摘要： A lawn mower comprising a cutting unit disposed between front and rear wheels, a grass discharge duct extending rearwardly from the cutting unit, and a grass collecting container defining a top opening for receiving grass clippings sent through the discharge duct. The grass collecting container includes a mouthpiece extending along peripheries of the top opening to rest on a U-shaped support frame mounted at a rear end of the mower. The mouthpiece is connected to the support frame by a projection and bore engagement. The support frame includes a holder defining an upwardly opening recess, and the container has a cover defining a downwardly opening recess at a position opposed to the holder. The two recesses define an opening for receiving a rear end of the grass discharge duct. The grass discharge duct includes an annular engagement portion extending peripherally of the rear end thereof for engagement with inner edges of the two recesses.

摘要： A cooling system for a vertical, liquid cooled engine having a first passage for guiding cooling air to a cooling fan disposed above the engine, and a second passage for guiding the cooling air drawn by the cooling fan to flow past the engine and to be exhausted forwardly and downwardly of the engine. The first passage includes an air inlet defined rearwardly of the engine, and is defined by part of an engine hood, a vertical bracket plate erected behind the engine, and a partition extending from the engine hood over an upper surface of the engine. Devices accessory to the engine which are vulnerable to the heat are mounted in a space inside the first passage. The second passage is formed by an air guide cover enveloping the engine and cooling fan and defining an opening in a region opposed to the cooling fan. The air guide cover includes a front portion extending downwardly along the cylinder head. The second passage contains a liquid cooler disposed between an upper surface of the cylinder head and the air guide cover, and a muffler in an exhaust region the second passage. The first and second passages are interconnected through the cooling fan, and define a substantially airtight space from air intake end to exhaust end.

摘要： A mower unit of grass cutting machine has at least two blades. The left blade is rotatable clockwise, while the right blade is rotatable counterclockwise. A grass discharge passage is formed between the two blades. An endless rotational belt for transmitting drive to the two blades is offset forwardly in a region between the blades, thereby forming, between the blades, a space without the endless rotational belt. The grass discharge passage has an upper surface inclined rearwardly and upwardly to extend from a position forwardly of a pair of pulleys corresponding to the two blades.

摘要： A work vehicle includes: a muffler which flows exhaust from an engine and extends in a transverse direction so as to allow the exhaust from the engine to flow in the transverse direction; and a CVT case for covering a belt-type CVT positioned frontward of the muffler in a longitudinal direction. The CVT case includes a cooling structure for introducing cooling air from outside, cooling the belt-type CVT, and discharging the cooling air from a discharge part. An exhaust duct includes an inflow opening to be connected to the discharge part for allowing the cooling air to flow into the exhaust duct, and an exhaust opening for allowing the cooling air to flow out rearward. The exhaust opening is elongated in an extending direction of the muffler and oriented in a direction that allows the cooling air flowing out to hit the muffler.
