A Czech-Built Workhorse with Global Reach
The Zetor 5911 was part of the Unified Series I lineup produced by Zetor in Brno, Czechoslovakia during the early 1970s. Known for its mechanical simplicity and rugged construction, the 5911 featured a naturally aspirated four-cylinder diesel engine rated at approximately 60 horsepower. It was designed for small to mid-scale agricultural operations and became popular across Europe, especially in Ireland, Poland, and the Balkans. Zetor’s reputation for building affordable, repairable tractors helped the brand expand into over 100 countries by the late 1970s.
Engine and Transmission Characteristics
The Zetor 5911 used the Zetor Z5701 engine, a direct-injection diesel with a dry sleeve design. It was paired with a 10-speed transmission—five forward gears with a high/low range selector. The gearbox was fully mechanical, with no hydraulic shuttle or synchronized gears, requiring deliberate clutching during shifts.
Key specifications:
Restoring a 1972 Zetor 5911 often begins with sourcing a repair manual. These manuals include exploded diagrams, torque specifications, and wiring schematics essential for engine and hydraulic work. In Ireland and other regions, original manuals may be scarce, but reprints and digital versions are available through European auction sites and vintage tractor forums.
Common restoration tasks include:
Parts Availability and Compatibility
Zetor’s modular design means many parts from the 5911 are shared with the 5011, 6711, and 6911 models. This includes:
Preserving Legacy and Functionality
Restoring a Zetor 5911 is not just a mechanical task—it’s a tribute to a tractor that helped mechanize farms across post-war Europe. With proper care, these machines can still plow, mow, and haul with confidence. Owners are encouraged to:
The Zetor 5911 remains a symbol of durable, democratic engineering. Its restoration offers both practical utility and historical satisfaction. With a repair manual in hand and a bit of patience, this 1972 tractor can return to the field—ready to work, teach, and endure.

Key specifications:
- Engine displacement: 3.1 liters
- Rated RPM: 2200
- Fuel tank capacity: 60 liters
- PTO power: ~50 hp
- Rear lift capacity: ~1600 kg
- Dry Sleeve: A replaceable cylinder liner that does not contact coolant directly, simplifying rebuilds.
- PTO (Power Take-Off): A rotating shaft at the rear of the tractor used to power implements.
- High/Low Range Selector: A lever that doubles the number of available gears by switching between two gear ratios.
- Unified Series: Zetor’s modular design philosophy allowing parts interchangeability across models.
Restoring a 1972 Zetor 5911 often begins with sourcing a repair manual. These manuals include exploded diagrams, torque specifications, and wiring schematics essential for engine and hydraulic work. In Ireland and other regions, original manuals may be scarce, but reprints and digital versions are available through European auction sites and vintage tractor forums.
Common restoration tasks include:
- Replacing fuel lines and filters
- Rebuilding the injector pump and injectors
- Servicing the clutch and adjusting pedal free play
- Rewiring the dashboard and lighting circuits
- Replacing hydraulic seals in the lift arms and control valve
Parts Availability and Compatibility
Zetor’s modular design means many parts from the 5911 are shared with the 5011, 6711, and 6911 models. This includes:
- Engine components (pistons, liners, valves)
- Transmission gears and bearings
- Hydraulic lift arms and control valves
- Electrical switches and gauges
Preserving Legacy and Functionality
Restoring a Zetor 5911 is not just a mechanical task—it’s a tribute to a tractor that helped mechanize farms across post-war Europe. With proper care, these machines can still plow, mow, and haul with confidence. Owners are encouraged to:
- Use modern low-sulfur diesel with additive conditioners
- Grease all pivot points monthly
- Change engine oil every 100 hours
- Flush the cooling system every two years
