TRANSMISSION
The Zetor Major HT 55 features a hydrostatic transmission, allowing for smooth and precise speed control, making it ideal for tasks requiring variable speed, such as loader work. With infinite gears across a 3-range system for both forward and reverse, this tractor can excel in a variety of farming applications, although it may limit top speed compared to traditional gear-driven models. The oil capacity of 9.2 quarts ensures adequate lubrication for extended operational periods, but regular monitoring is essential to prevent overheating and maintain performance.

MECHANICAL
The Zetor Major HT 55 features a 4x4 MFWD (Mechanical Front-Wheel Drive) chassis, providing enhanced traction on varied terrains, which is advantageous for diverse agricultural tasks. Its power steering and wet disc brakes improve maneuverability and stopping performance, ensuring operator comfort and safety. The hydrostatic transmission offers smooth speed control, making it ideal for precise operations like planting and tillage; however, it may require more maintenance compared to gear-driven systems.

ZETOR MAJOR HT 55 TIRES
The Zetor Major HT 55 tractor is equipped with standard agricultural tires (9.5-16 front, 13.6-26 rear), which provide good traction in field operations but may limit performance on paved surfaces. The optional industrial tires (12-16.5 front, 17.5L-24 rear) enhance stability and load-bearing capacity, making it suitable for material handling or construction tasks. Consider the intended application; agricultural tires excel in farming conditions, while industrial tires are beneficial for versatility in mixed environments.
