PROBLEM TO BE SOLVED: To provide a riding type rice transplanter equipped with balance weights to prevent the elevation on the front side of a travel machine frame, which improves the lateral balance of the machine frame on ordinary operations and also uses a bumper as a balance weight-supporting member to reduce the cost.SOLUTION: The riding type rice transplanter equipped with balance weights 13 to prevent the elevation on the front side of the travel machine frame 2 is characterized by dividing a bumper 12 disposed along the front end portion of the machine frame into a left bumper 12L and a right bumper 12R on the flat view, disposing the balance weights 13L, 13R in the outer end portions of the left bumper 12L and the right bumper 12R, respectively, and arranging the left bumper 12L and the right bumper 12R in a state that the left bumper 12L and the right bumper 12R can forward be rotated on the lateral center of the front end portion of the machine frame as a fulcrum, and moving the left and right balance weights 13L, 13R from the lateral angled portions of the front end portion of the machine frame in the forward direction of the machine frame in response to the rotation.COPYRIGHT: (C)2011,JPO&INPIT【課題】走行機体の前上がりを抑制するバランスウェイトを備えた乗用型田植機において、通常時における機体の左右バランスを改善すると共に、バンパをバランスウェイト支持部材に兼用してコストを削減する。【解決手段】走行機体2の前上がりを抑制するバランスウェイト13を備えた乗用型田植機において、平面視で機体前端部に沿って設けられるバンパ12を左右に分割すると共に、左側バンパ12L及び右側バンパ12Rの外端部にそれぞれバランスウェイト13L、13Rを設け、さらに、左側バンパ12L及び右側バンパ12Rを、機体前端部の左右中央部を支点として前方へ回動可能に構成し、この回動に応じて、左右のバランスウェイト13L、13Rを機体前端部の左右角部から機体前方へ移動させる。【選択図】図2
