New CaseIH MXM Maxxum mid-range row-crop tractorsCaseIH - July 12, 2002
Completely redesigned for 2002, the Case IH MXM Series Maxxum tractors provide more horsepower, more standard equipment, and more features to improve operator comfort and field efficiency.
"With horsepower ranging from 95 to 160 PTO hp, Case IH MXM Series tractors offer a variety of features to boost efficiency and productivity both in the field and feedlot," says Ray DeMond, product specialist for over 100 PTO hp tractors. "MXM tractors pair well with loaders, planters, balers, mower conditioners and tillage tools."
Four standard wheelbase models – the MXM120, MXM130, MXM140 and MXM155 – offer 95, 105, 115 and 125 PTO hp, respectively. Two additional long wheelbase models – the MXM175 and MXM190 – provide 145 and 160 PTO hp. All six are available in 2-wheel drive and mechanical front-wheel drive (MFD) configurations.
Power and performance Powered by a 7.5-liter turbocharged and aftercooled Case IH engine, MXM Series Maxxum tractors are rated at 2,200 rpm. However, they produce their maximum torque at 1,400 to 1,500 rpm with a torque rise of 30 to 40 percent, depending on model.
Long wheelbase MXM models offer an all-new, innovative engine management system. This new feature ensures that the operator will get the maximum horsepower in non-static PTO and roading applications. It also reduces the effects of parasitic loss in both of these applications, improving overall productivity.
Electronic engine management will ensure that the PTO maintains its rated speed when the additional power is needed. Also, when transporting in 16th gear or higher, maximum engine horsepower is automatically made available when conditions warrant.
"The MXM operator can rest assured that the system’s additional 35 horsepower will be used to the maximum benefit without having to lift a finger," DeMond explains. "No programming or attention is needed."
More comfort, more productivity A redesigned cab offers operators more glass area and a sloped front hood design for better visibility. In addition, it provides improved access and comfort with two standard doors, additional storage space and an adjustable cab suspension system that reduces shock loads to the operator by 25 percent.
Case IH customers will feel at ease with ergonomically designed throttle and shift levers in the style of Case IH MX Series Magnum™ tractors. A fully adjustable air suspension seat offers pneumatic lumbar support and an optional heated seat cushion. For an even better ride and longer axle life in tough conditions, Case IH offers an optional MFD front axle suspension system.
"The Case IH suspended axle offers 4.2 inches of vertical movement and a fully locking front differential for increased traction, better steering control and maximum stability," DeMond explains. "We offer a simple but effective and affordable system that also can be locked out with a switch in the cab."
Automatic features boost efficiency To improve field productivity and reduce operator stress, Case IH MXM Maxxum tractors possess standard end-of-row functions in all models. When the tractor is in auto mode, the differential lock and MFD will temporarily disengage when typical transport or turning conditions are met. For example, if speeds exceed 12 mph or the steering angle exceeds 30 degrees while ground speed is below 6 mph, the MFD will disengage.
The headland management control system – available on long wheelbase MXM models – takes that concept to the next level. It allows the operator to record up to 28 tasks, either as a continuous program or a number of small programs.
"Customers can record all of the tasks they commonly perform in the headland, like raising and lowering implements, shifting gears and regulating engine speed," DeMond notes. "Once programmed, the tractor will perform these functions automatically with just the push of a button."
Efficient systems Hydraulic power is provided through a two-pump system. A 32-gpm (28 for standard wheelbase) pressure flow compensating pump strokes only to pump the amount of oil the system needs for maximum efficiency. A separate 14.5-gpm steering pump operates independently for up to 46 gpm of total flow.
"Producers told us they wanted more options in the area of hydraulics, so we increased the number of remotes and added a joystick and programmable electronic switches," DeMond explains. "MXM long wheelbase models come with a joystick and up to four mid-mount remotes for loader use, and up to five, fully programmable, electrohydraulic rear remotes." An optional joystick for the third and fourth rear remotes also is available.
Using the MXM mid-mount remotes and the loaders’ standard quick connect, new Case IH loaders mount in only 10 minutes. Two new Case IH loader models – the LX162 and LX172 – offer optional mechanical (standard on LX172) or hydraulic self-leveling functions and an EZ Change quick coupler. The LX162 provides a 3,900-pound lift capacity, while the LX172 offers an impressive 5,200-pound lift capacity.
"Case IH MXM tractors combined with LX162 and LX172 loaders create a high productivity system," DeMond says. "Programmable functions and high capacity buckets and attachments allow operators to handle big jobs quickly."
An 18X6 full powershift transmission is available on all models. The MXM120, MXM130, MXM140 and MXM155 also offer an 18X6 semi powershift transmission. Both provide for clutchless, left-hand shuttle control, programmable shuttle speed and an optional creeper. The full powershift also offers auto transport, auto speed matching and auto field mode functions. When placed in field mode, the transmission will automatically shift between gears one and 12.
