The four models of Challenger MT900C tractors range from 440 engine hp to 525 engine hp. The MT945C and MT955C are powered by Caterpillar C15 ACERT engines, and the MT965C and MT975C are powered by 18.1-liter Caterpillar C18 ACERT engines. The Advanced Diesel Engine Management system is the electronic control system paired with the engine to match performance with fuel economy. The MT900C Series is geared with a 16F/4R powershift transmission. Standard hydraulic flow runs 43.5 gpm, and an optional 59 gpm pump is available. Load Independent Flow Division (LIFD) ensures proportional oil flow to all circuits when the system is at capacity.

The Claas Xerion is available with three configurations: Trac (fixed cab in central position), Trac VC (cab rotates 180°) and Saddle Trac (cab fixed in position over the engine). Outfitted with 8.8-liter Caterpillar engines, the Xerion 3300 and 3800 Series provide 357 engine hp and 383 engine hp. Xerion tractors feature all-wheel drive, are outfitted with an infinitely variable ZF Eccom 3.5 transmission and have a maximum speed of 31 mph. Maximum standard hydraulic flow is 50 gpm, and an optional increased hydraulics package raises flow to 62 gpm. Up to nine remote-control valves can be connected at the front and rear. Another option is a rear PTO that swivels up to 15° on both sides.

The John Deere 9030 Series includes five-wheel models with a power range of 325 engine hp to 530 engine hp and three track models with a power range of 425 engine hp to 530 engine hp. All of the models are outfitted with 13.5-liter PowrTech Plus engines except for the 9230 model, which has a 9.0-liter PowrTech Plus engine. On track models, the AirCushion suspension system keeps the vehicle frame isolated from the track for a comfortable ride. Transmissions are as follows: standard 24-speed PowrSync transmission and optional 18F/6R powershift transmission on the 9230, 9330 and 9430 models, and standard 18F/6R powershift on the 9530, 9630, 9430T, 9530T and 9630T models. Hydraulics run at 48 gpm with an option of 78 gpm. The optional high-flow hydraulics are not available on track models.

The New Holland T9000 Series includes five models that range from 335 engine hp to 535 engine hp. The T9020 models are powered by New Holland 9-liter engines; the T9030, T9040 and T9050 models are powered by New Holland 12.9-liter engines; and the T9060 models are powered by Cummins QSX15 15-liter engines.

Standard and optional high-flow hydraulics run at 40 gpm/55 gpm on all models except the T9060, which runs at 42 gpm/57 gpm, respectively. The optional MegaFlow system includes a second hydraulic pump, and the system provides a total hydraulic flow of 90 gpm and 94 gpm on the T9060.

Buhler Industries showcased a new line of Versatile four-wheel-drive tractors. Available in 305 hp, 340 hp, 375 hp and 400 hp models, the four-wheel drives are powered by Cummins QSM11 engines with a 7% power bulge and 35% torque rise. Transmission options include a standard mechanical 12x4 transmission with four synchronized sequential gears in each of its three ranges or an optional 12x2 powershift transmission. The hydraulic system features load-sensing tandem piston pumps with a total capacity of 50 gal. per minute (gpm) or an optional high-flow package with 75 gpm. The grille area is 17% larger for better airflow and cooling for the big workhorses. The inside of the tractor cab is 8" wider, and a deluxe operator cab is available.

The Claas Xerion 3800 has numerous features but the most attention-grabbing is its ability to rotate the cab 180° in less than 30 seconds. At 382 hp, the Xerion 3800 is a higher horsepower version of the Xerion 3300, the company’s first tractor in the series. That tractor introduced a new concept—a variable cab position by relocating the cab to another position on the tractor body. The series is available with three cab position options: Trac, fixed in central position; Trac VC, cab rotates 180°; and Saddle Trac, fixed over position of the engine. Powered by a Caterpillar six-cylinder engine, this tractor can be used for tillage, planting, mowing, spraying, high-capacity manure work, silage pit work and grain or silage hauling. The Xerion 3800 features a continuously variable ZF transmission, permanent four-wheel drive, 100% front and rear differential lock and a 100% central differential lock.
