Engine Type:
Likely Fiat-designed naturally aspirated diesel engines (specific displacement and cylinder count would require model-specific data).
Horsepower Range:
Typically in the 50-70 HP range for this class of tractor, specific figures vary by exact model and engine variant.
Torque Characteristics:
Designed for robust low-end torque delivery crucial for agricultural applications.
Injection Type:
Mechanical diesel injection system (likely rotary or inline pump).
Cooling Method:
Liquid-cooled, typically with a radiator, fan, and thermostat.
Oil Type Specification:
Refer to manual for specific SAE viscosity grade (e.g., SAE 15W-40) and API service classification (e.g., API CD/CE).
Gearbox Type:
Manual transmission, likely with a range of forward and reverse gears.
Transmission Options:
While not explicitly stated, some models might have offered PTO options or creeper gears.
P T O Systems:
Likely rear PTO, potentially with multiple speed options (e.g., 540/1000 RPM).
Drive Configuration:
DT variants indicate Dual Traction, meaning 4-wheel drive capability.
Transmission Fluid:
Refer to manual for specific GL classification (e.g., GL-4 or GL-5) and viscosity grade for gearbox and hydraulic systems.
General Configuration:
Standard agricultural tractor layout with engine at the front, transmission and drive components mid-chassis, and operator station at the rear.
Operating Weight:
Specific weight varies by configuration but typically within the 2000-3000 kg range for this tractor class.
Towing Capacity:
Refer to specific model documentation, but designed for substantial towing and implement operation.
Rollover Protection:
ROPS (Roll Over Protective Structure) is standard or an option on tractors of this era. Manual will detail safety procedures.
Safety Interlocks:
PTO safety switches, transmission safety neutral, brake interlocks.
Lighting And Signaling:
Headlights, taillights, turn signals (if equipped), hazard warning lights.
Instrumentation:
Basic instrumentation likely including engine temperature gauge, oil pressure light/gauge, ammeter/voltmeter, tachometer, and hour meter.
Control Systems:
Mechanical linkages for transmission, PTO engagement, and hydraulic controls. Power steering may be present on some variants.
Lighting Controls:
Manual switches for headlights, work lights, and indicators.
Engine Oil Change:
Typically every 250-500 operating hours, refer to manual for exact interval and oil specification.
Fuel Filter Replacement:
Recommended at regular intervals or when issues arise, consult manual for specifics.
Air Filter Maintenance:
Service based on operating conditions, frequent checks in dusty environments, refer to manual for replacement intervals.
Engine Coolant:
Refer to manual for type (e.g., ethylene glycol-based) and mix ratio with water, and capacity.
Hydraulic Fluid:
Refer to manual for specific hydraulic fluid type (e.g., Universal Tractor Transmission Oil - UTTO, or dedicated hydraulic oil) and capacity.
Common Wear Points:
Clutch wear, hydraulic system leaks, PTO clutch engagement, cooling system performance, electrical connections.
Preventative Measures:
Regular lubrication, checking fluid levels, keeping air intake clean, inspecting for leaks, and timely filter changes.
Fiat Agri Legacy:
Fiat Tractors has a long history of producing reliable and robust agricultural machinery, with the 580-680 series representing part of their mid-range offerings from the late 20th century.
Series Placement:
These models were part of Fiat's comprehensive tractor line, designed to meet the needs of various agricultural operations, from small farms to larger estates.
Production Era:
Likely produced in the 1970s or 1980s, though exact years are not specified in the product information.
