<P>PROBLEM TO BE SOLVED: To solve a problem with a conventional agricultural working implement with a ground wheel and a working device attached to a tool bar for transmitting the rotation power from the ground wheel to the drive shaft, wherein the ground wheel cannot be sufficiently lowered in the high ridge work using the ground wheel for low-ridge work so that the ground wheel is floated from the ground surface and the grounding capability is impaired. <P>SOLUTION: A support body 110 for supporting the ground wheel 33 to the tool bar 15 includes: a first support body 111 having a power take-out part 119 for taking out the rotation power from the ground wheel 33 at a prescribed position above the ground wheel 33; and a second support body 112 for displacing and supporting the power take-out part 119 in one vertical direction above or below the tool bar 15 in addition to a pressing mechanism 116 for energizing the ground wheel 33 journaled to the lower end downward to a prescribed lower-limit position from the tool bar 15. The support body also includes an inverting displacement structure 99 which can change the height of the ground wheel 33 by displacing and supporting the power take-out part 119 in the other direction below or above the tool bar 15 by the inverting operation of at least part of the second support body 112. <P>COPYRIGHT: (C)2012,JPO&INPIT |
