TRANSMISSIONS OVERVIEW
The John Deere 6155R features an advanced transmission system with options for 16-speed, 20-speed, and 24-speed configurations, providing flexibility in operation and efficiency for various farming tasks. The infinitely variable transmission (IVT) allows for seamless speed adjustments without having to shift gears, enhancing operator comfort and productivity, especially in tasks requiring fine control like tilling or planting. However, the complexity of the IVT may necessitate more in-depth maintenance and can be a challenge for operators unfamiliar with advanced transmission systems.

| Type | eight-speed power shift |
| Gears | 24 forward and reverse |
TRANSMISSION 4
The John Deere 6155R features an infinitely variable transmission (IVT) system, allowing for seamless speed adjustments without distinct gear shifts, enhancing operational efficiency and comfort during variable field tasks. This transmission type facilitates optimal power delivery and fuel efficiency, particularly beneficial in precision farming scenarios where consistent speed is essential. However, maintenance of IVT systems can be more complex and costly compared to traditional gear transmissions, so operators should be prepared for potential servicing challenges.
