TRANSMISSION
The Oliver 660 tractor features an unsynchronized transmission with 6 forward and 2 reverse gears, which can enhance simplicity in operation but may require careful shifting to avoid grinding gears. The unsynchronized design can pose challenges in quick gear changes, making it less suitable for tasks requiring frequent speed adjustments. This tractor is ideal for steady fieldwork or applications with consistent speed requirements but might not perform optimally in racing or high-agility scenarios.
