A work unit to be attached to a lower side of a work vehicle that includes a wheel includes a work portion, a housing that covers the work portion, a bridge portion that is provided above the housing, auxiliary plates that change their positions between a state of being housed in the bridge portion and a state of protruding from the bridge portion, a linkage mechanism that is provided in the bridge portion and is connected to the auxiliary plates, and an operation tool for operating the linkage mechanism. As a result of operating the operation tool, the linkage mechanism is folded or unfolded, and positions of the auxiliary plates are changed between the state of being housed in the bridge portion and the state of protruding from the bridge portion.

Work unit with an auxiliary plate

A work vehicle including: a vehicle body frame; a prime mover part located on a front or rear part of the vehicle body frame; a bonnet configured to open and close by swinging, and covering the prime mover part; and an assist unit configured to assist the bonnet to operate to open. A lateral end portion of the vehicle body frame is provided with a first linkage part with which the assist unit is linked. A lateral end portion of a lower end part of the bonnet, which is located closer to an end cover than the first linkage part is, is provided with a second linkage part with which the assist unit is linked. The assist unit is provided with an expansion/contraction mechanism biased so as to expand, and is located laterally outside the prime mover part and spans the first linkage part and the second linkage part.

Work vehicle

A work vehicle includes a vehicle body frame, a protection frame extending upwards from the vehicle body frame, the protection frame including left and right strut members and an arch member extending between and detachable from the left and right strut members, a support frame provided in the vehicle body frame and configured to support the protection frame to the vehicle body frame, the support frame including a pair of left and right pipe-like supporting portions, each supporting portion being provided under a laterally outward tilted orientation with an upper portion of the supporting member being positioned on more laterally outer side of a vehicle body and being configured to removably support the strut member, and a connection tool configured to non-removably connect the left and right strut members to the left and right supporting portions.

A mower unit is detachably mounted between front wheels and rear wheels of a mid-mount grass mower. The mower unit includes a blade cover having a top plate and a side plate extending from a circumferential edge of the top plate, a pair of right and left ride-over deck units provided on the top plate. Each ride-over deck unit includes a support deck fixed to an upper face of the top plate, a wheel guide member movable between a home position for storage in the support deck and a bridging position for bridging between the support deck and a ground surface, and a tethering member for tethering the support deck with the wheel guide member.

Mower unit

A mower unit includes a mower deck, a plurality of blades mounted inside the mower deck and rotatable about vertical shafts supported to the mower deck, the mower deck defining, on one lateral side thereof, a discharge outlet for discharging cut grass cut by the plurality of blades, and an opening and closing member configured to be movable to a closing position for closing the discharge outlet and also to an opening position away from the discharge outlet for opening the discharge outlet, the opening and closing member at the opening position being disposed along an outer face of the mower deck.

A riding type mower includes: a vehicle body, a driver's seat mounted on the vehicle body; an operation part arranged around the driver's seat; a mower unit provided on the vehicle body; a shutter for closing a discharge port; a shutter moving mechanism for moving the shutter between a close position closing the discharge port and an open position opening the discharge port; and a lock mechanism for locking the shutter at the close position. The mower unit includes: a mower deck; a cutting blade installed inside the mower deck; the discharge port formed in the mower deck, through which mown grass cut by the blade is discharge from the mower unit to outside. A shutter operating tool for remotely operating the shutter moving mechanism to open and close the shutter is provided in the operation part. The lock mechanism is remotely operable from the operation part.

Riding type mower

A grass collecting apparatus for a lawn mower comprises a frame () supported by a vehicle body, a container supporting member () for supporting a grass collecting container () for storing grass clippings and including a container supporting surface () for receiving an opening edge of the grass collecting container, and a container cover () mounted on the frame to be oscillatable about a horizontal axis between a closed position and an opened position. An engaging member () is mounted on the container cover (). The engaging member () is engageable with the opening edge () of the grass collecting container () with oscillation of the container cover () from the opened position to the closed position, thereby positioning and maintaining the grass collecting container () on the container supporting member (), and disengageable from the opening edge () of the grass collecting container () with oscillation of the container cover () from the closed position to the opened position.

Grass collecting apparatus for lawn mower

A mower includes a mower deck that opens downward; a plurality of vertical shafts rotatably supported by the mower deck; a plurality of cutting blades driven by the vertical shafts inside the mower deck; a cutting chamber formed inside the mower deck and provided for each cutting blade; and an opening formed between the cutting chambers for adjacent cutting blades. The cutting blades are arranged generally in a lateral direction with an adjacent pair of cutting blades being rotatably driven in opposite directions from each other. The opening allows for flow passage of cut grass at least from one of the cutting chambers to the other cutting chamber.

Mower having cutting chambers

A riding-type mower vehicle comprises a mower supported by a vehicle body; a grass collector configured to receive cut grass cut by the mower; a vehicle-side connector located at a rear position of the vehicle body and having a pair of inclined guide portions that face each other such that a distance between the inclined guide portions decreases toward lower portions of the inclined guide portions to open upwardly; and a collector-side connector provided to the grass collector to extend generally downwardly and having a pair of inclined guided portions whose distance from each other decreases toward lower portions of the inclined guided portions; wherein the collector-side connector is attached to the vehicle-side connector by inserting an inclined guided portion of the collector-side connector between the pair of inclined guide portions of the vehicle-side connector.
