History of the Deutz F1L 514/51
The type designation
The type designation of the F1L 514/51 gives the main engine data: a vehicle engine with one cylinder and air cooling of the 5 series, with a piston stroke of 14 cm. Behind the slash stands the actual model number. The tractor was developed from the F1L 514/50 and, like its predecessor, had an air-cooled single-cylinder diesel engine producing 15 hp (11 kW).

What was new
Compared with the earlier model, the F1L 514/51 was fitted with a better stepped five-speed gearbox with a differential lock, and it reached a top speed of 23 km/h or 20 km/h depending on the gearbox version. The wheelbase was enlarged, and hydraulic lifts from Bosch and ATE were available as an option. Standard equipment included a belt pulley, an electric starter and a power take-off.
Equipment and versions
Further accessories such as a mower or an auxiliary gearbox with a creep speed could be ordered from the factory. The tractor could also be ordered as a plantation version with an external width of 1200 mm. In total 28,848 tractors of the F1L 514/51 type were built between 1951 and 1956, when the model was renamed the F1L 514/1.
