Engine Type:
Diesel Engine (Specifics vary by sub-model, typically Zetor's in-line 4-cylinder diesel engines)
Estimated Horsepower Range:
Approximately 80-120 HP (depending on specific 80xx vs 120xx models)
Cooling Method:
Water-Cooled
Engine Family:
Likely Zetor's Z Series engine platform (e.g., Z 7701 series engines or similar variants)
Transmission Type:
Manual Synchromesh Gearbox (likely with multiple speed ranges and gears)
Optional Features:
Possible creeper gears, or enhanced PTO options.
Power Take Off:
Standard PTO operation, likely with multiple speeds (e.g., 540/1000 RPM).
Operating Weight:
Varies by model and configuration, typically in the range of 3,500 - 5,000 kg
Front Axle Load Capacity:
Design specific, crucial for 4WD models (8045, 12045)
Rear Axle Load Capacity:
Design specific, rated for implement loads and traction.
Instrumentation:
Basic analog gauges for engine RPM, coolant temperature, oil pressure, fuel level, and hours meter. Warning lights for essential functions.
Operator Controls:
Mechanical linkage for transmission shifting, hydraulic lever controls for implement operation.
Power Take Off Control:
Manual engagement lever, potentially with a mechanical speed selector.
Engine Oil Change:
Typically 250-300 hours, depending on operating conditions.
Hydraulic Fluid Change:
Typically 500-1000 hours, check filter replacement interval.
Engine Oil Type:
API CD or CE rated diesel engine oil, viscosity grade like 15W-40 or 10W-30 depending on ambient temperature.
Hydraulic Fluid Type:
Tractor Hydraulic Fluid (THF) or Universal Tractor Transmission Oil (UTTO) meeting relevant specifications (e.g., ISO VG 46).
Coolant Type:
Ethylene glycol-based antifreeze with corrosion inhibitors, mixed 50/50 with water for a typical temperature range.
Common Wear Items:
Clutch wear, PTO bearing failures, hydraulic pump leaks, starter motor issues, common with tractors of this era.
Electrical Corrosion:
Potential for wiring harness degradation and terminal corrosion due to age and environmental exposure.
Fuel System Maintenance:
Regular fuel filter replacement and bleeding of the fuel system are crucial for reliable starting and operation.
Manufacturer Origin:
Czechoslovakia (now Czech Republic)
Production Era:
Likely produced from the late 1970s through the 1980s, representing Zetor's mid-range utility tractors.
Manufacturing Plant:
Zetor Tractors, Brno, Czechoslovakia
