TRANSMISSIONS OVERVIEW
The Zetor 8520 features a robust 16-speed synchromesh transmission, providing smooth gear shifting and enhancing operational efficiency, especially in varying field conditions. This transmission system can lead to lower engine RPM at cruising speed, improving fuel economy and reducing wear on drivetrain components. However, the complexity of the synchromesh may require more maintenance compared to simpler gear systems, which could be a consideration for users in remote agricultural settings.

TRANSMISSION 1
The Zetor 8520 tractor features a 16 forward and 4 reverse gear transmission, providing versatile speed options for various agricultural tasks. This extensive gearing allows for precise control in both high-torque applications like plowing and quicker movements when transporting loads. However, the complexity of the gearbox might present a learning curve for operators unfamiliar with multi-range transmissions, potentially impacting productivity during initial use.
| Gears | 16 forward and 4 reverse |
TRANSMISSION 2
The Zetor 8520 features a synchromesh transmission with 18 forward and 6 reverse gears, allowing for smooth shifting and optimal torque management. The three-speed torque multiplier enhances efficiency in varying load scenarios, making it suitable for both light and heavy-duty tasks. However, the complexity of the gear system may require more maintenance and operator familiarity to maximize its potential.
