The compact mowing machine according to the present invention also has a non-productive and cut basis of double cutting which allows the crop cut at the front part of the cutting blade holding plate 6 to be cut back at the back part as the cutting operation continues. The lower blade 10 is provided at the lower portion of the cutting blade 7 and the cutting blade fixing plate 6 which rotate to prevent the cutting blade fixing plate 6 from being reduced by the rotational force.

In addition, the mowing machine of the present invention, when the front wheel 35, the rotating drum 24 and the cutting blade fixed plate 6, etc. are momentarily interrupted while the rotation is stopped, the reducer 12 and other during rotational movement In order to prevent the vulnerable part of the body from being damaged, the clutch 14 can be idling when severe overload is applied, and the clutch 14 is idling beyond the contact angle when the grab handle 34 is pushed and pulled more quickly. It is possible to rotate the rotary drum 24 which is interlocked with the front wheel 35 more quickly to have a direction change device 20 that can increase the amount of work by the discharge of the cutting material and the progress of the harvester faster.

The compact mower of the present invention thus constructed is operated as follows.

The compact mowing machine of the present invention can easily start the prime mover 2 when the operator pulls the start knob 1 of the prime mover, and the centrifugal force clutch 3 is driven by the centrifugal force when the prime mover 2 rotates normally after starting. It operates automatically to rotate the prime mover shaft (4). When the cutting blade rotating shaft 5, which is powered by the pulley and the belt fixed to the prime mover shaft 4, rotates, the cutting blade fixing plate 6 fixed to the lower end of the cutting blade rotating shaft 5 rotates at the same speed. do. The cutting blades 7 and the upper blades 8 bolted to the edges of the cutting blade holding plate 6 in a rotational direction and horizontally bolted together with the cutting blade holding plate 6 at the same speed as the prime mover 2 (2,000). To 6,000 RPM), the crop to be cut that touches the cutting blade 7 is easily cut by power without borrowing human power.

On the other hand, the rotational power of the prime mover is transmitted to the reducer shaft 11 by a pulley and a belt separately fixed to the prime mover shaft 4, and the rotational force of the low speed (20 to 69 RPM) decelerated in the reducer 12 has an upper reduction shaft.
