Implements are bigger than ever, and work days are longer than ever. “Producers told us they want a tractor with more power and productivity to handle larger loads at higher speeds, with better fuel efficiency — all without sacrificing comfort,” says John Bohnker, Case IH marketing manager for Magnum tractors. Case IH is answering these producer demands with the new generation of 2011 model Magnum tractors.
The new Case IH Magnum tractors have more power and productivity, along with an improved operator environment and outstanding fuel efficiency. To meet 2011 Tier 4A emissions standards, the new Magnums employ Case IH Selective Catalytic Reduction (SCR) technology for maximum performance with the lowest possible operating cost.
“We’re meeting the Tier 4A standards while actually improving fuel efficiency at the same time, thanks to engine innovations with Case IH SCR technology,” Bohnker says. The new Magnum 235 through 340 models rely on the proven 8.7-liter engine used in the Axial-Flow 7120 combine in recent years, now Tier 4A compliant, while the Magnum 180 through 225 continue with the proven 6.7-liter power plant, also now upgraded to Tier 4A.
These engines provide the same responsive power growth that Case IH Magnum customers are accustomed to for tough pulling conditions, enhanced with new engine Power Boost capabilities. “Power Boost gives you up to an extra 35 engine horsepower available for roading or mobile PTO and hydraulic demands,” Bohnker explains. “For
example, if you’re pulling an implement that uses a great deal of hydraulic or PTO power, it’ll help you get through those tough conditions. The same holds true for roading on steep hills.”
Every 2011 Magnum has increased horsepower to handle today’s larger row crop implements. The new line-up offers nine models:
• Magnum 180, with 230 maximum engine HP, 150 PTO HP.
• Magnum 190, with 247 maximum engine HP, 165 PTO HP.
• Magnum 210, with 256 maximum engine HP, 180 PTO HP.
• Magnum 225, with 265 maximum engine HP, 195 PTO HP.
• Magnum 235, with 269 maximum engine HP, 185 PTO HP.
• Magnum 260, with 293 maximum engine HP, 205 PTO HP.
• Magnum 290, with 323 maximum engine HP, 230 PTO HP.
• Magnum 315, with 352 maximum engine HP, 255 PTO HP.
• Magnum 340, with 383 maximum engine HP, 280 PTO HP.
Case IH engineers also improved the cab environment on the new Magnum tractors. “A new suspended cab option gives you a smoother ride in the field and on the road,” Bohnker adds. “The cab suspension compensates four ways – front-and-back and up-and-down — so you don’t get bounced around on uneven terrain.”
The Magnum Surveyor cab still offers the industry-leading space, all-around visibility and comfort that represent hallmarks of the Magnum operator environment. And it now boasts the latest generation of Case IH operator control technology with the new MultiControl Armrest console. Extensive producer input in the design of this armrest guided the control layout, which puts key tractor functions at the operator's fingertips.
The MultiControl Armrest console is now standard in all Case IH high-horsepower tractors. “From the Case IH Puma up through Steiger tractors, you’ll find the same armrest and same controls, with the same look, feel and operation. That means less training for hired hands, and instant familiarity when jumping from the cab of one tractor to another,” Bohnker says.
A new AFS Pro 700 color display is integrated into the MultiControl Armrest and moves with the tractor seat. The AFS Pro 700 allows the operator to seamlessly control AFS AccuGuide autoguidance functions, as well as general tractor functions and other key adjustments through AFS Field Performer. The Pro 700 can be customized to display the key tractor operating information most important to the individual producer.
While AFS AccuGuide makes steering simpler, Case IH also takes the guesswork out of selecting which gear and engine speed will achieve the best possible fuel economy while meeting power requirements. All Magnum tractors are equipped with DieselSaver Automatic Productivity Management (APM) which automatically selects the most efficient gear ratio and engine speed combination. While Diesel Saver APM is activated, the operator simply selects the desired ground speed for optimized performance.
"SCR technology represents the best approach for high-horsepower agricultural equipment in 2011, especially considering the importance of fuel efficiency and maximum uptime in the field for large producers,” Bohnker continues. “Our engines are tuned and calibrated to do what they’re designed to do, which is to make efficient power.”
The SCR system separates most of the emissions control away from the main engine function. Unlike Exhaust Gas Recirculation (EGR) systems being used by many other manufacturers to meet Tier 4A government standards, Case IH SCR technology doesn’t recirculate exhaust gas back into the engine. “So there’s no need for a larger cooling system — or a diesel particulate filter that utilizes a heat-producing and fuel-consuming 'regeneration' process typically needed to meet Tier 4A with EGR,” he notes.
In an SCR system, engine exhaust passes directly to the SCR muffler where it is injected with Diesel Exhaust Fluid (DEF), a non-toxic, colorless, odorless mixture of chemical urea and purified water. “The new engine greatly reduces particulate matter because it’s designed for efficiency,” Bohnker says. “And we reduce nitrogen oxide (NOx) downstream by injecting DEF in the exhaust stream.” DEF converts NOx into harmless water vapor and nitrogen vapor released through the exhaust pipe. This DEF aftertreatment is key to allowing the enhanced fuel efficiency provided by Case IH SCR technology in the new generation Tier 4A engines.
With nearly all of the 2010 pick-up trucks and many 2011 off-road equipment manufacturers utilizing DEF technology, the fluid is available at diesel fuel outlets and agricultural input suppliers, including Case IH dealers.
“Filling the DEF tank is easy, and it’s designed to last at least as long as two tanks of fuel. We estimate that for every gallon of DEF, the SCR technology allows about two gallons of fuel saved,” Bohnker says.
The Magnum tractor's polyurethane DEF tank is located directly in front of the fuel tank, and can be filled from ground level. DEF is available in bulk, as well as large totes, 55-gallon drums and 2.5-gallon jugs. One DEF mini-bulk tote holds 275 gallons, and each Magnum tractor with average usage will typically use one tote per year.
To go along with the latest engine enhancements, Case IH also redesigned the hood, front surround frame and cooling system in the larger Magnum models. “A new front surround frame cradles the iso-mounted engine and isolates the tractor and operator from noise and vibration,” Bohnker continues. “To handle the higher horsepower, a redesigned cooling package provides enhanced cooling capacity with better efficiency.”
There are typically four different cooling units on a tractor, one each for the radiator, hydraulics, air conditioner and turbocharger. “When you stack these, it takes a lot of horsepower to pull air through that package,” Bohnker explains. “So for the highest-horsepower Magnum tractors, we separated three of the four cooling units. This requires less horsepower for cooling and leaves more power available for the implement to get the actual work done.”
A redesigned rear 3-point hitch improves clearance for lifting the hitch through its entire range of motion. And a new front-hitch/front-PTO option is available for specialty front-mounted, PTO-driven implements, further expanding the Magnum tractor's versatility. The Magnum 235-340 models also offer six hydraulic remotes with newly designed hydraulic valves. The new valves provide electronic positioning sensing as well as lock checks in both raise and lower ports.
In addition, the new Magnum tractors continue to be built AFS AccuGuide™ autoguidance-ready standard. “We also offer the complete autoguidance package installed at the factory, so it’s ready to roll as quickly as possible after it arrives at the dealership.”
“Case IH customers are spending more time in the tractor than ever,” Bohnker adds. “So we designed our biggest Magnum tractors to handle the higher capacities of today’s agriculture, without sacrificing Magnum’s legendary operator comfort.”
