Patent number: 4903469Abstract: 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.Type: GrantFiled: October 16, 1987Date of Patent: February 27, 1990Assignee: Kubota, Ltd.Inventors: Masatake Murakawa, Niro Bando, Masatsugu Tone, Mikio Yuki, Junji Miyata, Tetsuaki Hayashi, Kazuaki Kurohara

Patent number: 4756208Abstract: A mid-mount lawn tractor comprising an engine, front and rear wheels, and a working implement or lawn mower mounted between the front and rear wheels. A transmission is disposed adjacent the rear wheels and includes an upwardly extending input section. The transmission is housed in a transmission case defining an opening at an upper portion thereof for exposing the input section. A hydraulic stepless change speed apparatus is disposed above the transmission. The change speed apparatus includes a downwardly extending input shaft for receiving power of the engine through an endless belt, and a downwardly extending output shaft connected through the opening of the transmission case to the input section of the transmission.Type: GrantFiled: January 5, 1987Date of Patent: July 12, 1988Assignee: Kubota, Ltd.Inventors: Tetsuaki Hayashi, Hiroyuki Ogasawara, Nobuyuki Yamashita, Niro Bando
