Aebi AM

The type number rises with size and output. In the register the models run from 3.3 to 10.3 kW (7 to 14 hp), 212 to 550 cm³ with one or two cylinders and weights from 110 to 320 kg; 15 of the 18 models with a fuel entry run on petrol, three optionally on diesel. The engines came from suppliers such as MAG, Hirth, Bernard and later Kubota and Lombardini.

The motor mower is a tool carrier: cutter bar for mowing, belt rake, hay pusher, snow blower, plough, load platform and trailer hitch swap on the same PTO. Aebi's 'Hang' (slope) suffix meant differential lock, cage wheels and a low centre of gravity for inclines up to 40 degrees.

Used old AMs are common and cheap, good examples with attachments sought after. When buying, engine condition (compression, ignition on magneto types), gearbox and clutch, the mower with knife and fingers and the cage or lug wheels are what count.
