ENGINE DETAIL
The Zetor 8020 features a robust turbocharged 4-cylinder diesel engine with a displacement of 4.2L, providing 82hp at a rated RPM of 2200, which is advantageous for both agricultural tasks and light industrial applications due to its efficient power output. The engine's bore and stroke design (105x120 mm) contributes to a good torque profile, enhancing performance in various field conditions. However, the reliance on a 12-volt electric starter may lead to challenges in extreme cold climates, where additional heating or battery management systems are advisable for reliable starting.

ZETOR 8020 ENGINE
The Zetor 8020 features a robust 4.2L 4-cylinder diesel engine, delivering reliable power for various agricultural tasks. With a combined fuel capacity of 56 gallons (211.9L) across the ROPS and cab tanks, it ensures extended operational periods, reducing downtime for refueling during intensive fieldwork. However, the tractor's weight distribution and handling could be a challenge when navigating uneven terrains; thus, operators should consider using front weights for better stability in hilly conditions.

MECHANICAL
The Zetor 8020 features a 4x2 2WD chassis, ideal for lighter agricultural tasks but may struggle in slippery conditions due to the lack of all-wheel drive; however, its mechanical rear differential lock can enhance traction when engaged. With a 12-speed synchronized transmission, it allows for smooth gear shifts, improving efficiency and operator control during fieldwork. The optional air-conditioned cab, combined with power steering, enhances operator comfort during extended use, making it a suitable choice for varied farming operations.

ZETOR 8020 TIRES
The Zetor 8020 features standard agricultural tires with front dimensions of 9.00-16 and rear dimensions of 16.9-30, providing a solid balance of traction and stability for various farming applications. The larger rear tires facilitate better weight distribution and improved flotation on softer soils, allowing for efficient field operations. However, one should consider potential challenges regarding maneuverability in tighter spaces due to the overall size of the tire setup.
