TRANSMISSIONS OVERVIEW
The John Deere 2640 features a versatile 8-speed collar shift transmission, which provides reliable performance for varied field applications, though it may require more operator skill than modern fully synchronized systems. The optional 16-speed two-speed powershift enhances productivity by allowing seamless gear transitions under load, ideal for demanding tasks. Meanwhile, the 8-speed power shuttle offers improved maneuverability in tight spaces, particularly beneficial for loader work but may necessitate careful coordination when switching between forward and reverse.

MECHANICAL
The John Deere 2640 features a 4x2 2WD chassis and a mechanical rear differential lock, which offers enhanced traction on firm surfaces but limits performance in slippery conditions. Equipped with a planetary final drive and hydraulic wet disc brakes, the tractor ensures reliable power transfer and effective stopping power, though the lack of a fully enclosed cab may expose the operator to the elements. The 8-speed collar shift transmission, along with options for power shift, provides flexibility for various applications, making it suitable for moderate agricultural tasks, but its open operator station may reduce comfort during longer working hours.
