The Brockenhexe utilises a frameless block construction, a dead front beam axle and a rear live axle. Due to the lack of a small DDR-made diesel engine, the Deutz licensed F2M 414 engine was used. The straight two-cylinder, four-stroke diesel engine with water-cooling and prechamer injection, produces 16,2 kW at 1500 min⁻¹; the displacement is 2200 cm³. The engine has a decompression system and a hand crank for starting. The torque is transmitted to the gearbox with a clutch of the type Renak 16K. The gearbox was also built under licence. It is a ZF Friedrichshafen four-speed gearbox with a reverse gear. For braking, drum brakes are used, whereas the hand brake is a gearbox brake. For power take-off, the tractor has a belt-pulley and an engine speed dependent PTO. Some Brockenhexe units were equipped with a cab, some tractors also have a mower bar.
