The Aebi HC 55 is a single-axle tractor manufactured from 1995 to 2005. This machine belongs to the HC series by the Swiss manufacturer Aebi and is specifically designed for use in mountain agriculture, where conventional four-wheel tractors often reach their limits due to steep slopes. As a single-axle vehicle, it is steered via a drawbar or a seat wagon, with power transmission occurring through two wheels. The design enables precise maneuvering even on difficult terrain and safe towing of attached implements.
The HC 55 is powered by an air-cooled two-cylinder gasoline engine with a displacement of 480 cm³. At a rated speed of 3,600 rpm, the engine delivers 12.5 hp (9.2 kW). This power output is sufficient to handle typical work on slopes without the machine excessively compacting the soil due to its weight. With an empty weight of 186 kg, the machine remains light enough to be used on sensitive soils or steep surfaces without sinking in deeply. The top speed of 10 km/h is designed for safe and controlled movement across the terrain.
Within the series, the HC 55 is positioned as the more powerful variant compared to the HC 44. While the HC 44 operates with a single-cylinder engine and 11 hp (8.1 kW), the HC 55 offers a higher power reserve due to its two-cylinder engine and larger displacement. This difference makes the HC 55 suitable for more demanding towing tasks or the operation of heavier attached implements, where the HC 44 may reach its performance limits. The higher speed of 10 km/h compared to the 6.8 km/h of the smaller model also allows for faster travel between work sites.
Aebi HC 44 – an air-cooled single-axle tractor for mountain farming: single-cylinder petrol engine of 400 cm³, 11 hp/8.1 kW, four-wheel drive and 210 kg weight, 1999–2007
Aebi of Burgdorf in Switzerland has for decades built single-axle tractors and transporters for mountain farming, where steep slopes make the use of conventional four-wheel tractors difficult. The HC 44 belongs to the brand's single-axle tractor range.

The HC 44 is powered by an air-cooled single-cylinder engine of 400 cm³ displacement, running on petrol, delivering 11 hp or 8.1 kW at a rated speed of 3,600 rpm. As a single-axle tractor with four-wheel drive, 21x11.0-8 tyres at the front and a weight of 210 kg, the machine reaches a design top speed of 6.8 km/h.
The single-axle tractor transmits its power through two wheels guided by the operator via a drawbar or a seated cart, making it more manoeuvrable and more resistant to tipping on slopes than a four-wheel tractor of the same power. Air cooling makes the engine independent of a water-cooling circuit, saving weight and simplifying use even at an angle; at 6.8 km/h the machine moves only at working pace.
When buying a used Aebi single-axle tractor, the condition of the steering and clutch mechanism at the drawbar and the fins of the air cooler matter, checked for dirt and damage. Tyres, drive chains or shafts, and the mounting of implements should be checked for wear caused by use on slopes, and the engine should be tested cold as well as warm.

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.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
