Abstract

Disclosed is a mower unit including, on a mower deck that rotatably supports a blade, a deck-side electric component configured to drive the blade, and a joint section for effecting connection and disconnection of a harness that electrically connects the deck-side electric component to a vehicle body-side electric component.

Claims (33)

1. A mower unit comprising:

a blade configured to be rotatably driven to cut grass on a ground surface;

a mower deck that rotatably supports the blade;

a deck-side electric component associated with the mower deck and configured to drive the blade; and

a joint section provided on the mower deck for effecting connection and disconnection of a harness that electrically connects the deck-side electric component to a vehicle body-side electric component associated with a vehicle body,

wherein the joint section comprises an elongated element having a deck-side connector at one longitudinal end thereof and a vehicle body-side connector at the other longitudinal end thereof, the connection and disconnection of the harness associated with the deck-side electric component being effected at the deck-side connector, and the connection and disconnection of the harness associated with the vehicle body-side electric component being effected at the vehicle body-side connector.

2. The mower unit of claim 1 , wherein:

the mower deck includes a housing that covers the blade; and

the joint section is supported on the housing.

3. The mower unit of claim 1 , wherein the joint section is provided with dust/water proof arrangement.

4. The mower unit of claim 1 , wherein:

the deck-side electric component comprises an electric motor that rotatably drives the blade; and

the vehicle body-side electric component comprises an inverter configured to vary a rotational speed of the electric motor.

5. The mower unit of claim 1 , wherein:

the deck-side electric component comprises an inverter configured to vary a rotational speed of an electric motor that rotatably drives the blade; and

the vehicle body-side electric component comprises a battery that supplies electric power to the inverter.

6. A riding type grass mower vehicle including a vehicle body and a mower unit mounted on the vehicle body,

wherein the mower unit comprises:

a blade configured to be rotatably driven to cut grass on a ground surface;

a mower deck that rotatably supports the blade;

a deck-side electric component associated with the mower deck and configured to drive the blade; and

a joint section provided on the mower deck for effecting connection and disconnection of a harness that electrically connects the deck-side electric component to a vehicle body-side electric component associated with a vehicle body,

wherein the joint section comprises an elongated element having a deck-side connector at one longitudinal end thereof and a vehicle body-side connector at the other longitudinal end thereof, the connection and disconnection of the harness associated with the deck-side electric component being effected at the deck-side connector, and the connection and disconnection of the harness associated with the vehicle body-side electric component being effected at the vehicle body-side connector.

7. The riding type grass mower vehicle of claim 6 , wherein:

the mower deck includes a housing that covers the blade; and

the joint section is supported on the housing.

8. The riding type grass mower vehicle of claim 6 , wherein the joint section is provided with dust/water proof arrangement.

9. The riding type grass mower vehicle of claim 6 , wherein:

the deck-side electric component comprises an electric motor that rotatably drives the blade; and

the vehicle body-side electric component comprises an inverter configured to vary a rotational speed of the electric motor.

10. The riding type grass mower vehicle of claim 6 , wherein:

the deck-side electric component comprises an inverter configured to vary a rotational speed of an electric motor that rotatably drives the blade; and
