Abstract
Front-rotary working machine employs a vertical engine having an output shaft projecting downward, and a transmission case, provided beneath the vertical engine, has a flat underside so as to extend generally parallel to the ground surface to be cultivated. Distance between left and right transporting wheels, connected to a driving shaft at a rear end portion of the transmission case, can be reduced as necessary. With these arrangements, it is possible to reduce the overall width of the front-rotary working machine.
Claims17
A front-rotary working machine for performing work on a ground surface, comprising:
- an engine;
- a transmission case disposed below the engine;
- front and rear driving shafts operatively connected to the engine and projecting from front and rear portions, respectively, of the transmission case;
- transporting wheels disposed rearwardly of the engine and being driven by the rear driving shaft;
- and
- a rotary working unit having an axis of rotation disposed forward of the engine and being driven by the front driving shaft;
- wherein the transmission case has a generally flat bottom surface disposed above the axis of rotation of the rotary working unit and extending substantially parallel to a ground surface on which the working machine performs work.
A front-rotary working machine comprising:
- a vertical engine having an engine body, and an output shaft projecting downward from the engine body;
- a transmission case disposed below the vertical engine so that the transmission case has a larger dimension in a front-and-rear direction of the working machine than in a widthwise direction of the working machine, the transmission case having a plurality of intermediate shafts extending horizontally in the widthwise direction of the working machine and being arranged in succession along the front-and-rear direction of the working machine;
- a drive shaft projecting laterally from opposite sides of a rear end portion of the transmission case;
- left and right transporting wheels respectively connected to opposite end portions of the drive shaft;
- and
- a rotary working unit disposed in front of the transmission case.
