Engine Family:
Zetor (likely Z-series diesel engine)
Displacement:
Specific displacement not provided, but Zetor 4-cylinder engines of this era often ranged from 3.5L to 4.5L (e.g., Zetor 5201 or similar base engine)
Cooling System:
Liquid-cooled (typically thermosiphon or forced circulation)
Horsepower:
Estimated 45-55 HP (typical for this class of Zetor tractor)
Torque:
Specific torque figures not provided, but designed for agricultural applications
Injection Type:
Direct injection (likely with mechanical injection pump, e.g., Zetor or potentially licensed from a German manufacturer like Bosch or Lucas)
Fuel Filter:
Serviceable diesel filter (specific part numbers would be in the manual)
Type:
Mechanical, constant mesh gearbox
Gear Configuration:
Likely a 10-speed (e.g., 8 forward + 2 reverse) or 16-speed (e.g., 12 forward + 4 reverse) with a dual-range selector or creeper gears
Features:
Possible options may have included creeper gears or specific PTO speed configurations, but not a distinctly different transmission type
Clutch Type:
Single dry plate clutch (likely operated by a foot pedal)
Lubrication:
Gearbox oil (specific grade and capacity would be detailed in the manual, likely a GL-4 or GL-5 type gear oil)
Wheelbase:
Estimated 2000-2200 mm (typical for this class)
Overall Length:
Estimated 3500-4000 mm
Overall Width:
Estimated 1700-2000 mm (depending on tire fitment)
Operating Weight:
Estimated 2000-2500 kg
Front Axle Load:
Specific figures not available, but designed for weight distribution with rear implements
Rear Axle Load:
Specific figures not available, designed to carry significant implement weight
Rollover Protection:
ROPS (Roll Over Protection Structure) was often an option or aftermarket addition for tractors of this era. The manual would detail if it was integrated or an accessory.
Braking System Type:
Hydraulically actuated, typically drum brakes on the rear axle and possibly front axle in 4WD variants (4718 likely 4WD)
Parking Brake:
Mechanical parking brake acting on the drivetrain
Operator Station Design:
Designed for functional operation with safety considerations for the period, including guards for PTO and drivelines.
Features:
Basic operator controls, no advanced infotainment systems typically found on modern vehicles. May include basic gauges for engine temp, oil pressure, fuel level, and ammeter.
Features:
No driver assistance systems. Focus is on mechanical functionality.
Features:
No electronic connectivity features.
Engine Oil Change:
Typically 250-500 operating hours (specific interval would be in the manual)
Air Filter Service:
Service as needed based on operating conditions, replacement typically annually or at higher hour intervals
Fuel Filter Replacement:
Typically every 500-1000 operating hours or annually
Engine Oil:
Typically API CD/CE or similar, SAE 15W-40 or 10W-30 depending on climate (manual will specify exact grade and capacity)
Transmission Hydraulic Fluid:
Universal Tractor Transmission Oil (UTTO) or specific Zetor approved fluid, likely SAE 80W-90 for the gearbox and possibly a hydraulic fluid for the lift system (manual is critical for this)
Coolant:
Ethylene glycol-based antifreeze with corrosion inhibitors, typically a 50/50 mix with distilled water
Common Wear Items:
Clutch wear, hydraulic pump seals, PTO bearing wear, exhaust manifold leaks, electrical connector corrosion
