Case IH Maxxum 5120-5150

Introduced in the spring of 1990, the Case IH Maxxum was an exceptionally completely new tractor. Even the engines were entirely new, resulting from a collaboration between Case IH and Cummins. The 4-cylinder had a displacement of 3.9 liters, which had also been used before in Cummins engines, and the six-cylinder had 5.9 liters. The engines were manufactured at Case IH's factory in Germany. The French-made transmission was advanced for Maxxum's size category: it featured a standard 4-speed powershift and a hydraulic reversing shuttle, which, unlike most other designs, was implemented with separate exhausts for forward and reverse driving. In terms of features, the Maxxum was the first tractor in its class to become the most modern, following the MF 3000 series introduced four years earlier.

The Maxxum was also modern in appearance and quite compact in external dimensions. The cab's noise level was not quite the best for its time. The six-cylinder models featured a digital instrument panel. The operation of the electronic hitch was implemented somewhat unusually and less intuitively compared to the normal approach.

At the beginning of 1993, the most powerful model in the lineup was introduced as the 125-horsepower 5150, distinguished by cooling vents on the side panels. The transmission and power take-off were more robust than those of the smaller models. At the same time, the 5130's engine was tuned to be more torque-rich by changing the injection pump, and a stripped-down S model was introduced alongside it, equipped with a synchromesh transmission without a quick shift. However, the S model still had a hydraulic shuttle and came standard with a push-button clutch. The 5140 got 520 mm rim tires as standard equipment. The rear mudguards were wider throughout the entire lineup, and the door glasses covered the full height of the door. The seat changed from Sears to Grammer.

In spring 1994, the Maxxum Plus models were introduced, which included several small updates, such as a neutral position for the reversing shuttle, a softer-functioning clutch pedal, synchronization of creep gears, and the routing of cables through the rear window corner.
