MECHANICAL
The Leader 25-40 tractor features a half-track chassis, providing enhanced traction and stability on uneven terrains, making it suitable for muddy or loose conditions. The manual steering system, while offering direct control, may require more physical effort in tight maneuvering scenarios compared to modern assisted steering systems. With a 2-speed gear transmission, this tractor allows for flexibility in speed adjustment, beneficial for both fieldwork and transport but may limit performance in precision tasks at lower speeds.
