[Scope of claims for utility model registration]. 〒τ: A tie bar that connects two to two, a lift arm whose base is pivoted to the upper part of the frame, one end of which is pivoted to the lift arm, and the other end of which is pivoted to the lower part of the frame. A bronch loader comprising a frame stay, the hydraulic cylinder device having its other end pivotally attached to the lower portion of the frame, and a vertical portion having a proximal end fixed to the lower portion of the frame and extending forward therefrom. In this attachment device to a tractor, a shaft is fixed to one of the four sides of the front portion of the vehicle body of the tractor and the rear side of the vertical portion of the frame stay, and the shaft is fixed to the other side. A hook that can be engaged with the front loader is provided, and odd-shaped hooks are fixed to both sides of the vehicle body portion of the tractor near the driver's seat, which is rearward of the vehicle body front portion of the tractor. 2 above
A pin capable of engaging with each of the irregularly shaped hooks is rotatably supported at the lower end of the book fly.
The irregularly shaped hook has an opening with which the pin engages, and a guide groove car that guides the pin to the opening of the irregularly shaped hook when the irregularly shaped hook and pin are engaged by moving the tractor. The front raising pin can take either a locked state or an unlocked state with the odd-shaped hook depending on its angular position, and the tie bar has one end that is connected to the pair of left and right hooks. The tie bar is pivotally connected to the upper end of one of the frames and is rotatable between a first position located above the vehicle body and a second position located off the top of the vehicle body, and the other end of the tie bar is When the tie bar is in the first position, it can be locked to the upper end of the other frame by a locking member, and the two pins. One of the pins is operatively connected to the locking member by the first coupling means so that the pin is in the locked state when the locking member is in the locked state and in the unlocked state when the locking member is in the unlocked state. The other pin is in a locked state when the tie bar is in the first position, and the other pin is in a locked state when the tie bar is in the second position. A mounting device for a tractor of a front loader, characterized in that the device is operatively connected to the one end of the tie bar via a second connecting member so as to be in an unlocked state.
