ENGINE DETAIL
The Steiger Panther III ST-325 is powered by a robust Caterpillar 3406DIT engine, delivering 325hp at 2100 RPM and an impressive torque of 1015 lb-ft at 1200 RPM, making it suitable for heavy-duty applications like tillage and large-scale farming. Its high displacement of 14.6L and a compression ratio of 14.5:1 enable efficient fuel combustion, though maintaining optimal cooling with a 70-quart capacity is essential to prevent overheating under high loads. While the oil capacity of 36 quarts supports prolonged operation, regular maintenance is crucial to ensure engine longevity and performance reliability in demanding conditions.

TRANSMISSIONS OVERVIEW
The Steiger Panther III ST-325 tractor features a 10-speed transmission option, providing precise control and efficiency across different terrains, while the 20-speed transmission enhances torque management and operational versatility. The dual transmission choices allow for optimized fuel efficiency during varying field tasks, yet the increased complexity with the 20-speed may present challenges in maintenance and operator training. Ideal for large-scale farming operations, this tractor excels in heavy tillage and long-haul applications, providing robust performance under demanding conditions.

TRANSMISSION 1
The Steiger Panther III ST-325 features a 10 forward and 2 reverse gear transmission, enabling versatile speed control for various field conditions and applications. Its hydraulic dry disc clutch offers efficient power transmission with minimal maintenance, although it may have a lower torque capacity compared to wet clutches, which can affect heavy-load performance. This tractor excels in demanding tasks like tillage or planting, but operators should consider the gear configuration's impact on maneuverability in tight spaces.

TRANSMISSION 2
The Steiger Panther III ST-325 features a Dana-Spicer 1010-3B transmission, optimizing power delivery with 20 forward and 4 reverse gears for enhanced maneuverability in varied terrain. The inclusion of a ten-speed transmission with a two-speed transfer case allows for flexibility in speed and torque, making it suitable for both heavy-duty fieldwork and transport operations. A large 393.7mm dry disc clutch ensures efficient power transfer but may require more maintenance compared to hydraulic options, especially in challenging conditions.

MECHANICAL
The Steiger Panther III ST-325's 4x4 articulated 4WD chassis provides exceptional maneuverability and traction over varied terrain, making it suitable for demanding agricultural applications. The outboard planetary final drives enhance durability and power transfer, though they may require more maintenance compared to standard drives. With hydrostatic power steering and hydraulic disc brakes, operators benefit from enhanced control and safety, while the choice of 10-speed or 20-speed transmission allows for adaptability in field operations, although the complexity could be a learning curve for less experienced operators.
