The Fendt 309 CI carries a water-cooled four-cylinder diesel engine with 4,038 cm³ of displacement, producing 105 hp, or 76.9 kW, at 2,300 rpm, with 474 Nm of torque; it runs on diesel or RME. At 4,220 kg, 4,000 mm long, 2,710 mm high, 2,140 mm wide and with a 2,280 mm wheelbase, the machine reaches a top speed of 40 km/h.
At 76.9 kW from 4,038 cm³ of displacement, the 309 CI sits between compact yard and front-loader tractors and the large farm tractors, and suits versatile field work with medium-weight implements as well as haulage on medium-sized farms. The 40 km/h design top speed falls under German driving licence class T.
When buying used, the condition of the clutch and gearbox matters, along with the tightness of the hydraulic connections for front and rear implements and the condition of the cooling system, whose hoses and radiator can become brittle or leak after many years of service. Also worth checking is corrosion damage to the frame and mudguards, common on machines of this age, along with the condition of the tyres, the function of the lighting system, and play in the steering linkage after years of yard and field use.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Check the weights in the papers against the figures here — attachments change them.
- Check front and rear tyre sizes: mismatched pairs strain the drivetrain.
- Shift the gearbox cold and warm — jumps only show up at temperature.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
