Abstract

An electric work vehicle includes: a battery accommodating portion that is provided in the vehicle body and accommodates a battery; a first connector provided on the battery accommodating portion; a second connector provided on the battery; and an operating tool for moving the battery and the second connector, and switching from a pre-attachment orientation in which the second connector opposes the first connector to an attachment orientation in which the second connector is joined to the first connector.

Claims (19)

1. A mower unit comprising:

a blade that rotates around a rotation axis to mow grass on a ground surface;

a housing that covers the blade, a lower face of the housing being open; and

a cleaning mechanism that rotates around the rotation axis to remove foreign matter that is present in an internal space of the housing,

wherein the cleaning mechanism is configured to be switched between a withdrawal state in which the cleaning mechanism is not located on a rotation trajectory of the blade, and a use state in which the cleaning mechanism is located on the rotation trajectory of the blade and rotates together with the blade.

2. The mower unit according to claim 1 , wherein:

the cleaning mechanism includes a sliding portion configured to slide in a radial direction relative to the rotation axis, and

the cleaning mechanism is configured to be switched between the withdrawal state and the use state by sliding the sliding portion.

3. The mower unit according to claim 1 , wherein:

the housing includes a protruding portion that protrudes outward in the radial direction relative to the rotation axis, and

the protruding portion allows a part of the cleaning mechanism to enter the protruding portion to cause the cleaning mechanism to be switched to the withdrawal state.

4. The mower unit according to claim 1 , wherein the cleaning mechanism includes an exposed portion that is exposed outward of the housing when the cleaning mechanism is in the use state.

5. The mower unit according to claim 1 , further comprising:

a lock portion that is configured to lock the cleaning mechanism in the withdrawal state.

6. The mower unit according to claim 1 , further comprising:

a detection sensor that is configured to detect the withdrawal state or the use state of the cleaning mechanism.

7. The mower unit according to claim 6 , further comprising:

an electric motor that is configured to drive the blade, and

wherein, when the use state of the cleaning mechanism is detected by the detection sensor, the electric motor is controlled to reduce a driving speed thereof compared with when the withdrawal state is detected by the detection sensor.
