CHALLENGER MT875B TAKES TOP SPOT WITH CAT ENGINE
THE AGCO Challenger MT800 series tractors already rank among the top performers in the high-horsepower tractor category. Now a new B generation ups the ante, and an all-new model, the MT875B, debuts with a massive 570 gross engine horsepower.
“Each one of the MT800B series tractors features an additional 10 to 20 hp, compared to its predecessor,” says Tim Miller, general marketing manager for Challenger track tractors. “However, the new MT875B not only expands the lineup, but takes gross engine horsepower to a new level among modern-day production tractors.”
All MT800B models, including the 875B, will be available in both ag and special application versions to handle the needs of large-acreage farmers as well as industrial and scraper operators.
Much of the horsepower boost can be attributed to new Caterpillar ACERT engines, which achieve Tier III EPA emissions compliance without the need for energy-sapping after-treatment devices. The Challenger MT835B, MT845B and MT855B tractors each use the 928-cu.-in. (15.2-liter) Cat C15 ACERT engine to achieve 350, 400 and 460 hp, respectively.
The two largest models in the series boast a 1,105-cu.-in. (18.1-liter) Cat C18 ACERT diesel engine that cranks out 510 hp in the MT865B and 570 hp in the MT875B. At the moment, that's the largest engine and the highest horsepower level in any production tractor in North America — track or wheel.
In addition to turbocharging, air-to-air aftercooling and four-valve-per-cylinder technology, both engines also feature a new “electronics control system” that enables smooth power delivery by coordinating communication between all tractor electronic control modules. The upgraded electronics improve the engines' ability to maintain power and reduce noise, even with changing fuel temperatures.
Customers who operate on compacted and unbroken soils, like those encountered in a scraper application, may want to choose a new special application belt option. The new belts have 2.5-in. tread bars to reduce flex and improve wear. The belts are thicker, with two additional layers of rubber on the inner belt surface to reduce debris damage.
The new B models also include a number of cab improvements, including a noticeable sound level reduction, a FOPS (falling object protective structure) built into the cab roof, and a new semi-active operator's seat that allows for continuous real-time automatic damping force in any one of three positions, based on terrain inputs.
BOURGAULT ADDS SEEDER WITH LARGEST TANK CAPACITY
A NEW MODEL air seeder has been added to Bourgault Industries' 6000 series of seeders. The Leading 6450 Air Seeder features the largest air seeder tank in the world, according to Bourgault. The seeder holds a total of 450 bu. in four separate tanks. Tank 2 may be diverted into tank 1 or 3 and tank 3 may be diverted into tank 4 or 2 through patented interconnect ports. The hitch weight is 8,500 lbs. when fully loaded.
Auger options include a 10-in. auger with standard hopper and hydraulic cylinder to assist in swinging the main arm or a 10-in. auger with folding low-profile transfer hopper and hydraulic controls. The metering transmissions are ground driven. Cost for the base configuration of the seeder is about $66,000, depending on tires and load/unload auger selected.
MARTENS ADDS IMPLEMENT
A NEW FLEX harrow system is available from Martens Manufacturing. The new harrow will help establish a better stand and higher yield by preparing a top seedbed for conventional and no-till systems, according to the manufacturer. The system is available in lengths of up to 521/2 ft. with an all-hydraulic front fold.
Prices for the harrow range from $2,500 to $3,500. Contact Martens Mfg., Dept. FIN, 915 E. State Rd., Fairview, OK 73737, 800/272-5824, visit www.martensmfg.com or www.freeproductinfo.net/fin, or circle 191.
