TRANSMISSION
The Zetor 5545 features a 10-speed forward and 2-speed reverse gearbox, providing versatility for various agricultural tasks and enabling efficient speed management for different field conditions. Its dry disc clutch offers reliable engagement but may require more frequent adjustments and maintenance compared to a wet clutch, particularly under heavy-load scenarios. Overall, this tractor is well-suited for general farming operations, though operators should be prepared for the maintenance needs associated with its clutch system.

MECHANICAL
The Zetor 5545's 4x4 MFWD system enhances traction, making it suitable for diverse terrains and conditions, particularly in agricultural applications. Its mechanical rear differential lock provides improved control in challenging conditions, although manual steering may require substantial effort during prolonged use. The 10-speed transmission allows for versatility in speed management, but the open operator station can expose the driver to weather elements, potentially impacting comfort over extended periods.

ZETOR 5545 TIRES
The Zetor 5545 tractor, equipped with Ag front tires (8-24) and Ag rear tires (13-28), provides a balanced power-to-weight ratio, enhancing maneuverability and traction for field operations. The larger rear tires improve load capacity and soil protection, but may raise the center of gravity, potentially affecting stability on inclines. This configuration is ideal for medium-sized farms requiring versatile performance in plowing, tilling, and transport tasks.
