ENGINE SPECIFICATIONS
The John Deere 9R 640 is powered by a Cummins X15 engine featuring a 14.9L displacement, providing high torque at 2100 rpm, ideal for heavy-duty applications. Its advanced aspiration system with a variable geometry turbocharger and cooled EGR enhances fuel efficiency and reduces emissions, conforming to the stringent Final Tier 4 standards through a comprehensive aftertreatment package. Notably, compatibility with B20 diesel offers flexibility in fuel choice, although this can sometimes lead to increased maintenance needs associated with higher biodiesel content.

ENGINE PERFORMANCE
The John Deere 9R 640 tractor delivers a robust rated power of 640 hp with a power boost capability of 8%, enhancing performance under demanding conditions. Its engine peak torque of 2890 Nm at 1600 rpm ensures exceptional pulling strength, making it adept for high-load applications such as plowing and heavy tillage. However, the PTO power of 335 hp may limit its effectiveness in PTO-driven tasks if high torque is required at lower engine speeds, necessitating careful selection based on operational needs.
| Rated power | 471 kW/640 hp |
| Rated PTO power (hp SAE) | 249 kW/335 hp |
| Power boost | 8 percent |
| Maximum engine power | 508 kW/691 hp |
| Engine peak torque | At 1600 rpm: 2890 Nm 2132 lb-ft |
| PTO torque rise | 35 percent |
TRANSMISSION
The John Deere 9R 640 features the e18 18-speed PowerShift transmission, providing precise gear selection for optimal fuel efficiency and performance at high speeds of up to 40 km/h (25 mph). This system enhances operational efficiency, particularly in large-scale farming applications, allowing for seamless gear transitions under varying load conditions. However, the complexity of the transmission may present a learning curve for operators unfamiliar with advanced technology, necessitating proper training to maximize its benefits.

TIRES
The John Deere 9R 640 tractor has a consistent turning radius of 6.035 m (19.8 ft) regardless of brake engagement, which highlights its maneuverability, particularly beneficial in tight spaces or when performing headland turns. However, the turning radius may limit agility in confined environments compared to smaller tractors. Understanding this characteristic is crucial for optimizing field layout and reducing soil compaction during turns.
