Abstract

In a lawn mower for mowing lawns on a ground having a drive shaft adapted to transmit a rotational driving force of a operating motor (prime mover), three blades and a connecting member having a blade disk adapted to connect the blades with the drive shaft, a fan is integrally formed at the connecting member. The blades are attached to the connecting member at a circumference of the connecting member and to be movable relative to the connecting member in a radial direction of the connecting member.

Claims

1. A lawn mower for mowing lawns on a ground having a drive shaft adapted to transmit a rotational driving force of a prime mover, a blade and a connecting member adapted to connect the blade with the drive shaft,

wherein the improvement comprises:

a fan is integrally formed at the connecting member.

2. The lawn mower according to claim 1, wherein the connecting member has a disk-like shape and the blade comprises a plurality of the blades that are attached at a circumference of the connecting member.

3. The lawn mower according to claim 1, wherein the blade has a substantially rectangular shape.

4. The lawn mower according to claim 3, wherein the blade is attached to the connecting member to be able to swing relative to the connecting member.

5. The lawn mower according to claim 1, wherein the blade has a substantially disk-like shape.

6. The lawn mower according to claim 5, wherein the connecting member has a disk-like shape and the blade is attached to the connecting member to be movable relative to the connecting member in a radial direction of the connecting member.

7. The lawn mower according to claim 1, wherein the drive shaft, blade and connecting member are mounted on an operating vehicle body adapted to be controlled to run about in an operating area to perform an operation using the blade.
