<p><P>PROBLEM TO BE SOLVED: To provide a machinery for plant husbandry to perform the main speed-change operation and a working part speed-change operation with separate speed-change levers and enabling easy main speed-change operation and working part speed-change operation. <P>SOLUTION: The machinery 1 for plant husbandry is provided with a traveling part 4, a working part 5, an engine 2 for driving the traveling part 4 and the working part 5, a transmission 3 having a traveling gear 3a to transmit the power of the engine 2 to the traveling part 4 and a working part gear 3b to transmit the power to the working part 5, a main speed-change lever 10 to change the speed of the traveling gear 3a, and a tilling speed-change lever 20 to change the speed of the working gear 3b. The machinery 1 is further provided with a working mode switching means to shift the tilling speed-change lever 20 to an operation position to break the power transmission to the working part 5 when the main speed-change lever 10 is shifted to an operation position to perform the backward motion of the traveling part 4. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
