させることができる。Furthermore, if it is necessary to raise the work equipment 11 higher due to the upper limit of the work equipment 11 due to over a ridge, etc., disconnect the clutch installed in the power transmission path to the work equipment 11, and then place the work equipment 11 at the right end in the figure. Even if the operating lever 5 is rotated all the way to the left end where it is stopped by the stopper 22, the power to the work implement 11 is cut off, so no abnormal noise will be emitted from the universal joint shaft. , the work implement 11 can be safely raised to the highest position.
操作レバー５を回動して作業機１１を最上昇位置に上昇
させた場合、誤って操作レバー４を下降位置へ回動して
も作業機１１は下降しないので安全である。When the operating lever 5 is rotated to raise the working implement 11 to the highest position, it is safe because the working implement 11 will not be lowered even if the operating lever 4 is accidentally rotated to the lowered position.
さらに、操作レバー５と作業機１１への動力伝達経路に
配設したクラッチとを連動せしめ、操作レバー５を作業

できるのである。This device is constructed as described above, and for example, when performing a turning operation near a headland, the low position operating lever 4 must be rotated to its maximum upward rotation position. This allows the machine to be turned around without any hindrance by raising the work equipment while it is still rotating, and the work after turning can be started quickly. When crossing the
By disengaging the clutch of the PTO shaft and rotating the high-position operating lever 5 to its maximum lifting rotation position, the work equipment can be lifted sufficiently high.
There is no need to pay special attention to the rotation noise of the universal joint shaft,
By fully rotating the operation lever 4 or 5 depending on the case, the working machine can be raised safely.
