Fortschritt ZT 320 is a series of agricultural tractors made by the East German manufacturer VEB Traktorenwerk Schönebeck.

The main parts that were supposed to receive an upgrade were, amongst other things, the three-point linkage, powertrain, driver's cab, and to fulfill contemporary regulations, the braking system.

Like any mid 20th century standard tractor, the ZT 320 series has an unsprung, rear beam axle that is directly flange-mounted to the gearbox.

The rear axle is also directly connected to an additional ladder frame without any spring elements or shock absorbers in between.

[1] This ladder frame, the so-called half-frame, offers high torsional stiffness,[3] and supports the engine as well as the driver's cab.

The 4 VD 14,5/12-1 SRW is a naturally aspirated, straight-four, water-cooled, diesel engine, that features MAN M-System wall-guided direct injection.

The interior is designed ergonomically, with an air-sprung driver's seat, well-placed levers and switches, and an adjustable steering column.
