ENGINE DETAIL
The Century 3638 tractor features a 1.8L 4-cylinder diesel engine with a high compression ratio of 22.2:1, enhancing thermal efficiency and power output of 38 hp at 2600 RPM. Its dry element air cleaner aids in optimal air intake, while a coolant capacity of 9.8 quarts ensures effective temperature management, critical for prolonged operation. However, the relatively lower power output may present challenges in heavy-duty applications, making it more suitable for medium-scale farming and tasks requiring moderate towing or lifting capacity.

ENGINE OIL
The Century 3638 tractor has an oil capacity of 6.4 quarts (6.1 liters), which specifies the volume required for optimal engine lubrication and performance. It's crucial to maintain this oil level to prevent engine wear and ensure proper operation, especially under heavy load conditions. Regular oil checks and changes are recommended to maximize engine life and efficiency.

CENTURY 3638 ENGINE
The Century 3638 tractor features a Kukje 1.8L 4-cylinder diesel engine, providing a reliable and fuel-efficient power source for various agricultural tasks. Its compact size may offer maneuverability in tight spaces, although it might limit pulling capacity compared to larger models. Consideration of the specific torque curve is essential for optimizing performance in demanding applications like plowing or tilling.

TRANSMISSION
The Century 3638 tractor features a partially synchronized transmission with 12 forward and reverse gears, enhancing operator control during various agricultural tasks. It operates efficiently within a specific temperature range for hydraulic oils, requiring JDM J20C at low temperatures and JDM J20D for moderate conditions, which impacts performance in different climates. Note that the gear shifting requires the tractor to be stationary for range and shuttle changes, potentially slowing operational efficiency in dynamic field scenarios.
| Type | partially synchronized |
| Gears | 12 forward and reverse |
| Oil capacity | 37 qts/35.0 L |
| 10oF [-12oC] | : JDM J20C |
| 70o?-40oF [21o?-40oC] | : JDM J20D |
| Description | Four gears in three ranges with left-hand shuttle. Gear shift is synchronized with clutch. Tractor must be stopped to shift range and shuttle. |

MECHANICAL
The Century 3638 tractor features a 4x4 MFWD configuration, offering improved traction on varied terrain, making it advantageous for both agricultural and industrial applications. The hydrostatic power steering ensures ease of maneuverability, while the differential wet disc brakes provide reliable stopping power even in challenging conditions. However, the 12-speed partially synchronized transmission may limit operational efficiency in quick gear changes compared to fully synchronized options, potentially impacting productivity during tasks requiring frequent speed adjustments.

CENTURY 3638 TIRES
The Century 3638 tractor offers versatile tire configurations, enabling optimized performance across agricultural, lawn/turf, and industrial applications. For agriculture, the Ag front and rear tire sizes enhance traction on varied terrain, while the larger lawn/turf tire setup ensures reduced soil compaction and improved maneuverability in landscaping tasks. Industrial tires provide robust stability under heavier loads, making the tractor suitable for diverse operational scenarios; however, careful selection is essential to prevent performance compromise in specific applications.

DIMENSIONS & TIRES
The Century 3638 tractor has a compact wheelbase of 69 inches, enhancing maneuverability in tight spaces, which is ideal for small farms or landscaping tasks. Weighing 3,770 lbs, its stability is suitable for various terrain types; however, this weight may limit mobility on very soft soils. The tire specifications (8-18 front and 12.4-28 rear) provide good traction and flotation, making it effective for moderate field work but may need larger tires for heavy-duty applications.
