TRANSMISSION
The Oliver Super 55 features an unsynchronized gear transmission with 6 forward and 2 reverse gears, which may lead to challenges in shifting under load. The dry plate clutch offers efficiency in power transfer but can experience wear with frequent engagement and disengagement. This setup is ideal for moderate field tasks but may require experienced operators to manage gear shifts effectively.

OLIVER SUPER 55 TRANSMISSION
The Oliver Super 55 features a 6-speed unsynchronized transmission, which allows for straightforward operation but may require a skilled operator for smooth shifting between gears, especially under load. Advantages include versatility for various applications, but the unsynchronized nature could lead to increased wear on components if not managed properly. Operators might encounter challenges in frequent gear changes during plowing or heavy towing, highlighting the importance of proper technique for efficient performance.
