Claims

[Scope of Claim for Utility Model Registration] 1. The upper parts of the left and right transmission cases 13 that pivotally support the drive wheels 6 are respectively attached to the left and right sides of the transmission case 7 so as to be vertically swingable, and the left and right transmission cases 1
3 are connected by a horizontal connecting arm 15 that is located in the center between these cases and can swing left and right about a fulcrum shaft 18 that is pivotally supported by the frame 1, so that the connecting arm 15 and the frame 1 are connected by A transplanter is provided with a swing adjustment mechanism C for swinging and fixing the connecting arm 15, and a vertical adjustment mechanism D for changing the position of the fulcrum shaft 18 of the connecting arm 15 up and down with respect to the frame 1. , vertical adjustment mechanism D
1. A vertical adjustment device for a drive wheel in a transplanter, characterized in that a swing adjustment mechanism C is interposed between a member constituting the and a connecting arm 15. 2. The vertical adjustment device for a drive wheel in a transplanter as set forth in item 1, wherein the connecting arm 15 and the left and right transmission cases 13 are connected via a telescoping mechanism B.
