ENGINE DETAIL
The Steiger Panther IV KM-325 is powered by a robust Cummins NT-855-A325 engine, delivering 325hp and a substantial torque output of 1080 lb-ft at 1400 RPM, making it well-suited for heavy-duty agricultural tasks. With a large displacement of 14.0L and an operating RPM range of 1700-2100, it ensures sustained performance under load while also requiring considerable oil (42 qts) and coolant (66 qts) capacities for effective engine management. However, the high torque characteristics may pose challenges for fuel efficiency if not managed properly in varying load conditions.

STEIGER PANTHER IV KM-325 TIRES
The Steiger Panther IV KM-325 features a robust AG front tire size of 20.8x34, optimizing traction and stability in diverse soil conditions. The rear tire options, ranging from 20.8x34 to 30.5x32, offer flexibility for load-bearing capacity and terrain adaptability, enhancing performance in heavy-duty applications such as tillage and hauling. However, the choice of larger rear tires may lead to increased soil compaction; therefore, careful selection based on specific operational scenarios is crucial for maximizing efficiency.

DIMENSIONS & TIRES
The Steiger Panther IV KM-325 has a substantial wheelbase of 129 inches, enhancing stability during heavy-duty operations, particularly in challenging terrains. Weighing 26,653 lbs, this tractor can manage significant loads but may present challenges in mobility on softer ground due to its weight. The use of 23.1x34 tires provides excellent traction and flotation, making it well-suited for fieldwork but may limit versatility on narrower or more confined paths.
