According to the present invention, the deflection reversal of a dual-use multi-pear that is towed by being connected to a three-point suspension mechanism of a tractor is automatically and smoothly performed in conjunction with the vertical movement of the three-point suspension mechanism. In this case, the stopper piece rotatably attached to the machine frame is provided to protrude so as to selectively engage and disengage into the engagement recess in the guide elongated hole of the spindle metal fitting, so there is no possibility of failure of the stopper pusher metal fitting. In conjunction with the operation, the set deflection reversal position of the expropriation umbrella can be reliably maintained by the switching operation of the stopper piece, and even when multiple expropriation umbrellas are connected, each expropriation can be The canopy body can be reliably deflected and reversed in the same direction.

In addition, the rear end of the tension cable whose front end was connected to the lower part of the tractor body was removably connected to the front end of the operating fitting, so by separating this tension cable from the operating fitting, the expropriation umbrella The automatic deflection reversal function can be easily and reliably suppressed, and as a result, it can be easily converted into a single-use pear for use, and therefore has the mechanism of an expropriation multiple-series falcon with a simple structure. However, it can also be used as a single use, providing a highly versatile multi-use use.
