JOHN DEERE 4250 ENGINE

The John Deere 4250 features a robust 7.6L 6-cylinder diesel engine, providing high torque output suited for heavy-duty applications and efficient fuel consumption. Its PowerShift transmission offers seamless gear changes and enhances productivity in varied terrain conditions. However, challenges may arise in maintenance due to the engine's complexity and potential parts availability for older models.

TRANSMISSIONS OVERVIEW

The John Deere 4250 features a 16-speed partial power shift and a 15-speed full power shift transmission, which enhances operational versatility and efficiency, allowing for smoother transitions in speed during varying field conditions. The partial power shift offers greater control and less fatigue during long hours of operation, though it may require more operator skill for optimal performance. In contrast, the full power shift simplifies gear changes, making it advantageous for tasks requiring frequent speed adjustments, but it could potentially involve higher maintenance costs due to increased complexity.

TRANSMISSION 1

The John Deere 4250 features a John Deere Quad-Range transmission, allowing smooth partial power shifting between gears, with 16 forward and 6 reverse options, enhancing versatility in various field conditions. Its Perma-Clutch wet disc system ensures durability but requires the tractor to be stopped for range selection, which may affect operational efficiency in fast-paced tasks. This model is advantageous for tasks requiring precise speed control but may challenge users accustomed to completely clutchless shifting systems in more modern tractors.

TRANSMISSION 2

The John Deere 4250 tractor features a John Deere Power Shift transmission, allowing for clutchless shifting across 15 forward and 4 reverse gears, enhancing operational efficiency and reducing operator fatigue. The Perma-Clutch wet disc system provides consistent power delivery, but it's essential to monitor the oil capacity (42qts for 2WD, 54qts for 4WD) to ensure optimal transmission performance. This setup is particularly advantageous for tasks requiring frequent directional changes, such as plowing or hauling, although it may complicate repairs if transmission issues arise due to the complexity of the system.

JOHN DEERE 4250 TRANSMISSIONS

The John Deere 4250 features a 16-speed partial power shift transmission, which provides smoother gear shifting and improved efficiency, enhancing productivity during variable field conditions. Its 15-speed full power shift option allows for seamless shifting under load, reducing operator fatigue and increasing tractor performance. However, maintenance complexity may increase with the addition of power shift systems, necessitating a knowledgeable technician for repairs.

JOHN DEERE 4250 TIRES

The John Deere 4250 tractor's tire specifications indicate flexibility in both 2WD and 4WD configurations, accommodating various agricultural needs. The 2WD setup with 10.00-16 front and 18.4-38 rear tires provides a balance of traction and maneuverability, while the 4WD option with 14.9-26 front and the same 18.4-38 rear enhances stability and ground contact, ideal for challenging terrains. Users should consider that wider tires (such as 20.8-38) may improve flotation and reduce soil compaction but could impact fuel efficiency due to increased rolling resistance.

2WD Standard tires (ag) Front: 10.00-16. Rear: 18.4-38
4WD Standard tires (ag) Front: 14.9-26. Rear: 18.4-38
Ag rear 18.4-34 / 20.8-34 / 15.5-38 / 20.8-38 / 20.8R38

DIMENSIONS & TIRES

The John Deere 4250 tractor, with a 2WD wheelbase of 106.7 inches and a 4WD wheelbase of 105.3 inches, offers a stable operation suited for various agricultural tasks. Weighing between 11,755 and 13,855 pounds, it provides substantial traction, but the lighter configuration may challenge stability on uneven terrain while the 2WD setup limits performance in muddy conditions. The front tire size of 10.00-16 and rear tire size of 18.4-38 facilitate efficient power transfer, making it ideal for pulling heavy loads and cultivating larger fields.
