The water-cooled six-cylinder diesel engine of 5,867 cc produces 100 hp (73.5 kW) at 2,100 rpm and 365 Nm of torque. At an unladen weight of 3,950 kilograms, a wheelbase of 2,590 millimetres and a width of 2,098 millimetres, the 1046 is a powerful standard tractor of its time.
With a design top speed of 30 km/h, the machine falls under driving licence category T. A six-cylinder engine of this displacement typically ran more smoothly and with less vibration than the four-cylinder models offered at the same time, and was designed for drawbar work with high power demand. The power take-off on tractors of this kind runs at the standard speed of 540 or 1,000 rpm, so that mounted implements fit regardless of manufacturer.
When buying a used 1046, checks should include the condition of the injection pump and its six injectors, as well as corrosion on the radiator grille and wings. Gearbox and hydraulic oil levels, the condition of the clutch disc and the tightness of the crankshaft seals are typical weak points on a six-cylinder engine of this age. On such a heavy tractor, the brakes and the steering hydraulics also deserve particular attention.

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.
