Bucher Guyer B 1500: Swiss compact tractor of the B range, four-cylinder petrol engine with 18.4 kW (25 hp), 1,193 kg unladen weight, built 1955 to 1974
Bucher Guyer, a Swiss agricultural-machinery maker based in Niederweningen in the canton of Zurich, built small tractors for the country's farms alongside its farm equipment, competing with brands such as Hürlimann and Meili. The B 1500 was built from 1955 to 1974.

The B 1500 carries a water-cooled four-cylinder petrol engine of 1,488 cm³ displacement, producing 18.4 kW (25 hp) at 2,000 rpm and developing 96 Nm of torque – an engine of the light class typical of smaller Swiss farms. With an unladen weight of 1,193 kg, a wheelbase of 1,650 mm, a length of 2,510 mm, a width of 1,520 mm and a height of 1,400 mm, it reaches a top speed of 20 km/h.
At 20 km/h the B 1500 falls within today's driving licence category L up to 40 km/h. The petrol engine was still common in smaller tractors of this power class at the time, before diesel engines took over the light class too in the following decades; water cooling allowed steadier full-load running than air-cooled designs of the period.
When buying a carburettor engine of this age second-hand, the ignition system and carburettor, the condition of the cooling system and water pump, and rust on the radiator and sheet-metal parts matter most. Spare parts for a small tractor of this Swiss marque are today only obtainable through specialist collectors and vintage-vehicle clubs.

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.
