Mower and grass mowing machine including the same

1. A mower for discharging mowed grasses from a discharge port provided in a side part of a mower deck to an exterior of the mower deck, the mower comprising:

a flexible guide member formed in a flat plate shape;

a coupling assembly attaching the guide member to the mower deck for pivotal movement in an up and down direction in relation to the mower deck, the coupling assembly comprising a pivot frame fixed to the guide member and for movement with the guide member during said pivotal movement;

the guide member being configured to assume the flat plate shape while fixed to the mower deck via the coupling assembly; and

a fixing member for fixing the guide member to the mower deck in a state that the guide member is bent into a shape capable of guiding the mowed grasses discharged from the discharge port, the fixing member being separate from both the pivot frame and the guide member.

2. The mower according to claim 1 , further comprising:

a retaining member for retaining the guide member whose fixing by the fixing member is released in an oscillated upward state of the guide member.

3. A grass mowing machine comprising the mower according to claim 2 .

4. The mower according to claim 1 , wherein:

the flexible guide member is configured to be moved from an accommodation state to a working state;

in the accommodation state, the discharge port is in an open position, but the flexible guide member is not fixed in the bent state capable of guiding the mowed grasses discharged from the discharge port; and

in the working state, the discharge port is in an open position, and the flexible guide member is fixed in the bent state capable of guiding the mowed grasses discharged from the discharge port.

5. The mower according to claim 1 , wherein:

the flexible guide member is configured to be bent, while attached to the mower deck, from the flat plate shape to a working state; and

in the working state, the fixing member fixes the guide member in the bent state against an elastic biasing force of the guide member.

6. The mower according to claim 5 , wherein:

when the flexible guide member does not fix the guide member in the working state, the flexible guide member is elastically biased to the flat plate shape.

7. The mower according to claim 1 , wherein:

in the flat plate shape, the flexible guide member consists of only a single flat plate.

8. The mower according to claim 1 , wherein:

in addition to the fixing member, the mower includes a second fixing member;

the flexible guide member is configured to be bent, while attached to the mower deck, from the flat plate shape to a working state;

in the working state, the guide member has a substantially tubular shape having an upper side, a pair of spaced-apart opposite sides, and an open bottom; and

the fixing member fixes one of the opposite sides of the guide member to the mower deck and the second fixing member fixes a second of the opposite sides of the guide member to the mower deck.

9. The mower according to claim 2 , wherein:

in the oscillated-upward state of the guide member, the guide member is positioned away from the discharge port and the discharge port is open.

10. The mower according to claim 2 , wherein:

in the oscillated-upward state of the guide member, an entirety of the guide member had been oscillated upwardly.

11. The mower according to claim 2 , wherein:

in the oscillated-upward state of the guide member, the guide member is not fixed to the mower deck by means of any fixing member.

12. The mower according to claim 2 , wherein:

in the oscillated-upward state of the guide member, the retaining member retains the guide member in the oscillated-upward state and against returning to the flat plate shape.

13. A mower for discharging mowed grasses, said mower comprising:

a mower deck having a side part provided with a mowed-grasses discharge port provided to discharge the mowed grasses to an exterior of the mower deck;

an elastically deformable guide member configured to assume a non-biased flat shape;

a coupling assembly connecting the guide member to the mower deck to pivot in relation to the mower deck in an up and down direction during the movement between a working state and an accommodation state, the coupling assembly comprising a pivot frame fixed to the guide member for movement with the guide member during the movement between the working and accommodation states;

in the working state, the guide member being deformed into a substantially tubular shape having an upper side and two spaced-apart sides to guide the mowed grasses from the discharge port;

in the accommodation state, the guide member extends above the discharge port, thereby leaving the discharge port open;

at least one fixing member configured to fix the guide member to retain the guide member in the working state, the fixing member being separate from both the pivot frame and the guide member.

14. The mower according to claim 13 , further comprising:

at least one retaining member configured to retain the guide member in the accommodation state.

15. The mower according to claim 13 , wherein:

the fixing member is fixed to the mower deck.
