Porsche Diesel AP
3 models in this series
Porsche Diesel AP range – early Allgaier-Porsche tractors AP16 to AP22S from Friedrichshafen, 12 to 16 kW, two-cylinder engines of 1,374 to 1,531 cm³, 16 to 22 hp
The AP range stands at the beginning of the Porsche Diesel story: it grew out of the cooperation between Allgaier and Porsche in Friedrichshafen on Lake Constance, before Porsche took over the tractor business fully in 1956; the AP code refers to this Allgaier-Porsche phase of the 1950s. The type numbers 16, 17 and 22 directly denote the power in hp, and the S suffix on the AP22S an uprated version.

The register lists here 3 versions with 11.8 to 16.1 kW, or 16 to 22 hp, from two-cylinder engines of 1,374 to 1,531 cm³, unladen weights from 1,017 to 1,115 kg, lengths from 2,550 to 2,640 mm, widths from 1,052 to 1,530 mm, heights from 1,420 to 1,495 mm and a rated speed of 2,000 rpm.
At around 16 to 22 hp, the AP range belonged to the lower class of West German post-war tractors and competed with comparable small tractors from Fendt, Eicher and Hanomag; it served mainly smaller farms during the early mechanisation of agriculture.
On a used AP tractor, the condition and tightness of the air-cooled two-cylinder diesel engine, rust on the sheet-metal panels and wings, the condition of the steering and brakes, and the completeness of fittings such as the PTO and belt pulley all count, as these are often missing or were retrofitted on these early models. It is also worth checking the originality of the type plate, since engines swapped from other models in the range do occur on tractors of this class.
