The standard SmarTrac Lateral Tilt system helps you harvest more grain by adjusting header tilt up to four degrees in either direction to follow the contour of the ground. Electronic potentiometer sensors detect changes in the terrain and automatically activate movement of the header to compensate. SmarTrac Lateral Tilt can also be operated manually from the hydrostatic control handle in the cab, ensuring maximum harvesting efficiency when you need it most. Either way, you can monitor the tilt position on the C2000 terminal.
The feed conveyor on a Challenger combine is designed to keep crop material moving smoothly from the header to the rotor. It starts with a widefeed conveyor to maximize intake — 44 in. (1,121 mm) on the 660B and 55.4 in. (1,408 mm) on the 670B and 680B. The lower drum and chain are also designed to float up and down according to crop intake, to ensure constant chain-to-crop contact and positive feeding.
The AHS threshes the crop during multiple passes, gently allowing the grain to fall through the concaves. A multi-speed gearbox — three speeds on the 680B and two speeds on the 660B and 670B — allows the operator to select the ultimate torque and speed range, up to 1,040 rpm. The longest in the industry, the AHS rotor increases crop throughput, allowing the combine to maximize productivity and - in many cases - operate at higher ground speeds. The 660B and 670B rotor measures 27.5 in. (700 mm) across, while the 680B rotor spans a full 31.5 in. (800 mm) in diameter. The AHS performs four major functions via a single rotor, improving crop quality, reducing losses and lowering operating costs, all without the extra augers, drives, gears and discharge rotors found on other machines.
One look at the Challenger 600B Series cleaning system and you’ll understand why it’s called the “Wind Tunnel.” From the fan to the spreader, the Challenger cleaning system is designed to quickly and efficiently remove chaff, dirt and debris from high-yielding crops and move the grain quickly into the tank. Fan speed and air velocity are infinitely adjustable via two speed ranges and a variable speed control in the cab. Thanks to a large, 11-in. (279 mm) transverse cleaning fan on the 660B and 670B and a 13-in. (330 mm) transverse fan on the 680B, air starts separating the chaff from the grain the second it leaves the grates in the rotor.
A massive grain tank on all three models improves harvesting efficiencies by allowing longer intervals between unloading. It also allows for more time for the grain cart to unload, which means the combine will spend more time harvesting instead of waiting. The 660B and 670B feature a 300-bushel (10,570 L) grain tank as standard equipment with the option of a 350-bushel (12,330 L) tank on the 670B. The 680B comes standard with the 350-bushel grain tank.
In the meantime, unloading time is significantly reduced with the industry-leading 4.5 bushels/second unloading rate on all three MT600B Series models. Reduced daily unloading time by up to 45 minutes, compared to similar sized competitive models, and ultimately reduce fuel consumption, operator stress, and improve harvesting efficiencies.
Finally, the “direct flow” unloading auger uses only two augers instead of three for smooth, gentle grain flow. Because grain does not have to change directions during unloading, you’ll also experience higher grain quality, less wear and reduced horsepower consumption.

This optional system allows the operator to fold the bin extension and the bin fill auger electrically from the cab with the touch of a switch.
Challenger 600B Series combines feature two different engines, depending upon the model, to ensure the best application of power for the job at hand.
AGCO Power™ 84CTA engines combine a number of advanced technology features to deliver high performance torque and exceptional fuel economy from their 8.4-liter (513 cubic inch) displacement. Electronic Engine Management 3 (EEM3) continuously monitors engine performance and is capable of making up to 100 adjustments per second to precisely manage fuel delivery and timing.
The Cat C13 engine, combines the strength and durability of a single-piece, 12.5-liter (763 cubic inch) block with ACERT® technology, ADEM-4 electronics and common-rail fuel injection. Both engines meet current EPA Tier III compliance standards without sacrificing performance, durability or reliability. And both offer a power bulge of up to 8 percent, for an extra 34 horsepower when you need it most — like powering through those tough spots in the field or unloading on the go. Both engines also feature ISOBUS electronics for seamless communications with the C2000 Console, which provides the operator with current engine data, accumulated and warning alerts.
The 600B Series center-mounted cab provides a clear view of the header and incoming crop through 61.2 square feet (5.7 m2) of tinted glass. You’ll have plenty of room to move comfortably, as well, since the 600B Series boasts the widest cab on the market with 121.4 cubic feet (3.43 m3) of interior space.
The minute you sit down in the deluxe air-suspension seat, you’ll appreciate comfort that adjusts to your height and weight in any manner you desire.
You’ll also notice the ergonomic seat-mounted control console that moves and floats with the seat, so controls are always at hand. That includes the hydrostatic handle, which controls ground speed and direction and incorporates switches for header and reel movement, electric corn stripper plate adjustment, and the unloader auger. The new C2000 terminal moves with the console and seat, as well, ensuring that control features and performance data are always close at hand and easy to read.
Other comfort and convenience features you’ll find in the spacious Challenger cab include:
The C2000 terminal found in all 600B Series combines is much more than a monitor. Comprised of a 10.5-inch, touch-sensitive color screen, nine hard keys, and a rotary dial, the C2000 terminal is a fully integrated system that is designed right into the combine. The monitor can customized to display the information that is most important to the operator. With the press of a button, the operator can move to virtually any display without scrolling through multiple screens. From one convenient, compact screen, the C2000 terminal allows the operator to monitor all combine, engine and hydraulic functions, check and adjust combine settings, monitor grain loss and keep track of loads, trips and service.
Because it uses ISOBUS communications and meets ISO 11783 standards, the C2000 terminal can be moved from the combine to control Isobus implements such as a White Planter or Challenger baler.
The C2000 Console can also support up to two remote video cameras, which allows the operator to view the area behind the combine and/or around the unloading auger.
Moving from crop-to-crop and field-to-field is simple with C2000 Console, too. All settings, including header width and cutting height, can be saved by crop type or field conditions. Up to 20 different crop settings can be saved and recalled at the push of a button, which means you can have one setting from high-moisture corn, one for dry corn, another for wheat, soybeans, etc.
Centered on the versatile C2000 terminal, the Fieldstar II precision farming system begins with a standard-yield monitoring system that collects data to display and record crop yield and moisture. With the appropriate desktop software, Fieldstar II can generate maintenance records, crop records and even field maps that provide an accurate record of yield variability throughout the field.
Challenger offers satellite-assisted steering systems to increase the productivity of your combine by reducing unwanted overlaps or skips. Challenger combines are compatible with AGCO’s AUTOGUIDE as well as the Topcon System 150 and AES-25 assisted-steering systems. Either will provide sub-meter, decimeter, and sub-inch accuracy. Plus, the Topcon System 150 can be used with CORS correction signals, if available in your area. Whether you need 8-inch pass-to-pass or 0.8-inch, Challenger has you covered.
A less complicated machine means less maintenance, fewer repairs and an earlier start to your day during one of the busiest times of the year.
Other features that simplify maintenance, besides the simple drive, which is limited to as few as eleven belts and three drive chains, include:
