The KT 731 carries the same four-cylinder diesel engine with 8,590 cm³ of displacement as the range, producing 63 hp, or 46.34 kW, at 1,150 rpm, and working with circulation cooling. At 3,985 mm long, with a 2,250 mm wheelbase and 1,700 mm width and 2,280 mm height, the machine reaches a top speed of 9.5 km/h. At 1,150 rpm the engine ran markedly slower than later tractor diesels, which served durability.
As the version intended for series production, the KT 731 differed from the test build mainly in manufacturing detail, while the engine, drivetrain and dimensions of the design stayed the same. The circulation cooling and low top speed of 9.5 km/h again point to a purely field-work machine with no road approval in today's sense.
With such a rare series build, documenting provenance and the works number is especially important, to tell the vehicle apart from reproductions or museum reconstructions of the same design. Technically, the condition of the circulation cooling, the tightness of the fuel system and cracking of the engine block after decades of standing should be checked.
