ZETOR 25K POWER
ENGINE DETAIL
The Zetor 25K, with its 2-cylinder liquid-cooled diesel engine and a displacement of 2.1 L, provides a power output of 25 hp at a rated RPM of 1800, making it efficient for light to moderate agricultural tasks. The 18:1 compression ratio enhances fuel efficiency and torque characteristics, which is advantageous for operations requiring sustained power but can present challenges in cold starts without proper management. Given its compact size and relatively modest power, this tractor is ideal for small farms or specialized applications like vegetable farming or landscaping, where maneuverability and fuel economy are crucial.

ZETOR 25K ENGINE
The Zetor 25K features a robust 2.1L, 2-cylinder diesel engine, providing reliable torque output suitable for various agricultural tasks. Its fuel tank capacity of 11.9 gallons (45.0 liters) allows for extended operational time in the field, reducing the frequency of refueling during intensive work periods. However, the smaller engine size may limit performance under heavier loads compared to larger tractors, making it ideal for light to moderate farming duties.

TRANSMISSION
The Zetor 25K features a 6 forward and 2 reverse gear system, which provides a balanced range for various field operations and allows for a maximum speed of approximately 25 km/h. The dry disc clutch offers durability and requires lower maintenance compared to wet clutches, but may result in harsher engagement under heavy loads. Ideal for small to medium agricultural tasks, the gear configuration supports efficient maneuverability in tight spaces while the clutch type ensures straightforward operation in diverse conditions.

MECHANICAL
The Zetor 25K features a 4x2 2WD chassis, offering adequate traction for light-duty tasks on flat terrain, but may struggle on inclines or muddy surfaces. Its open operator station enhances operator visibility and accessibility, although it lacks protection from inclement weather. The 6-speed transmission provides versatility in speed selection, making it suitable for various agricultural applications, yet it may require more frequent gear shifting compared to models with hydrostatic or powershift transmissions.

ZETOR 25K TIRES
The Zetor 25K tractor's front and rear tire specifications (5.50-16 and 9-36/13-28, respectively) provide a good balance of traction and stability, suitable for light to medium agricultural tasks. The smaller front tire enhances maneuverability while the larger rear tire supports better load distribution and traction in fields. However, operators may face challenges with soil compaction and maintenance on uneven terrain due to the tire sizes, necessitating careful management to optimize performance in varying conditions.
