Engine Type:
Zetor diesel engines (specific model variants will depend on the exact tractor configuration, likely inline 4-cylinder or 6-cylinder naturally aspirated or turbocharged diesel).
Horsepower Range:
Typically between 80 HP for the 80-series and 120 HP for the 120-series, though specific power outputs may vary.
Torque:
Specific torque figures vary by engine and configuration, detailed within the manual.
Fuel Injection:
Mechanical direct injection system, likely with distributor or inline injection pumps (e.g., Zetor, LIAZ, or other European manufacturers).
Cooling Method:
Water-cooled with a thermostat-controlled circulation system and a radiator.
Gearbox Type:
Manual synchronized or unsynchronized transmission with multiple gears (e.g., 10-speed forward, 2-speed reverse, or more complex options like a creeper gear or synchronized splitter).
Powershift:
While less common on these specific models, some variations might have offered optional powershift ranges or a torque amplifier.
Pto:
Standard rear PTO, likely with multi-speed options (e.g., 540/1000 RPM), and potentially a ground-speed PTO.
Differential Lock:
Mechanical front and/or rear differential lock engagement.
Wheelbase:
Specific dimensions vary by model (e.g., 8011/8045 vs. 12011/12045), detailed in the manual.
Overall Length:
Varies by model configuration.
Unladen Weight:
Typically in the range of 4000-6000 kg, depending on the model and specific configuration (2WD/4WD).
Max Gross Weight:
Detailed in the manual, will be significantly higher than unladen weight.
Rollover Protection:
Depending on year of manufacture and region, ROPS (Roll-Over Protective Structure) may be standard or optional. Manual will cover its inspection and maintenance.
Braking System:
Hydraulically operated, typically disc brakes on front and rear axles (or drum brakes on older versions). Manual covers adjustment and servicing.
Seatbelts:
Seatbelt inspection and maintenance if equipped.
Dashboard Controls:
Basic analog instrumentation for engine RPM, oil pressure, coolant temperature, fuel level, and ammeter/voltmeter. Manual explains gauge functions and troubleshooting.
4Wd System:
For 4WD models (8045, 12045), the manual covers operation, maintenance, and potential issues with the front drive axle engagement.
Pto Control:
Manual lever or electronic engagement for PTO operation.
Engine Oil:
Typically every 250-500 operating hours, depending on operating conditions. Manual provides exact intervals and oil type.
Air Filter:
Regular inspection and cleaning/replacement, particularly in dusty environments. Manual details intervals and procedures.
Fuel Filter:
Periodic replacement, usually recommended annually or based on operating hours. Manual specifies interval and filter part numbers.
Engine Oil:
Typically SAE 15W-40 or 20W-50 diesel engine oil (API CD/CE or higher). Manual confirms exact specification and capacity.
Transmission Hydraulic Fluid:
Often a universal tractor transmission oil (UTTO) or a specific Zetor-approved hydraulic oil. Manual provides precise type and capacity.
Coolant:
Ethylene glycol-based antifreeze/coolant mixture. Manual specifies type and mixture ratio.
Electrical Gremlins:
Older Zetor models can sometimes experience issues with wiring integrity, switches, and connectors due to age and environmental exposure. The manual's electrical diagrams are crucial for troubleshooting.
Hydraulic Leaks:
Wear in hydraulic seals, pumps, and cylinders can lead to leaks. The manual provides procedures for seal replacement and pump overhaul.
Clutch Wear:
Normal wear and tear on clutch components requires adjustment and eventual replacement. The manual details clutch adjustment and replacement procedures.
Pto Engagement:
Issues with PTO engagement or operation can stem from linkage adjustments, clutch packs, or hydraulic control. The manual addresses these.
Origin:
Zetor is a well-established Czechoslovakian (now Czech Republic) manufacturer of agricultural machinery, known for robust and durable tractors.
Series:
The 80xx and 120xx series likely represent advancements in Zetor's tractor line, building on previous generations. These models often featured improved ergonomics, power, and transmission options.
Era:
These models were likely produced during the late 20th century and early 21st century.
