TRANSMISSIONS OVERVIEW
The John Deere 4760 features a 16-speed partial power shift and a 15-speed full power shift transmission, providing seamless gear transitions for enhanced operational efficiency. The partial power shift allows for more controlled speed variations, which is advantageous in tasks requiring precision, such as tillage or planting. However, operators may face a learning curve with the transmission's complexity, impacting initial productivity until they become accustomed to the shifting strategies.

TRANSMISSION 1
The John Deere 4760 features a Quad Range transmission with 16 forward and 6 reverse gears, providing versatility for various agricultural applications. The Perma-Clutch hydraulic wet disc design enhances durability and reduces slippage under load. This setup is particularly advantageous in operations requiring frequent gear changes and controlled power delivery, though it may present a learning curve for operators unfamiliar with partial power shift systems.

| Gears | 16 forward and 6 reverse |
| Clutch | Perma-Clutch hydraulic wet disc |
| Description | Four gears (1-4) in four ranges (A-D) with high-low power shift |
TRANSMISSION 2
The John Deere 4760 features a full Power Shift transmission, offering 15 forward and 4 reverse gears, which enhances operational efficiency in various field conditions. This transmission type allows for smooth gear transitions without clutching, minimizing operator fatigue during long hours of operation. However, potential challenges may arise in terms of maintenance cost and complexity, so regular servicing of hydraulic and electronic components is crucial for longevity.

MECHANICAL
The John Deere 4760 tractor features a robust 4WD system with inboard planetary final drives, providing excellent traction and stability in diverse terrains, although the 2WD option may limit performance in challenging conditions. Its 16-speed and 15-speed power shift transmissions enable efficient power delivery and smooth operation, enhancing productivity, but could present a learning curve for operators unfamiliar with partial versus full power shift systems. The Sound-Gard cab standard offers superior operator comfort and noise reduction, a significant advantage for long hours of use, although it may add to the tractor's overall weight and complexity.
