VALTRA 6550HI POWER
ENGINE DETAIL
The Valtra 6550Hi features a robust SisuDiesel 44 ET turbocharged engine, providing 103.3 hp at 2200 RPM and impressive torque of 324.5 lb-ft at 1400 RPM, optimizing performance for heavy-duty tasks. With a displacement of 4.4L and a bore/stroke ratio well-balanced for torque delivery, this tractor is suited for demanding agricultural applications, especially in mid-sized farms. However, operators should note the relatively lower rated RPM, which may limit its top-end speed in specific high-speed towing scenarios but enhances torque availability at lower speeds for better pulling power.

TRANSMISSION
The Valtra 6550Hi's three-speed power shift transmission provides efficient gear management with a total of 36 forward and reverse gears, allowing for versatile operation in diverse field conditions. The wet disc clutch enhances durability and smoother engagement, making it advantageous for tasks requiring frequent shifts, such as plowing or hauling heavy loads. However, the complexity of the transmission may present a learning curve for operators unfamiliar with power shuttle systems, potentially impacting productivity during initial usage.

VALTRA 6550HI TIRES
The Valtra 6550Hi, equipped with standard agricultural tires (14.9R24 front and 18.4R34 rear), offers optimal traction and stability for diverse field operations. The larger rear tires enhance grip and floatation, making it suitable for work on softer soils or during wet conditions. However, the tire selection may limit its agility in tight spaces, necessitating careful maneuvering in smaller fields or applications.
