Why the redesigned Axial-Flow lineup is being called the best combine to hit the market — and why the competition should be worried.
When Case IH pulled the covers off its AF Series combines, the company didn’t just refresh a product line — it redrew the map for what a modern harvester can do. With the dual-rotor AF11 flagship and the completely re-engineered single-rotor AF9 and AF10, the AF Series stakes a serious claim as the most capable combine lineup ever put to work in a field.
Built From the Ground Up, Not Warmed Over
This is no cosmetic update. The AF9 and AF10 share fewer than 500 parts with the outgoing 260 Series — a near-total redesign of a platform that has defined rotary harvesting for nearly 50 years. The heart of the single-rotor machines is the new AFXL rotor: 40% longer than its predecessor, delivering roughly 50% more separation area. That means more grain in the tank and less out the back, even when conditions turn tough.
At the top of the range, the AF11 introduces the AFXL2 dual-rotor system, boosting threshing and separation area by 45% and giving Case IH its highest-capacity combine ever. With six threshing modules, twelve separating modules, and the exclusive HX+ rasp bars working inside a stepped rotor cage, the AF11 loosens the crop mat for cleaner separation at throughputs that would choke lesser machines. An industry-exclusive Power Plus CVT rotor drive — complete with rotor reversing — keeps the machine running when tough, damp crops would stop the competition dead.
Power and Capacity the Competition Can’t Match
The numbers tell the story. The AF10 and AF11 both pack a 775-horsepower FPT Cursor 16 engine, while the AF9 delivers 634 horsepower — putting the entire series at Class 9 or above and making it the most powerful combine lineup Case IH has ever offered.
Grain handling is equally dominant. A massive 567-bushel (20,000-litre) grain tank — among the largest in the industry — pairs with unload rates of up to 6 bushels per second. Fewer stops, faster unloads, more acres per day. Farmers running early AF11 units have reported that two machines can replace three of the previous-generation 9250s while delivering roughly 20% more capacity — a productivity leap that transforms the economics of a large operation.
The redesign extends to the cleaning system, too: a two-part cleaning shoe with dramatically more surface area that can shift sideways to keep sieves evenly loaded on slopes, plus a radar-guided chopper and spreader that lays residue evenly across the full cut width.
Smarter Than the Rest — With No Subscription Strings Attached
Where rivals increasingly nickel-and-dime farmers with software subscriptions, Case IH goes the other way. The AF Series ships with Harvest Command automation standard, using sensors throughout the machine to continuously adjust settings for maximum efficiency — no expert operator required. Dual Pro 1200 displays put customizable harvest data front and center, and the FieldOps platform delivers real-time machine and agronomic data to any mobile device with connectivity included for the lifetime of the modem — no subscription fees.
Add RowGuide Pro guidance, single-point yield calibration, and a cab featuring a heated, cooled, massaging leather seat, and the AF Series is as easy to run at hour fourteen as it is at hour one.
Why It Beats the Green Machines
Against John Deere’s X9 and Claas’s Lexion, the AF Series brings a fundamentally simpler, proven architecture: the legendary Axial-Flow single rotor, now longer and hungrier than ever, with fewer moving parts than conventional walker or hybrid designs — which historically translates to gentler grain handling, better grain quality, and lower maintenance costs. Against the New Holland CR11, the AF11 counters with Case IH’s red-blooded dealer network and the industry-exclusive rotor drive and automation package. And at spot work rates reported around 100 tonnes per hour in field demos, the AF10 is trading blows with — and often beating — anything else in the paddock.
The Bottom Line
More power. More capacity. More automation. Less grain loss, less fuel per tonne, and no subscription fees. The Case IH AF Series isn’t just an incremental step — it’s the machine the rest of the industry will spend the next decade chasing. For farmers looking to cover more acres in fewer hours with cleaner grain in the tank, the harvest just got a new benchmark. And it’s painted red.
