    Abstract: A lawn mower having a drive mechanism for the wheels of the mower, which mechanism includes a drive shaft and drive cog wheels for engagement with the ground wheels, the drive shaft and drive cog wheels being mounted on a pair of swingable arms whereby the drive cog wheels maintain driving mesh with the ground wheels at all times. The drive mechanism can accommodate ground wheels of different sizes. The drive cog wheels themselves have a bearing formed integrally therewith at one side, and which bearing is journalled in a bearing seat formed in each of the arms. The arms themselves are held in properly spaced relationship so that their bearing seats properly engage and journal the bearings on the drive cog wheels.

    Abstract: An axle driving unit includes an axle, a hydraulic pump, a hydraulic motor having a motor shaft on which an output gear is provided to be drivingly connected to said axle, a center section having a pump mounting surface and a motor mounting surface onto which the hydraulic pump and the hydraulic motor are mounted respectively so as to be fluidly connected with each other through the center section, a housing constituted by a first housing part and a second housing part joined to each other at a joint surface, a projection integrally formed on the center section so as to be fitted to the housing, thereby fixing a position of the center section relative to the housing, and a fastener fastening the center section to the first housing part. The pump mounting surface and said motor mounting surface may be disposed perpendicular to each other. Said pump mounting surface and said motor mounting surface are disposed perpendicular to each other. The projection may be extended in parallel to the pump mounting surface and perpendicular to the motor mounting surface.

    Abstract: An axle driving apparatus for a vehicle includes an axle, a vertical pump shaft, a hydraulic pump having a movable swash plate, a pair of trunnion shafts provided coaxially at respective opposite sides of the movable swash plate, a hydraulic motor having a motor shaft drivingly connected to the axle, and a housing containing the hydraulic pump, the hydraulic motor, and the axle. The housing includes a first housing member and a second housing member separably jointed along a vertical plane perpendicular to a rotary axis of the axle. A rotary axis of the hydraulic pump is substantially parallel to the vertical plane. The hydraulic pump is entirely disposed in the first housing member. A rotary axis of the trunnion shafts is substantially perpendicular to the vertical plane. One of the trunnion shafts is rotatably supported by the first housing member and the other of the trunnion shafts is rotatably supported by the second housing member, whereby the movable swash plate is slantingly rotatably supported in the housing.
