The abbreviation “S” denoted the standard version. AP/S no longer means Allgaier Porsche Standard, but Aluminum Porsche Standard. Compared to the Standard AP, the Porsche Standard AP/S has two more horsepower.

The tractor could work with the PTO shaft in all gears, except in creep gear. The front engine PTO could be switched on separately. The external mower drive in the Porsche standard assembly instructions could be driven directly by the engine via the V-belt pulley. All tractors were equipped with a Porsche three-point hitch for the hydraulic power lift.

The front axle was only sprung on the Porsche Traktor Standard AP/S on request. The front and rear portal axles were adjustable in track, which could be reinforced by wheel discs and wider rims.

 An all-weather hood was optional. The Porsche Standard AP/S could be retrofitted with rear lights, a fuel gauge and a fender seat.
