TRANSMISSIONS OVERVIEW
The Zetor 4340 tractor features a 10-speed synchro transmission, providing efficient gear shifting for various field operations. This allows for enhanced torque delivery and improved fuel efficiency, ideal for both agricultural tasks and transport applications. However, the complexity of the synchro system may require more maintenance compared to simpler transmission types.
| Description | 10-speed synchro 10-speed |
TRANSMISSION 1
The Zetor 4340 features a synchro gearbox that provides 10 forward and 2 reverse gears, allowing for versatile speed adjustments suited for various agricultural tasks. The hydraulic cerametallic disc clutch, with a diameter of 304.8mm, offers enhanced durability and efficient power transfer, which is advantageous for heavy towing and rugged field conditions. However, the synchro transmission may present challenges in more demanding terrains, where synchronized shifting is critical to maintain optimal engine performance.

| Description | With 16.9-28 rear tires |
TRANSMISSION 2
The Zetor 4340 features a mechanical shuttle transmission with 10 forward and reverse gears, providing enhanced control and versatility for various agricultural operations. The mechanical shuttle allows for smooth direction changes without clutching, beneficial for tasks requiring frequent reversals, such as front-end loader work. However, operators may need time to adapt to the gear patterns, especially in high-stress situations or when maneuvering in tight spaces.
