Aebi TT (Terratrac) – Swiss slope transporter from Burgdorf: TT 80 to TT 281, four-cylinder diesels rated 36–80 kW, low centre of gravity for steep terrain
Aebi's TT line is the Terratrac family from the Swiss maker in Burgdorf, specialised in transport work and light draft work in mountain and slope terrain. Aebi was founded in 1883 and developed the Terratrac concept as vehicles with a low centre of gravity, four-wheel drive and a swivelling driver's seat for work on steep slopes; the TT type designation stands for Terratrac, with the following number marking the model step. From the TT 80 as the smallest to the TT 281 as the most powerful model, the line covers a wide power range for grassland, transport and municipal work.

The register lists 6 versions rated at 36 to 80 kW (49 to 109 hp) from four-cylinder diesel engines of 2,615 to 2,970 cm³, torque of 170 to 310 Nm at 2,600 to 2,700 rpm, kerb weights of 1,800 to 2,850 kg, and a length of 3,440 to 4,090 mm, a width of 1,880 to 2,110 mm and a height of 2,070 to 2,220 mm.
TT vehicles are mainly found in Switzerland, Austria and the mountain regions of southern Germany, where they work land too steep for conventional tractors; typical tasks are hay and grass harvesting, transport work and winter service with attachments. Competition comes chiefly from the Austrian makers Reform and Lindner.
On a used Terratrac, check the condition of the engine and drivetrain, the articulation bearing of the folding chassis, the hydraulic pump and cylinders, and the brakes and tyres; given slope use, it is worth carefully checking the frame and implement mounts for cracking. Aebi supplies spares through its own dealer network in Switzerland and Austria.

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.
