Patent number: 6971469Abstract: A self-propelled working vehicle comprises a front wheel unit, a rear wheel unit including a left rear wheel and a right rear wheel, and a drive transmission apparatus for transmitting drive from an engine to the rear wheel unit. The drive transmission apparatus includes a first drive transmission mechanism for transmitting the drive to the left rear wheel and a second drive transmission mechanism for transmitting the drive to the right rear wheel. The first transmission mechanism is arranged at the left side of the vehicle body, while the second transmission mechanism is arranged at the right side of the vehicle body. A brake assembly is arranged between the first drive transmission mechanism and the second drive transmission mechanism for acting on an output shaft of a first transmission unit and an output shaft of a second transmission unit. The first and second transmission units act as first and second change speed devices, respectively, which are operable independently of each other.Type: GrantFiled: February 28, 2003Date of Patent: December 6, 2005Assignee: Kubota CorporationInventors: Hideya Umemoto, Takeshi Komorida, Shoso Ishimori, Takashi Fujii, Koji Fujiwara, Hiroyuki Tada

Patent number: 6931827Abstract: A grass collecting apparatus for directing grass clippings cut by a mower unit to a grass catcher. The apparatus includes a grass collecting duct for guiding the grass clippings from the mower unit to the grass catcher, the duct having an outlet portion leading to the grass catcher defined by an upper plate, right and left side plates and a bottom plate, a gate-shaped frame disposed in a boundary between the outlet portion of the grass collecting duct and an opening of the grass catcher, and a swing mechanism for swinging the grass catcher between a grass collecting position and a grass discharging position. The bottom plate is arranged to receive the grass clippings falling off an area when the grass catcher is in the grass collecting position, and is displaced with a surface being tilted when the grass catcher is swung from the grass collecting position to the grass discharging position.Type: GrantFiled: August 21, 2003Date of Patent: August 23, 2005Assignee: Kubota CorporationInventors: Takeshi Komorida, Nobuyuki Yamashita, Shoso Ishimori

Patent number: 6672043Abstract: A lawn mower for directing grass clippings to a grass catcher. The lawn mower includes a vehicle body and a mower unit supported by the vehicle body to be vertically movable for varying a height thereof above the ground. The mower unit includes a housing, cutting blades rotatable about vertical shafts, and a grass clippings discharge channel connected to the housing and opening downward for rearwardly directing grass clippings cut by the cutting blades. The lawn mower further includes a grass collecting duct for connecting a discharge opening of the grass clippings discharge channel to the grass catcher, and a receiving plate having a receiving surface for covering the downward opening of the grass clippings discharge channel.Type: GrantFiled: August 26, 2002Date of Patent: January 6, 2004Assignee: Kubota CorporationInventors: Takashi Shibata, Takashi Fujii, Hideya Umemoto, Takeshi Komorida, Hiroyuki Tada, Nobuyuki Yamashita, Shoso Ishimori

Patent number: 6588299Abstract: A transmission for a working vehicle comprising a transmission mechanism for controlling drive transmission; a first input shaft for transmitting drive from an engine to the transmission mechanism; a second input shaft, usable as an alternative to the first input shaft, for transmitting drive from the engine to the transmission mechanism, the second input shaft extending in a different direction to the first input shaft; an implement-operating output shaft for outputting drive from the transmission mechanism to drive a working implement; and a pair of right and left propelling output shafts for transmitting drive from the transmission mechanism to drive wheels, the propelling output shafts extending in the same direction as axes of the drive wheels. The first and second input shafts extend transversely of the propelling output shafts. The implement-operating output shaft extends in the same direction as the first input shaft.Type: GrantFiled: August 8, 2001Date of Patent: July 8, 2003Assignee: Kubota CorporationInventors: Shoso Ishimori, Takeshi Komorida, Nobuyuki Yamashita
