Introduction
Zetor 8620 Row-Crop Tractor
The Zetor 8620 is a row-crop tractor produced between 1989 and 1999 in Brno, Czech Republic. Designed for versatile agricultural operations, this machine belongs to the 8640 series and offers a balance of mechanical simplicity and field performance.
Engine and Performance
The tractor is powered by the Zetor Z 1201, a 4-cylinder, liquid-cooled diesel engine with a displacement of 4.2 liters (254 ci). It utilizes a direct injection fuel system and is rated at 82 hp (61.1 kW) at 2200 RPM. The engine incorporates glow plugs for reliable cold-weather starting and is supported by a 12-volt electrical system.
Transmission and Drivetrain
The Zetor 8620 features a synchromesh transmission providing 18 forward and 6 reverse gears. This system includes three gears across high, low, and reverse ranges, enhanced by a three-speed torque multiplier. Power is transferred via a 330mm hydraulic dry disc clutch to the two-wheel drive system.
Hydraulics and Hitch
Equipped with an open-center hydraulic system, the tractor provides a pump flow of 16 gpm (60.6 lpm) at a pressure of 2600 psi (179.3 bar), operating three valves. The rear hitch is a Category II type with position and draft control, capable of lifting up to 9000 lbs (4082 kg). An independent rear PTO is standard, offering 540/1000 RPM speeds.
Operator Environment and Chassis
The operator is housed in a standard cab, with air conditioning available as an option. The machine is steered via a power steering system and utilizes hydraulic wet disc brakes for stopping power. An electro-hydraulic rear differential lock is included to improve traction in varying field conditions.
Conclusion
With its robust 4.2-liter engine and significant lift capacity, the Zetor 8620 is suited for row-crop applications and general farm tasks. Its combination of a synchromesh transmission and hydraulic capabilities makes it a dependable workhorse for operators requiring consistent performance in a 80-hp class machine.
