The SX 1200 is powered by a six-cylinder engine of 6,000 cc with oil-and-water cooling, producing 88.3 kW (120 hp) at 2,350 rpm. At a weight of 6,100 kg, a wheelbase of 2,750 mm and a width of 2,450 mm, the tractor reaches a design top speed of 40 km/h. Height stands at 2,880 mm and length at 4,320 mm. The engine runs on diesel.
A six-cylinder of six litres marks a heavy field tractor, the kind used for tillage and drawbar work demanding high pulling force on larger farms. The oil-and-water cooling combines an oil cooler with the water-fed cooling circuit. The 40 km/h top speed requires the German T driving licence category, the power take-off runs at the standard 540 or 1,000 rpm, and the three-point hitch follows ISO 730, typically carrying category 2 implements at this weight.
Buying a used six-cylinder this heavy, the cooling system with its oil cooler and hydraulic tightness deserve particular attention. Also worth checking at inspection are the sheet metal for rust damage, the condition of the PTO bearings and weighing recorded hours against overall condition.
