Transmission Options and Gear Ratios for Field Work

The 2007 John Deere 4120 offers multiple transmission configurations that suit various field operations. Here’s a breakdown of the key options and gear ratios for optimal performance.

The 4120 features a 12-speed SyncShuttle transmission, providing smooth shifting between gears for tasks requiring consistent speed control. With gear ratios designed for both field and transport work, it allows for precise adjustments depending on terrain and load conditions.

For field work, the low range gear ratios provide a balance between power and speed, ideal for tilling, planting, or heavy-duty harvesting. In particular, the following gear ratio range can be applied:

• 1st Gear: 5.07:1 – Ideal for slow, controlled movements during intensive tasks like plowing or deep tilling.
• 2nd Gear: 3.73:1 – Works well for moderate field tasks, offering a balance between torque and speed.
• 3rd Gear: 2.77:1 – Suited for tasks where more ground speed is required without sacrificing too much torque.
• 4th Gear: 2.03:1 – Effective for lighter field operations and transporting equipment over short distances.

For transport applications, the higher gears come into play, offering quicker speeds for road travel or moving across open fields.

The transmission design also includes a synchronized shuttle, allowing for smooth direction changes without needing to stop or disengage the clutch, beneficial for tasks like front loader work or reversing in tight spaces.

In addition, the PowerShift option provides the flexibility of automatic shifting between certain gears, which can be particularly useful for tasks that require constant speed adjustments but don’t involve heavy load variations.

By carefully selecting the appropriate gear for the task, operators can maximize efficiency and minimize fuel consumption, ensuring the John Deere 4120 performs optimally for a wide range of field work scenarios.
