ENGINE DETAIL
The Zetor 7520 features a robust 4-cylinder diesel engine with a displacement of 4.2L, delivering 71hp at a rated RPM of 2200, ensuring sufficient torque for various agricultural tasks. The bore and stroke dimensions (105x120 mm) indicate a lower rev range with potentially higher torque output, making it ideal for heavy-duty applications like plowing or towing. However, the 12V starter system rated at 4.6hp may limit cold weather performance, necessitating additional attention during harsh conditions.

TRANSMISSIONS OVERVIEW
The Zetor 7520 features a 16-speed or optional 18-speed synchromesh transmission, providing a wide range of gear ratios for optimal power management across various field conditions. This transmission design enhances ease of operation and reduces gear shifting effort, beneficial for both heavy and precision tasks. However, the complexity of the synchromesh system may require more maintenance and servicing compared to simpler transmission types, potentially impacting long-term operational costs.
| Description | 16-speed/18-speed synchromesh |
TRANSMISSION 1
The Zetor 7520 features a 16 forward and 4 reverse gear configuration, providing versatility for various agricultural tasks. This extensive range can enhance efficiency in maneuverability, allowing for optimized speed control in different terrains. However, the complexity of the transmission may require more frequent operator training to maximize its potential.
| Gears | 16 forward and 4 reverse |
TRANSMISSION 2
The Zetor 7520 features a synchromesh transmission with 18 forward and 6 reverse gears, offering enhanced shifting smoothness and operational efficiency. The inclusion of a three-speed torque multiplier allows for increased torque across various operational scenarios, making it suitable for diverse tasks such as heavy tilling or transportation. However, operators may need time to acclimate to the complexity of gear selection, potentially increasing initial learning curves.
