ENGINE DETAIL 1
The John Deere 520 tractor features a liquid-cooled, 2-cylinder gasoline engine with a displacement of 189.8 cubic inches, providing a suitable power output for light agricultural tasks. With a low compression ratio of 7:1 and a rated RPM of 1325, this tractor is optimized for torque rather than high-speed operations, making it ideal for plowing or hauling. The oil bath air cleaner ensures better engine longevity, while the 12-volt starter system simplifies starting in various conditions, though maintenance of the oil bath filter may be seen as a challenge for some operators.

JOHN DEERE 520 TRANSMISSION
The John Deere 520 tractor features a 6-speed unsynchronized transmission, which provides reliable gear shifting but may require more operator skill for smoother transitions between gears. The unsynchronized design can lead to increased wear on the transmission components if not operated correctly, making proper maintenance critical. This tractor is well-suited for basic agricultural applications where gear efficiency is essential but may face challenges in high-speed operations compared to synchronized equivalents.
