The water-cooled six-cylinder diesel engine of 5,867 cc produces 120 hp (87.8 kW) at 2,200 rpm. At an unladen weight of 4,450 kilograms, a wheelbase of 2,560 millimetres and a width of 2,088 millimetres, this is a powerful, heavy standard tractor for drawbar work with high power demand.
With a design top speed of 32 km/h, the machine falls under driving licence category T. A six-cylinder engine of this size was designed for sustained ploughing and cultivation work and ran more smoothly than smaller four-cylinder models of comparable output. The power take-off on tractors of this kind runs at the standard speed of 540 or 1,000 rpm.
When buying a 1246, checks should include the injection pump and its six injectors, as well as the condition of the clutch and gearbox on a tractor that may have spent decades in heavy drawbar work. Corrosion on the frame and load-bearing sheet-metal parts and the tightness of the hydraulics are especially important given this weight. On such a heavy tractor, the brakes and the steering hydraulics also deserve particular attention.
