A mower unit includes a housing, a pair of cutting blades arranged inside the housing, each of the cutting blades being rotatable about a respective vertical axis supported by the housing, the cutting blades being driven to be rotated in opposite directions, and a baffle arranged generally between rotation regions of the cutting blades to guide air flows generated by the cutting blades. The baffle defines an upper baffle portion located adjacent an upper region of the housing, a lower baffle portion located adjacent a lower region of the housing, and an air passage formed for allowing the air flows to flow between the upper baffle portion and lower baffle portion.

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 work vehicle comprises: a plurality of wheels; a vehicle body supported by the wheels; a transmission case provided on the vehicle body, the transmission case having a first case portion and a second case portion and a middle portion extending between respective lower portions of the first and second case portions, the transmission case being divided by an abutting surface extending in a vertical direction of the vehicle; a hydraulic device associated with the transmission case; a hydraulic pump supplying a hydraulic fluid to the hydraulic device; an oil path formed in a surface of the abutting surface, one end of the oil path being formed in the first case portion as an oil port for the hydraulic device, and the other end of the oil path opening to the second case portion; and a hydraulic fluid outlet provided to the first case and connected to the hydraulic pump to supply hydraulic fluid to the hydraulic pump.
