TRANSMISSIONS OVERVIEW
The John Deere 5125ML tractor features a 16-speed or 32-speed four-speed power shift transmission, offering enhanced versatility in various operational scenarios. The 32-speed option provides finer control over speed and torque, beneficial for tasks requiring precise maneuverability, like planting or tilling. However, the complexity of the 32-speed transmission may lead to increased maintenance requirements and learning curve for operators.
