The 983 has a six-cylinder Caterpillar D343 engine fitted with a Turbocharger, producing 275 hp (205 kW) (FWHP). It has a three-speed powershift transmission. It comes standard with oil cooled brakes and clutches, pedal steer, electric start, hydraulic track adjusters, and a 22-inch (56-cm) double Grouser Shoes track.
