Abstract
A mowing machine for cutting plants with radially protruding blades of upper and lower blade disks which are coaxially disposed and rotated under the hood that is disposed at the end of a handle. The upper blade disk has a ring gear, the lower blade disk has a sun gear, and a transmission gear is provided between the ring gear and the sun gear and meshes these gears so as to rotate the ring and sun gears in the opposite directions, thus rotating the upper and lower blade disks in the opposite directions for producing a shearing force that cuts the plants.

A mowing machine for cutting plants using a plurality of blades protruding from edges of an upper blade disk and a lower blade disk, which are coaxially disposed and rotate in opposite directions, characterized in that the mowing machine comprises:
- a plate-shaped main unit case provided with vertical supporting bars disposed along a circle having a specific radial distance from a center of the main unit case;
- a sun gear equipped with a lower blade disk and a ring gear equipped with an upper blade disk, said sun gear and ring gears being provided below the main unit case and coaxial with said circle;
- rotary elements that are provided between and circumscribe the sun gear and inscribe the ring gear and are rotatably mounted on at least a plurality of the vertical supporting bars, at least one of said rotary elements being a transmission gear meshing with both the sun gear and the ring gear, and said at least one transmission gear being a driving gear driven by a power source;
- and
- a holding means provided on each of said supporting bars for preventing radial play of the transmission, sun and ring gears.
