And reduction are configuration is shown in Figure so that.

Reference numeral (72) denotes an anti-friction collar fitted to the assist spring mounting portion of the pivot shaft (65).

This embodiment is constructed as described above, and the cutting and feed chain clutches (36) (63) are operated manually by the cutting clutch lever (39) and automatically operated by the automatic motor (41). ), The clutch lever (3
When turning 9) on and off, the motor (41) is rotated integrally with the mounting plate (43) about the fulcrum shaft (42) to pull or loosen the wires (46) and (64). The clutches (36) and (63) are turned on and off.

On the other hand, when the clutch (36) (63) is turned on and off by driving the motor (41), the motor (41) and the mounting plate (43) are moved to substantially fixed positions (clutch lever (43)). 39) The clutch (36) (63) is turned on and off only by driving the motor (41) with the wires (46) and (64) acting, and the cutting height is constant. At this point, the clutches (36) and (63) are automatically disengaged. When the clutches (36) and (63) are disengaged and engaged by the motor (41), the assist spring (71) works to reduce the driving load of the motor (41), and when the clutch (36) (63) is engaged and disengaged. The motor (41) is provided with an overrun prevention moment due to the offset of the chain clutch wire (64) and the assist spring (71), thereby reliably preventing overrun of the motor (41).
Can be made smaller and lighter.

A spring hook for pivotally supporting the assist spring (71) toward the rotating body (44) is provided on the rotating body (4).
In 4), a pivot shaft (65) serving as a support shaft for supporting the clutch plate (66) is also used, thereby simplifying the structure and reducing the weight and size.

Further, each clutch wire (46) (6)
The pulling direction of the pulling force of 4) is made coincident with the cutting direction of the clutches (36) and (63) of the rotating body (44), and the pulling force of the wires (46) and (64) is applied to the cutting side of the motor (41). Since it is always operated, it is possible to maintain stability on the cut side and improve safety.

FIG. 10 shows another modification of the coupling structure of the clutch wire. As shown by the solid line in FIG. 10, only the reaping clutch wire (46A) is connected to the motor shaft when the clutches (36) and (63) are engaged. The wire (46A) is provided in a state of being pulled at an opposing position centered on (41a) to increase the tension of the wire (46A). Only the clutch wire (64A) is provided in a state of being pulled at a position facing the motor shaft (41a), and the tension of the wire (64A) is increased to reduce the driving load of the motor (41). This enables further reduction in size and weight.
