TRANSMISSIONS OVERVIEW

The LS MT357 tractor features a 16-speed synchro shuttle hydrostatic transmission, which allows for seamless transitions between forward and reverse without clutch engagement, enhancing operator efficiency and control. The hydrostatic design provides variable speed control, making it advantageous for tasks requiring precise maneuverability, such as loader work in tight spaces. However, it may have higher maintenance demands compared to traditional gear transmissions, and thermal management is critical during prolonged use to prevent performance degradation.

16-speed synchro shuttle hydrostatic

TRANSMISSION 1

The LS MT357 features a synchro shuttle transmission with 16 forward and reverse gears, allowing for smooth and efficient direction changes, which is advantageous for applications requiring frequent movement such as loader work or tilling. The design enhances control during operation, reducing operator fatigue by enabling seamless shifting. However, mastering gear selection in varying terrain can present a learning curve for new operators.

Type	synchro shuttle
Gears	16 forward and reverse

TRANSMISSION 2

The LS MT357 features a hydrostatic transmission, providing seamless and infinite speed control across its three-range system, enhancing maneuverability during intricate tasks. However, hydrostatic systems can generate more heat, potentially leading to shorter lifespan if not properly maintained. Ideal for applications requiring precise speed and directional control, such as mowing or loader work.

Type	hydrostatic
Gears	infinite (3-range) forward and reverse

MECHANICAL

The LS MT357 tractor features a robust 4x4 MFWD design, providing excellent traction and stability for various terrain types, ideal for agricultural tasks. Its power steering enhances maneuverability, while the wet disc brakes ensure effective stopping even in demanding conditions, increasing operator safety. The optional cab offers added comfort and protection, and the 16-speed synchro shuttle/hydrostatic transmission allows for flexible speed control, optimizing performance during both transport and fieldwork scenarios.
