ automated harvesting technology, the 250 Series meets the demands of large modern farms and contracting businesses: high-speed harvesting, increased threshing capability even under the most challenging conditions, and delivery of unbeatable grain quality. As inventor of the single Axial-Flow® rotor design on self-propelled combines, Case IH continuously innovates to maximise your productivity. Feeder, rotor, grain tank, unloading system and automatic adjustments are designed to handle large grain throughput and ease your harvest.
An option for combines fitted with high capacity grain tanks and unloading systems; this is a revolutionary, self-contained system which communicates with all key combine elements and optimises the combine settings according to one of four chosen strategies to deliver maximum capacity in any harvesting conditions.
In real time, settings such as rotor speed, rotor cage vane adjustment, speed of the cleaning fan and cleaning sieve openings are automatically and continuously altered to guarantee the highest productivity and grain quality - without driver intervention.
All types of operator will gain from the system, but those who are less experienced will particularly benefit, as the combine now takes the necessary decisions to optimise performance.
Best grain quality - even in adverse conditions
Especially developed for changing harvesting conditions, the Axial-Flow ST-rotor is the key to the highest grain quality. Designed with a rasp bar configuration allowing straw to pass yet catching all the threshed ears, it allows operators to achieve high throughput and quality threshing, particularly in high yielding and tough European straw conditions. The multipass effect, moving the crop repeatedly over the concaves, allows a gentle threshing effect to rub out stubborn grains, while the rotation creates high centrifugal forces, moving the grain without mechanical impact through the concaves. This Axial-Flow concept is the undisputed leader in gentle threshing and unbeatable undamaged grain sample content.
Residue management - the start of the next crop
Whether it precedes conventional, min-till or no-till establishment, finely lacerated, evenly-spread straw provides the best start for the next crop, boosting breakdown and enhancing incorporation speed through natural processes. Choose from the integral chopper version or the Xtra-Chopping system to suit your requirements. The integral chopper is used for chopping or for transferring residue for when leaving unchopped swaths. Four different modes of operation are available: typical chopping mode, spreading long straw, and swathing with or without chaff. Straw from the rotor and chaff from the cleaning system are mixed and spread evenly during the spreading process, regardless of which system is used. And whichever mode is selected, it is a quick and simple process to switch from swathing to chopping, carried out from the operator’s seat via the AFS 700 Pro monitor.
Unbeatable grain quality
Capable of harvesting many different crops via quick and easy adjustments, Axial-Flow combines are among the most advanced machines on the market. Thanks to the single rotor Axial-Flow design, Case IH combines consistently deliver best grain quality and minimal grain loss. With the AFS Harvest Command™ option, the new 250 Series feature the latest harvesting technology, with auto-adjust sieves and auto-adjust cleaning fan to obtain the cleanest undamaged grain sample with minimal losses. An optional rain quality camera is available to form the heart of the full AFS Harvest CommandTM system, assessing levels of non-grain material and broken grains, and working fully automatically and in real time to adjust settings in response.
Increased traction with low ground pressure
Modern tyre technology allows for a combination of high travel speeds on the road and low ground pressure to protect soils in the field. Axial-Flow® combines can be fitted with anything from VF710/70 R42 tyres for transport widths below 3.5m to IF900/60R32 for flotation on softer soils. With a front track option it's possible to boost traction and flotation for effective soil protection on sensitive soils, whilst ensuring a transport width of just 3.5m on 610mm tracks. The hydrostatic ground drive features a variable speed motor option which enhances traction and hill-climbing ability for consistent ground speed. The new two-speed transmission with hydraulic high/low switch provides ample traction to handle difficult conditions. Depending on your requirements with regard to drive comfort and ground pressure, you can choose between rubber-damped or suspended track options.
Precision equals performance
Case IH Advanced Farming Systems (AFS™) collect and deliver important data for your management decisions on crop cultivation and cost management. By means of AFS AccuGuide GPS-controlled auto-steering, your combine is guided automatically – with a repeatable accuracy down to 2.5cm, track after track, to reduce overlaps and minimise time and fuel consumption during harvest. Precision farming technology reduces operator fatigue, boosts productivity and lets you exploit the combine’s full capabilities. With AFS Connect™, all your data are transferred to your farm computer in real-time, enabling you to provide instant advice and directions whenever you see the need to make immediate operating adjustments.
