ーリング自在に構成している機種では、作業時には対地
作業装置の対地高さを一定に保つ姿勢制御を行う関係か
ら、走行車輪のローリング動作を固定する必要がある。For agricultural vehicles such as riding rice transplanters and agricultural tractors,
As mentioned above, in models where the V-shaped ground work equipment can be raised and lowered and the running wheels can be rolled, the rolling movement of the running wheels is necessary because the posture control is performed to keep the height of the ground work equipment constant during work. needs to be fixed.
従って、作業を開始する際には上昇位置にあった対地
作業装置を下降操作すると共に、走行車輪のローリング
動作の固定操作を行っていた。Therefore, when starting work, the ground work device that was in the raised position is lowered, and the rolling motion of the traveling wheels is fixed.

縦者ｒことって煩わしいものとなっていた。Therefore, for example, in a riding-type rice transplanter, which is an example of an agricultural vehicle, when starting the planting work, in addition to lowering the planting device, which is a ground-based work device, and rolling and fixing the traveling wheels, operations such as setting markers are performed. The pilot had to perform many operations at the same time, making it troublesome for the operator.
ここで本発明の目的は、対地作業装置の下げ作動に連動
して走行車輪のローリング固定操作も同時に行えるよう
な機構を構造簡単に構成することＶこある。It is an object of the present invention to provide a mechanism with a simple structure that can simultaneously perform a rolling fixing operation of the traveling wheels in conjunction with the lowering operation of the ground work device.
本発明の特徴は前記した農作業車Ｖこおいて、リンク機
構の下げ作動に伴い、走行車輪のローリング動作を不能
にするストッパーを前記リンク機構に設けてあることに
あり、その作用及び効果は、次の通りである。A feature of the present invention is that in the above-mentioned agricultural vehicle V, the link mechanism is provided with a stopper that disables the rolling motion of the traveling wheels as the link mechanism is lowered, and its operation and effects are as follows: It is as follows.
前述のような構造とすれば、対地作業装置を下降側に操

従って、従来行っていた走行車輪のローリング動作の固
定操作が不要となる。With the above-described structure, when the ground work device is operated to the lowering side, the link mechanism supporting the ground work device is lowered, and the stopper provided in the link mechanism P is accordingly moved.
The rolling motion of the traveling wheels is fixed by entering the position where the rolling motion of the traveling wheels is disabled.
Therefore, the fixed operation of the rolling motion of the traveling wheels, which was conventionally performed, is no longer necessary.
