TRANSMISSION 2
The John Deere 7220 equipped with AutoQuad transmission features 24 forward and reverse gears, providing versatile speed options and enhanced control over various agricultural tasks. This system optimizes power delivery and improves efficiency during operations such as tillage or planting, allowing for precise speed adjustments. However, the complexity of the transmission may require more maintenance and operator training to fully leverage its capabilities.
| Transmission | AutoQuad |
| Gears | 24 forward and reverse |
TRANSMISSION 3
The John Deere 7220 tractor features an Infinitely Variable Transmission (IVT) allowing for seamless adjustments in speed without discrete gear shifting, enhancing operator comfort and efficiency. Its design supports infinite forward and reverse movement, making it ideal for tasks requiring fine speed control in confined spaces or variable terrain. However, note that IVT is available exclusively with Mechanical Front-Wheel Drive (MFWD), which may limit applications for users needing traditional two-wheel drive.
