Güldner AX, AK, AB, ABL, A3P

The Güldner AX and AK models introduced in 1956 were the first to feature Güldner’s new design with an oval-shaped grille. The new air-cooled models were developed in cooperation with Fahr. The 1-cylinder 11-horsepower AX corresponded to the Fahr D 66, and the 2-cylinder 13-horsepower AK matched the D 88. The ZF transmission had two ranges, with a crawler gear as an option. There were 6+2 (9+3) gears. Both models were available in green and blue. The AK was one of Güldner’s most produced models.

In 1958, the 25-horsepower AB received a new design, replacing the previous ABS. The most significant technical change was a roller-bearing crankshaft. The wheelbase was extended by 10 centimeters. The same tractor was also offered as an air-cooled version under the name ABL. These models were the first Güldners to offer red as a color option.

In 1957, Güldner introduced its first three-cylinder model, the A3P. It was also the first model to use a purchased engine, a 2.36-liter Perkins. Power was 32 hp. The ZF transmission had only 5+1 gears, with crawler gears 8+2.
