TRANSMISSIONS OVERVIEW
The John Deere 4520 features a 12-speed hydrostatic transmission, offering smooth and precise speeds for varied terrain and tasks, enhancing operator control and reducing fatigue. The hydrostatic design allows for seamless adjustments in speed without the need for manual clutching, which is advantageous in applications requiring constant speed changes, such as tilling or mowing. However, the complexity of hydrostatic systems may lead to higher maintenance costs compared to conventional gear transmissions.
| Description | 12-speed hydrostatic |
TRANSMISSION 1
The John Deere 4520 features a PowrReverser transmission, providing 12 forward and reverse speeds across three ranges and four gears, which enhances workflow efficiency during varied tasks. Its oil capacity of 41.2 quarts (39.0L) necessitates using appropriate fluids: Deere HY-GARD for cold conditions and Low-visc HY-GARD or JDM J20C/D for warmer climates, impacting performance and longevity. Key advantages include seamless gear shifting while in motion; however, the requirement to stop and depress the clutch to change ranges may limit operational speed in certain scenarios.

| Gears | 12 forward and reverse |
| Oil capacity | 41.2qts / 39.0L |
| 0oF [-17oC] | Deere HY-GARD |
| 100oF [37oC] | Low-visc HY-GARD / JDM J20C / J20D |
| Description | Power Reverser uses three ranges, four gears, and a reverser to provide 12 speeds in each direction. The tractor must be stopped, and clutch depressed, to change ranges. The gear can be changed while the tractor is in motion using the clutch. The clutch is not needed to change directions with the reverser lever |
