Introduction
Zetor 6745: A Mid-Range Agricultural Tractor
The Zetor 6745 is a four-wheel-drive agricultural tractor produced in Brno, Czechoslovakia, between 1972 and 1978. Designed for versatility and endurance, this model served as a core utility machine for diverse farming operations during the 1970s.
Engine and Power
The tractor is powered by the Zetor Z6701, a 4-cylinder, liquid-cooled diesel engine with a displacement of 3.5 liters (210.9 cubic inches). With a rated speed of 2200 RPM, it produces approximately 65 horsepower (48.5 kW). The engine design features a bore and stroke of 100 mm by 110 mm, prioritizing torque and reliability for field work.
Transmission and Drivetrain
The 6745 is equipped with a four-wheel-drive system to enhance traction in varied soil conditions. The standard transmission offers 10 forward and 2 reverse gears. An optional multi-power transmission was available, providing a two-speed partial power shift that expands the configuration to 20 forward and 4 reverse gears, allowing for smoother transitions between direct drive and a lower range.
Hydraulics and PTO
The tractor utilizes the Zetormatic hydraulic system, which provides a pump flow of 20.1 lpm (5.3 gpm) at a pressure of 160.0 bar (2321 psi). The rear lift capacity is rated at 1,749 kg (3,858 lbs). The independent rear PTO supports 540 RPM and ground-speed operations, with an optional 1000 RPM capacity available for specialized implements.
Mechanical and Dimensions
The unit features differential hydraulic drum brakes, with an optional air brake system for trailers. The tractor has a wheelbase of 224 cm (88.46 inches) and weighs 3,036 kg (6,695 lbs). It is configured with an open operator station and typically operates on 11.2-24 front and 12.4-36 rear agricultural tires.
Conclusion
The Zetor 6745 is a robust, mechanically straightforward tractor suited for general agricultural tasks, light tillage, and implement management. Its combination of four-wheel drive and flexible transmission options made it a durable solution for small to medium-sized farming operations during its production era.
