The Zetor Major HT 45 is a utility tractor introduced in 2017, designed for versatile agricultural and maintenance tasks. It features a compact design and is equipped with a modern diesel powertrain, making it suitable for small to mid-sized farming operations requiring reliable performance.
Engine and Performance
The tractor is powered by a Yanmar 4TNV88C liquid-cooled, 4-cylinder diesel engine. With a displacement of 2.2 liters, it generates a gross power output of 46 hp at a rated speed of 2800 RPM. The engine complies with Tier IV emission standards to meet current environmental regulations.
Transmission and Drivetrain
The drivetrain utilizes a hydrostatic transmission, providing the operator with infinite forward and reverse speeds across three distinct ranges. This configuration allows for smooth speed adjustments without manual clutching, enhanced by a standard four-wheel drive system for improved traction. Steering is power-assisted, and braking is handled by wet disc brakes.

The rear power take-off (PTO) is independent, operated by an electro-hydraulic clutch, and runs at a speed of 540 RPM.
Hitch and Dimensions
The Major HT 45 features a Category I rear hitch with position and draft control. It offers a lifting capacity of 3,314 lbs (1,503 kg) at the ends, and 2,945 lbs (1,335 kg) at 24 inches behind the lift point. The machine has a wheelbase of 76.2 inches and an operating weight of 4,233 lbs, ensuring stability across varied terrain.
Operator Environment
The tractor comes equipped with a factory-installed cab as standard, featuring air conditioning to maintain operator comfort in diverse weather conditions. The electrical system is powered by a 12V battery and a 70-amp alternator.
Conclusion
The Zetor Major HT 45 is a well-balanced utility tractor tailored for operators who require a maneuverable, comfortable, and efficient machine for daily agricultural duties.
