Hako HAKOrette: air-cooled single-cylinder two-stroke, 98 cc, 4 or 6 hp, belt pulley or Variomatic and a weight of only 65 kg, built in 1956
Hako Hans Koch & Sohn was the earlier company name of the manufacturer known today as Hako, based in Bad Oldesloe in Schleswig-Holstein. The HAKOrette was built in 1956 and was even smaller and lighter than the later HAKOrecord series.

The HAKOrette is powered by an air-cooled single-cylinder engine of just 98 cc, producing 4 or 6 hp, depending on the version, at 4,500 rpm, with engine speed limited to around 5,000 rpm. The engine runs on a two-stroke fuel mix of 1:25 and drives through a belt pulley or a Variomatic adjustment; gear changes go through a toothed gearbox with a roller chain running in an oil bath. At a weight of just 65 kg, a length of 1,500 mm, a height of 1,030 mm and a width of 720 mm, the HAKOrette is one of the lightest machines in the register.
A single-cylinder two-stroke of barely 100 cc and a weight of only 65 kg place the HAKOrette in the class of the simplest motorised garden helpers, built for domestic gardens or light work in tree nurseries rather than proper agricultural field use. The gearbox's roller chain, running in an oil bath, protects the drive components from dirt-related wear, which matters on such a lightly built machine.
When buying a HAKOrette secondhand, the condition of the belt pulley or Variomatic adjustment, and the level and tightness of the roller chain's oil bath, matter most. Also worth checking are the cooling fins of the air-cooled engine and the carburettor setting for the two-stroke mix; spare parts for such an old, small and rare machine can now practically only be found through specialist collectors.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Check the weights in the papers against the figures here — attachments change them.
- Check front and rear tyre sizes: mismatched pairs strain the drivetrain.
- Shift the gearbox cold and warm — jumps only show up at temperature.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
