ENGINE DETAIL
The Zetor 6748 is powered by a 3.5L, 4-cylinder diesel engine that produces 65hp at a rated RPM of 2200, offering a good balance of power for medium-duty tasks. Its bore and stroke design (100mm x 110mm) allows for efficient torque delivery, which can enhance performance in agricultural applications, such as plowing or towing. However, with relatively lower horsepower compared to competitors, it may face challenges in heavy-duty operations, making it more suited for small to medium farms or specialized applications.

TRANSMISSION 1
The Zetor 6748 features a 10-speed forward and 2-speed reverse transmission, allowing for versatile speed control and efficient power management in various agricultural tasks. This gearbox configuration provides an optimal balance between speed and torque, enhancing performance in both fieldwork and transport scenarios. However, operators may need to adapt to the more complex shifting process compared to tractors with simpler transmission systems.
| Gears | 10 forward and 2 reverse |
TRANSMISSION 2
The Zetor 6748 features a partial power shift transmission, allowing seamless shifting between 20 forward and 4 reverse gears, enhancing operational flexibility. The optional multi-power transmission is advantageous in varying terrain, providing two-speed options for direct drive or lower range, ideal for efficient plowing or transport tasks. However, mastering the shifting mechanism can pose a learning curve for operators unfamiliar with multi-power systems.
