The invention concerns a steerable lawn mower. Its frame is divided into two parts turnable with respect to each other, a machine frame part (1<1>) with a first pair of wheels (2) connected to it, a motor (4) and a mowing device (5) being mounted on the machine frame part, and a steering frame part (1<2>) turnably connected to the machine frame part, with a second pair of wheels (3) mounted on the steering frame part. The lawn mower comprises an angle lever (7) for turnable connection of the machine frame part (1<1>) and the steering frame part (1<2>) to each other, which angle lever is mounted on the machine frame part (1<1>) with a bearing allowing it to turn about a first rotation axis (8) disposed at a first angle ( alpha ) oblique to the horizontal plane, and which angle lever is mounted on the steering frame part with a bearing allowing it to turn about a second rotation axis (9) disposed at a second angle ( beta ) oblique to the horizontal plane, the first rotation axis (8) and the second rotation axis (9) lying in the same plane, with a third angle ( gamma ) opening upward between them. The steering arm (6) is so connected to the angle lever (7) that, by turning the angle lever by means of the steering arm, the steering frame part is turned with respect to the machine frame part to steer the lawn mower. |
