<P>PROBLEM TO BE SOLVED: To efficiently drive an engine and an electric motor mounted on a tractor by considering load characteristics of the tractor mounting a working machine. <P>SOLUTION: The tractor connects a transmission case 2 and a generator 3 through a power division mechanism 8 to the output shaft of the engine 1, supplies electric power generated with the generator 3 to a battery 5 and the electric motor 6 through an invertor 4, connects the output shaft of the electric motor 6 to the transmission case 2, and drives a traveling device 7 from the transmission case 2. The tractor can drive the traveling device 7 with driving force of the engine 1 and the electric motor 6 during working and traveling. In addition, the tractor determines a working and traveling time by switching on of a PTO drive switch 9 and switching on of a working machine lowering switch 10 for switching on and off the drive of the mounted working machine. <P>COPYRIGHT: (C)2012,JPO&INPIT |
