Abstract: A spraying machine includes a machine body, a support frame, and a spraying portion. The support frame includes a horizontal frame having a length along a left-right direction, and a pair of vertical frames and each having a length along an up-down direction, and protruding downward from both ends of the horizontal frame. The spraying portion is supported by the support frame, and sprays a spraying material. The support frame is supported by the machine body to be rotatable around a rotation axis passing through a fulcrum portion provided on the horizontal frame and extending along a front-back direction, while maintaining a relative positional relationship between the pair of vertical frames and the horizontal frame.

Abstract: Outer rear end surfaces of a pair of front frames are connected to corresponding inner front end surfaces of a pair of main frames with spacers being interposed therebetween. Accordingly, a width between the front frames is independent of a width between the main frames, so that maximum steerable angles of front wheels can be increased as much as possible without increasing a mounting pitch of the front wheels. The front frames can be arranged such that at least upper regions of the rear end surfaces thereof are located forward of the mount flange, and the engine unit and the flywheel unit are supported by the vehicle frames such that at least lower portions thereof overlap the vehicle frames in a side view, and the mount flange overlap the upper regions of the rear end surfaces of the front frames in a front view.

Abstract: An outer surface of a rear end of each of a pair of front frames is connected to an inner surface of a front end of the corresponding one of a pair of main frames with a spacer being interposed therebetween. Accordingly, a spacing width between the pair of front frames can be defined freely and independently of a spacing width of the pair of main frames, so that maximum steerable angles of front wheels can be increased as much as possible without increasing a mounting pitch of the pair of front wheels. Preferably, the pair of front frames are arranged such that at least upper regions in rear end surfaces thereof are located forward of the mount flange, and the engine unit and the flywheel unit are supported by the vehicle frames such that at least lower portions thereof are overlapped with the vehicle frames in a side view and the mount flange is overlapped with the upper regions in the rear end surfaces of the front frames in a front view.

Abstract: A mower tractor (1) comprises: a mid-mount mower (5) under a middle bottom portion thereof between front wheels (2;2) and rear wheels (3;3); a body frame (8); a transmission casing (24) having an input shaft (58) disposed laterally eccentrically in the body frame (8); an engine (23) having an output shaft (55); a propeller shaft (14) and universal joints (27) interposed between the output shaft (55) of the engine (23) and the input shaft (58) of the transmission casing (24); and a device (60) for restricting height of the mower (5) disposed between the propeller shaft and the body frame.

Abstract: A tractor comprising a vehicle frame, an engine including a flywheel, a first vibration isolator through which the engine is supported by the vehicle frame, and a transmission including an input shaft and a housing, wherein the input shaft is disposed at an upper portion of the housing and lower than a rotary axis of the flywheel. A pair of first and second universal joints are interposed between the flywheel and the input shaft. The first universal joint being nearer to the flywheel than the second universal joint. A second vibration is isolator interposed at least either between the flywheel and the first universal joint or between the input shaft and second universal joint.
