JOHN DEERE 4420 POWER
ENGINE DETAIL
The John Deere 4420 tractor is powered by a robust 6-cylinder diesel engine, offering 102 hp at a rated RPM of 2500, which is well-suited for agricultural tasks that require consistent power delivery. With a torque peak of 259 lb-ft at 1400 RPM, it provides strong low-end performance, making it ideal for heavy-duty applications such as plowing and towing. However, its oil and coolant capacities (13.75 qts and 20.6 qts, respectively) necessitate regular maintenance to ensure optimal performance and engine longevity.

JOHN DEERE 4420 ENGINE
The John Deere 4420 is powered by a robust 5.4L 6-cylinder diesel engine, providing reliable torque for various agricultural applications. With a 34.1-gallon fuel tank, it allows for extended operational time, reducing downtime for refueling—ideal for larger fields or extended tasks. However, the relatively smaller tank size compared to modern tractors may require more frequent refueling during extensive operations, posing a challenge for efficiency in large-scale farming settings.

TRANSMISSION
The John Deere 4420 features a Syncro-Range transmission offering 8 forward and 2 reverse gears, providing good versatility for various field operations. The synchronized gear shifting allows for easier operation, enhancing efficiency during tasks like plowing or tilling. However, operators should be mindful that the limited reverse gear options may be a constraint in tight spaces or on hilly terrain, where maneuverability is crucial.

MECHANICAL
The John Deere 4420 tractor features a robust 4x2 2WD chassis with planetary final drives, providing a balance of simplicity and durability for light to moderate fieldwork or road transport. The hydraulic wet disc brakes offer reliable stopping power, but the open operator station may expose the operator to elements, which could impact comfort during extended use. The 8-speed transmission allows for efficient speed control, making it versatile for various tasks, though limited traction in wet or uneven terrain could present challenges.

JOHN DEERE 4420 TIRES
The John Deere 4420 features agricultural front tires of size 7.50x18 and rear tires available in 18.4x34 or 23.1x26 configurations, providing versatility for various field applications. The larger rear tires enhance traction and stability, particularly in muddy conditions, while the front tire size maintains maneuverability. An important consideration is the balance between tire size and the tractor's overall weight distribution, which can affect performance during heavy loads or in hilly terrain.

DIMENSIONS & TIRES
The John Deere 4420's 100.4-inch wheelbase ensures stability, particularly in hilly terrains, while its substantial weight of 8283 lbs provides good traction for heavy-duty applications. The front tires (10.00x16) offer maneuverability, but you may experience limited flotation in soft soil conditions compared to the larger rear tires (23.1x30), which enhance driving capabilities during tilling or heavy towing. Overall, its robust design is advantageous for row crop farming yet may challenge transport on narrow roads due to its bulk.
