ENGINE OIL
The Century 3647 tractor has an oil capacity of 7 quarts (6.6 liters), which is essential for maintaining optimal engine performance and longevity. Ensure regular oil changes to prevent engine wear and maintain efficiency, especially under heavy load applications. A larger oil capacity can enhance the cooling capacity and extend service intervals, but monitoring oil levels is critical to avoid damage from low oil situations.
CENTURY 3647 ENGINE
The Century 3647 is powered by a Kukje 2.3L 4-cylinder diesel engine, providing a compact yet robust powertrain suitable for various agricultural tasks. Key advantages include fuel efficiency and lower emissions typical of modern diesel engines, while the engine's size may challenge heavy-duty applications requiring more torque. Ideal for small to mid-sized farms, this tractor excels in tasks such as tilling and mowing, though users should assess its limitations for extensive heavy lifting.

TRANSMISSION
The Century 3647 tractor features a partially synchronized gear system with 12 forward and reverse gears, allowing for flexibility in various operating conditions. Its oil capacity of 37 quarts (35.0L) signifies a sturdy lubrication system, crucial for optimal performance, especially in extreme temperatures ranging from 10°F to 70°F (-12°C to -40°C) with suitable oil choices (JDM J20C or J20D). While the synchronized gear shift enhances ease of operation, requiring the tractor to be stopped for range and shuttle shifts may limit responsiveness during fieldwork, necessitating careful planning for implementation in time-sensitive tasks.

CENTURY 3647 TIRES
The Century 3647 tractor offers versatile tire configurations for agricultural, lawn/turf, and industrial applications, enabling optimal performance across diverse tasks. The combination of standard Ag tires (8-18 front, 12.4-28 rear) provides excellent traction for field work, while the larger lawn/turf options (29x12.00-15 front, 44x18.00-20 rear) enhance maneuverability and minimize soil compaction on lawns and parks. However, the availability of industrial tires (12-16.5 front, 17.5L-24 rear) may limit its adaptability for heavier construction tasks, posing challenges in scenarios requiring robust durability and load-bearing capacity.
