    摘要: A self-propelled work apparatus, especially a lawnmower, includes a chassis, at least one tool and a drive motor for driving the tool. The tool is height-adjustable with respect to the chassis. A setting unit is provided to set the relative position of the tool with respect to the chassis. The setting unit includes an actuating motor and a setting gear. The setting gear rotates by less than one full revolution between a first, lower end position of the tool and a second, upper end position of the tool. A detection device is provided to detect the height position of the tool. The detection device includes encoding elements on the setting gear and at least one detector. The at least one first encoding element for the first end position differs from the at least one second encoding element for the second end position.
