Water-cooled, with specifications for coolant type and capacity.
Gearbox Type:
Likely a multi-speed manual gearbox, potentially with synchronized gears. Details on gear ratios would be present.
Differential Lock:
The 'DT' designation indicates a 'Dual Traction' or 4WD variant, implying a front-wheel drive axle and potentially a locking differential.
Fluid Type:
Manual would specify the correct transmission and hydraulic fluid (often a universal tractor transmission fluid - UTF) and its specifications.
Wheelbase:
Specific wheelbase dimensions for 2WD and 4WD variants would be included in the manual.
Overall Length:
Manual will provide overall length measurements.
Overall Width:
Manual will provide overall width measurements, potentially varying with tire fitment.
Operating Weight:
The manual will specify the operating weight and potentially the weight distribution.
Braking System Description:
Details on the mechanical and hydraulic aspects of the braking system, including potential modifications for different operating conditions.
Rollover Protection:
While not always standard on older tractors, the manual might cover installation or maintenance of ROPS (Roll-Over Protective Structures) if applicable to this model's era or options.
Instrumentation:
Description of dashboard instruments and warning lights (e.g., oil pressure, temperature, battery charge).
Pto Controls:
Operation and maintenance of the PTO engagement and speed controls.
Hydraulic Controls:
Operation of the tractor's hydraulic lift system and remote hydraulic outlets (if equipped).
Engine Oil Change Interval:
Manual will specify recommended hours or time intervals for engine oil and filter changes.
Transmission Oil Change Interval:
Manual will outline service intervals for transmission and hydraulic fluid.
Engine Oil Viscosity:
Would specify recommended SAE viscosity grades (e.g., SAE 15W-40) and API service classifications for diesel engine oil.
Hydraulic Fluid Type:
Specifies the correct type of hydraulic fluid, often UTF (Universal Tractor Transmission Fluid) meeting specific standards.
Coolant Type:
Details on the appropriate coolant mixture and type (e.g., ethylene glycol based).
Common Wear Points:
Manual may allude to or provide repair procedures for common wear items like clutch wear, hydraulic pump wear, or PTO shaft issues.
Greasing Points:
Identification and servicing intervals for all grease points (e.g., kingpins, U-joints, linkage).
Manufacturer:
Fiat Trattori (later became part of CNH Industrial)
Production Period:
The Fiat 680 series was produced likely in the 1970s and early 1980s, representing a mid-range tractor for agricultural applications.
Tractor Segment:
Designed for a variety of agricultural tasks, suitable for medium to large farms.
