TRANSMISSIONS OVERVIEW
The John Deere 940 tractor features an advanced 8-speed collar shift and an efficient 16-speed two-speed power shift transmission, providing operators with versatile gear selection for varying field conditions. The dual transmission system allows for smooth operation at different speeds and torque requirements, optimizing performance in both transport and fieldwork scenarios. However, the complexity of the power shift may require more maintenance and operator training, potentially leading to a steeper learning curve for less experienced users.

TRANSMISSION 1
The John Deere 940 features a collar shift transmission that allows for smooth gear transitions across its 8 forward and 4 reverse gears, optimizing operational efficiency during various tasks. The dry disc clutch provides reliable engagement and disengagement but may require more maintenance compared to oil-immersed models, particularly in heavy use scenarios. Pros include precise control in diverse field conditions, while its potential challenge lies in managing clutch wear over time in demanding applications.
