Axial-Flow 250 Series

45 Years of High-capacity, High-efficiency Harvesting

For over four decades, the Axial-Flow 250 series combine set the standard for high-capacity and highly efficient harvesting. Designed to optimize grain quality and grain savings, the 250 series combines with optional AFS Harvest Command™ automation simplifies harvesting by sensing and optimizing machine settings — regardless of operator skill level.

AFS Harvest Command automation is officially supported for the following crop types: corn, soybeans, canola, barley, wheat and rice.

Explore Features

  • Every Bushel Counts

    All year long, you’ve put in the hard work to create incredible acres of food grade crops, including corn, popcorn, lentils, wheat, and rice. Now it’s time to collect. Every detail of Axial- Flow 250 series combines is designed to get every bushel out of your food grade harvest.

  • Increase Functional Performance Through The Feeding System

    250 Series Combines have a redesigned feeder house for demanding crop conditions. A redesigned feeder top shaft drive coupler features a crown spline design for greatly improved durability. A simple, two-piece feeder floor design increases durability and improves crop feeding. Plus, up to 13,500 pounds in lift capacity handles even the largest chopping corn head on the market. The latest updates include:

    • New configurable raise and lower buttons for the reel and header
    • Improved automated header height control (AHHC) for more responsive corn head operation
  • Shift Into the Model for You

    The two-speed electric shift ground drive transmission increases tractive effort and reduces the need to stop and shift in field or on the road. Wider speed ranges provide more power for climbing hills  and in challenging ground conditions. An optional differential lock further improves traction and performance. These combines are equipped with closed-loop sensing which ensures constant speed control plus an economy mode for fuel savings.

    Our industry-exclusive CVT drive provides reduced complexity and maintenance, while the improved PTO gear case design ensures pumps and drives are operating efficiently throughout the entire rpm range.

    Our patented header to feeder ground speed automatically matches header speed to ground speed with in-cab electronic variable feeder speed control, optimizing grain savings in down-corn conditions. Header and feeder automatically adapt to combine speed and put more grain in your tank.

  • Control Your Harvest

    We pioneered single rotor development back in the 1960s. Since then, refinements, enhancements and improvements have led to the pinnacle in rotor performance — the AFX rotor. The AFX rotor can be set into many configurations, adapting to both crop and threshing conditions.
  • High-Capacity Cleaning Systems

    High-capacity combines need large high-capacity cleaning systems. Axial-Flow combines match cleaning system capacity to the size of the machine, providing superior productivity, grain sample quality and savings. The patented design of the Cross Flow™ cleaning system fan delivers consistently clean grain samples no matter the harvest condition. 

    • Self-leveling Cleaning System (SLS): The self-leveling sieves allow up to 12 percent slope each way. An in-cab, adjustable pre-sieve allows the operator to make adjustments on the go to maximize grain quality. 
    • Tri-Sweep™ Tailings Processor: Using three sets of impellers, the processor gently re-threshes and elevates the tailings, returning them back to the active grain pan for final cleaning. This results in higher capacity, increased efficiency and improved grain quality.
    • Active Grain Pan: Increases efficiency by separating the grain and other material through reciprocating action before reaching the cleaning system.
    • Cross Flow Fan: After entering the fan, a vortex is created, which super charges the air flow, giving a full-balanced flow across the entire sieve. Air enters the full width of the fan from the top — not the sides — resulting in superior air flow.
  • Maintain Easy, Effective Control

    The Case IH residue management system is built to handle the tough residue associated with new crop. This system delivers consistency across the larger header widths used on the Axial-Flow 250 series combines, helps prepare the ground for next year’s crop and can create consistent windrow formations and long straw for baling. 

    • Rotor Discharge Deflector: Positioned directly behind the rotor, providing a central feeding point and deflecting residue toward the chopper. The deflectors can be adjusted either from in-cab or the right-hand side of the combine by a pin that can be placed into four different positions.
    • Windrow Chute: Two residue modes (spread and windrow) provide options to meet your residue requirements, with an in-cab chop-to-swath option available.
    • Chopper: Blades are mounted in a spiral pattern, with seven separate chopper/residue options to match your requirements, including a factory-installed X-tra Chop; a small-grains residue package for increased residue chop and sizing.
    • Hydraulically Driven Spreader: Hydraulically driven residue spreaders are adjustable in-cab for on-the-go speed control. Spreading width is easily adjusted manually by moving the dovetail in the center up or down.
  • Reduce Your Unload Time

    Large grain tanks, longer augers and quick-folding tool-free grain tank extensions are standard on all Axial-Flow combine models — resulting in more efficient field operation. High unload rates, an optional cab-controlled pivoting spout, and optional cab-controlled grain tank covers add to the high productivity of the 250 series combines.

  • Find Your Perfect Flow With AFS Harvest Command™

    Regardless of the time of day, crop conditions or moisture levels, the AFS Harvest Command combine automation system is always working for you. It’s simple. Each automation mode prioritizes different harvesting outcomes — from grain quality to grain savings to throughput. Choose the mode of automation to match your harvesting goals. Then set the crop type, maximum operating speed and power limits and AFS Harvest Command takes over from there.
  • Eliminate Guesswork. Simplify Your Harvest.

    From the AFS Harvest Command™ combine automation system to the factory-installed AFS AccuGuide™ auto guidance system and more, you have the tools to optimize harvest — no matter the field conditions or operation skillset.

    With AFS Connect™, you have the power to monitor your operations from anywhere.

    • AFS AccuSync is available for machines operating with a Pro 700. AFS AccuSync provides machine coordination for up to six vehicles operating in the same field and allows you to easily create and share job information, like guidance lines, with the other machines.
    • Rice crops are now supported for AFS Harvest Command and retrofittable to Model Year 2019
    • New auto clean out feature allows you to easily clean your machine between crop types or varieties with an one button push on the Pro 700 display
