Bungartz – other models: Munich tool carriers outside the named ranges, from the F40 and F55 to the H1, H2, H5, K5, L3, L4 and RM 158, 5 to 6 hp, air-cooled single-cylinder engines
This page gathers the Bungartz tool carriers the register could not assign to a named range: F40, F55, F70, F90, FR, FRN, H1, H2, H5, K5, L3, L4, RM 158 and RM 158 Z. Bungartz was a Munich maker of tool carriers, small self-propelled vehicles for interchangeable implements in agriculture, horticulture and municipal service. The short type codes of a letter and a number distinguish different sizes and equipment levels within the range.

The register lists here 14 versions; the engines produce 5 to 6 hp, around 4.4 kW, with 199 to 277 cc displacement and one cylinder, run on petrol or a petrol-oil mix at a ratio of 1:25, and turn at 3,000 rpm. The tool carriers weigh 135 to 150 kg, and measure 1,600 mm in length, 420 mm in width and 900 mm in height.
As small, light tool carriers with mixture lubrication, the Bungartz models were built chiefly for work with implements such as a mower bar, tiller or small trailer on tight plots, where larger tractors would have been too heavy or unwieldy.
When buying used, check on these two-stroke tool carriers the condition of the piston and cylinder, correct mixture lubrication, the condition of the clutch and belt drive, the frame and implement mounts, and corrosion on sheet metal and frame parts; spares for the now-discontinued brand are mainly found through collector and vintage-machinery markets.

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.
- 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.
