TRANSMISSIONS OVERVIEW
The John Deere 8335R features a 16-speed full power shift infinitely variable transmission (IVT), enabling seamless gear transitions and optimized power transfer under varying load conditions. This design improves fuel efficiency and enhances operator comfort, particularly in applications requiring frequent speed adjustments. However, the complexity of IVT can introduce higher maintenance costs and requires advanced training for operators to maximize its potential in high-torque scenarios.
| Description | 16-speed full power shift infinitely variable transmission (IVT) |
TRANSMISSION 1
The John Deere 8335R's Automatic PowerShift transmission enhances operational efficiency by utilizing computer control for seamless load-responsive gear shifting, offering 16 forward and 4 reverse gears. The full power shift design allows for smooth transitions, minimizing operator fatigue during extended use. An optional fifth reverse, available through dealer reprogramming, provides added versatility for maneuvering in confined spaces, especially beneficial in tasks requiring frequent direction changes.
