The M 963 (a) is powered by a three-cylinder diesel engine of 2,701 cm³ displacement, delivering 46.4 kW (63 hp) and 239 Nm of torque at 2,250 rpm. At an unladen weight of 2,490 kg, a wheelbase of 2,117 mm and a top speed of 30 km/h, the tractor is small and manoeuvrable, at a ratio of roughly 54 kg of weight per kW.
Three-cylinder engines of this displacement class are typical of compact all-purpose tractors handling narrow field access, orchard and vineyard work, or municipal tasks. Approval for rapeseed diesel alongside regular diesel fuel was not unusual for smaller tractors in the early 2000s. The short wheelbase gives a tight turning circle, a clear advantage over larger tractors on narrow field tracks and in row crops.
On a used M 963 (a), it is worth checking the steering and front axle bearings, since compact, manoeuvrable tractors of this class often worked in tight terrain with frequent steering movements. The lift cylinder seals in the hydraulics and the four-wheel-drive hubs are also worth a look, along with any cab corrosion on machines that stood outdoors for long periods.
